Gear Housing
The gear housing is a mechanical housing that surrounds the mechanical components of a gear box. It provides mechanical support for the moving components, a mechanical protection from the outside world for those internal components, and a fluid-tight container to hold the lubricant that bathes those components. Types of housings A split housing is like a walnut shell, the housing is divided in two parts, and lower part that tie down the Gear Box to the structure, support all the components during the assembly stage and hold the lubrication oil; and the upper part that complete the enclosure and provide mechanical integrity to the Housing. The upper and lower parts of the housing have a mating surface that seals perfectly the housing to avoid oil leaks and fatigue of the housing. A bathtub housing is made on a single piece and have a top opening for servicing the gear box and side opening to accommodate the bearing housing associated to the gear shafts. Have in general a better le ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mechanical Housing
In engineering, a housing or enclosure is a container, a protective exterior (e.g. shell) or an enclosing structural element (e.g. chassis or exoskeleton) designed to enable easier handling, provide attachment points for internal mechanisms (e.g. mounting brackets for electrical components, cables and pipings), maintain cleanliness of the contents by shielding dirt/dust, fouling and other contaminations, or protect interior mechanisms (e.g. delicate integrated electrical fittings) from structural stress and/or potential physical, thermal, chemical, biological or radiational damages from the surrounding environment. Housing may also be the body of a device, vital to its function. Description Housing is an exterior case or enclosure used to protect an interior mechanism. The housing prevents the interior mechanism from being fouled by outside debris. It may also have integrated fittings or brackets to keep internal components in place; sometimes a housing is the body of the devic ...

Transmission (mechanics)
Propulsion transmission is the mode of transmitting and controlling propulsion power of a machine. The term ''transmission'' properly refers to the whole drivetrain, including clutch, gearbox, prop shaft (for rear-wheel drive vehicles), differential, and final drive shafts. In the United States the term is sometimes used in casual speech to refer more specifically to the gearbox alone, and detailed usage differs. The transmission reduces the higher engine speed to the slower wheel speed, increasing torque in the process. Transmissions are also used on pedal bicycles, fixed machines, and where different rotational speeds and torques are adapted. Often, a transmission has multiple gear ratios (or simply "gears") with the ability to switch between them as the speed varies. This switching may be done manually (by the operator) or automatically (by a control unit). Directional (forward and reverse) control may also be provided. Single-ratio transmissions also exist, which simply ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Triumph Gearbox With Overdrive
The Roman triumph (Latin triumphus) was a celebration for a victorious military commander in ancient Rome. For later imitations, in life or in art, see Trionfo. Numerous later uses of the term, up to the present, are derived directly or indirectly from the Roman one. Triumph may refer to: Geography * Triumph, Idaho * Triumph, Illinois * Triumph, Louisiana * Triumph Township, Custer County, Nebraska * Triumph Township, Warren County, Pennsylvania * Triumph, Guyana Business * Triumph (TWN), a defunct German motorcycle manufacturer * Triumph Cycle Co.

Permanent Mold Casting
Permanent mold casting is a metal casting process that employs reusable molds ("permanent molds"), usually made from metal. The most common process uses gravity to fill the mold, however gas pressure or a vacuum are also used. A variation on the typical gravity casting process, called slush casting, produces hollow castings. Common casting metals are aluminium, magnesium, and copper alloys. Other materials include tin, zinc, and lead alloys and iron and steel are also cast in graphite molds.. Typical products are components such as gears, splines, wheels, gear housings, pipe fittings, fuel injection housings, and automotive engine pistons. Process There are four main types of permanent mold casting: gravity, slush, low-pressure, and vacuum. Gravity process The gravity process begins by preheating the mold to 150–200 °C (300–400 °F). to ease the flow and reduce thermal damage to the casting. The mold cavity is then coated with a refractory material or a mold ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shell Molding
Shell molding, also known as shell-mold casting, is an expendable mold casting process that uses resin covered sand to form the mold (manufacturing), mold. As compared to sand casting, this process has better dimensional accuracy, a higher productivity rate, and lower labour requirements. It is used for small to medium parts that require high precision.. Shell molding was developed as a manufacturing process during the mid-20th century in Germany. It was invented by German engineer Johannes Croning. Shell mold casting is a metal casting process similar to sand casting, in that molten metal is poured into an expendable mold. However, in shell mold casting, the mold is a thin-walled shell created from applying a sand-resin mixture around a pattern. The pattern, a metal piece in the shape of the desired part, is reused to form multiple shell molds. A reusable pattern allows for higher production rates, while the disposable molds enable complex geometries to be cast. Shell mold casting r ...

