Automobile gearbox housing belongs to a kind of typical box and shell parts. The main shape and inner cavity shape are finished by casting. The main machined mounting surface and multiple mounting holes on the same or different surfaces (hole types include through holes, blind Holes, screw holes, step holes, etc.), process requirements: the blanks are generally cast iron or cast aluminum. The main processes include: casting-aging treatment-milling-drilling and tapping processes; the main processing equipment has a machining center (three Axis, four axis, five axis, etc.). Key inspection items: surface roughness, flatness, hole position, hole cylindricity, etc. Key inspection equipment: large and medium-sized precision three-coordinate measuring machine automobile gearbox housing.
The automobile gearbox housing prevents lubricating oil from flowing out of the rear end of the second shaft. An oil seal assembly is installed in the rear bearing cap of the transmission. Install sealing gaskets on the joint surfaces of each bearing cover, rear cover, upper cover, front and rear housings, etc., and apply sealant to prevent oil leakage. In order to prevent lubricating oil from leaking due to the increase of oil temperature and pressure when the transmission is working, a vent plug is installed on the transmission mechanism seat and the rear bearing cover of the transmission.
Automobile gearbox housings are used in automobile gearboxes. They are typical box and shell parts, similar to most box shell parts; in order to reduce part wear and power loss caused by internal friction, lubrication must be injected into the shell Oil, using splash lubrication to lubricate the working surfaces of various gear pairs, shafts and bearings. Therefore, there is an oil filling port on one side of the casing and an oil drain plug at the bottom, and the oil level is controlled by the position of the oil filling port. Radial oil holes are drilled on the first shaft constant meshing gear and the third gear on the second shaft. The reverse intermediate gear and the intermediate shaft constant meshing transmission gear have radial oil grooves on the hub end faces.