Composite Gear Housing
Composite gear housing refers to the use of composite materials to enclose the components of motor transmissions. Fiber reinforced composite materials are used primarily for weight reduction. Carbon fiber reinforced plastic material is commonly used in the aerospace and automotive industries. Design The main problems of using Fiber reinforced plastic for gear housings are low thermal conductivity and low hardness of the composite material. Because of the low hardness, the composite gear housing requires numerous metal inserts laminated into the composite exterior or installed with adhesive in the prefabricated composite housing. High strength epoxy adhesives are used in fabrication of carbon fiber composite drive shafts for cars. The metal inserts provide support for bearings, shafts, gears and other metal components of the gearbox. The composite gear housing does not remove heat as efficiently as an aluminum or magnesium housing. Composite gear housings require more expe ...

Overdrive (mechanics)
Overdrive is the operation of an automobile cruising at sustained speed with reduced engine revolutions per minute (RPM), leading to better fuel consumption, lower noise, and lower wear. The term is ambiguous. The most fundamental meaning is that of an overall gear ratio between engine and wheels, such that the car is ''over-geared'', and cannot reach its potential top speed, i.e. the car could travel faster if it were in a lower gear, with the engine turning at higher RPM. The power produced by an engine increases with the engine's RPM to a maximum, then falls away. The point of maximum power is somewhat lower than the absolute maximum RPM to which the engine is limited, the "redline" RPM. A car's speed is limited by the power required to drive it against air resistance, which increases with speed. At the maximum possible speed, the engine is running at its point of maximum power, or ''power peak'', and the car is traveling at the speed where air resistance equals that m ...

Spiral Bevel Gear
A spiral bevel gear is a bevel gear with helical teeth. The main application of this is in a vehicle differential, where the direction of drive from the drive shaft must be turned 90 degrees to drive the wheels. The helical design produces less vibration and noise than conventional straight-cut or spur-cut gear with straight teeth. A spiral bevel gear set should always be replaced in pairs i.e. both the left hand and right hand gears should be replaced together since the gears are manufactured and lapped in pairs. Handedness A right hand spiral bevel gear is one in which the outer half of a tooth is inclined in the clockwise direction from the axial plane through the midpoint of the tooth as viewed by an observer looking at the face of the gear. A left hand spiral bevel gear is one in which the outer half of a tooth is inclined in the counterclockwise direction from the axial plane through the midpoint of the tooth as viewed by an observer looking at the face of the gear. No ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ford Type 9 Transmission
Type 9 (also, Type N, T9, or T-9) is a gearbox from Ford that was used in Ford Capri 1.6, 2.0 1984 onwards, Capri 2.8 1983 onwards, Ford Sierra 1.6, 1.8, 2.0, Sierra XR4i, Sierra XR4x4 2.8 and the Scorpio 4x4 as well as the US market Merkur XR4Ti and Merkur Scorpio. The Type 9 was Ford's first five-speed, rear-wheel-drive gearbox, and it is based on the four-speed Type E gearbox. The fifth, or overdrive gear, was added to the four-speed gearbox by placing it in the extension housing or tailshaft housing. This made production easier and cheaper but effectively limited torque capacity to 200 lb. ft. or so. The Type 9 is a popular choice for five-speed conversions of older Ford cars such as the Cortina and rear wheel drive Escorts, and also for kit car builders, since it comes with a separate bell housing so it can be easily swapped around. Engines that were originally in FWD layouts are fitted to these transmissions so that they can go into a RWD layout, as in a hot rod engine swap ...
