A geared motor, e.g., a gear unit or a bevel gear unit, which is able to be driven by an electric motor, includes a housing part, which is produced by a die casting method, during or after which sliders are moved, in particular pulled out, in respective drawing directions for the demolding, and an input shaft. The housing part includes a channel, demolded in a first drawing direction, in particular, using a first slider, the channel being adapted to extend through the wall of the housing and ending in the interior space region of the gear unit. The drawing direction has a non-vanishing angle in relation to the axis of rotation of the input shaft, its angle in particular amounting to between 5° and 45°, e.g., between 5° and 20°.

A speed reducer casing of the present invention has inner teeth on an inner periphery thereof. The speed reducer casing includes an inner tooth portion and a casing body portion, the inner tooth portion including the inner teeth, the casing body portion supporting the inner tooth portion. The inner tooth portion is formed of a material having a higher slidability than the casing body portion. The casing body portion is formed of a material having a higher hardness than the inner tooth portion.

A system and method to add an additional drive axle to a vehicle may include an auxiliary shaft aperture bored through the differential housing and an auxiliary shaft sleeve mounted over the aperture. An auxiliary shaft has a splined end interconnected to a modified pinion and a short transfer drive shaft interconnect disposed on an opposite end thereof, the short transfer drive shaft interconnect extending out from the modified differential housing through the auxiliary shaft sleeve. A short transfer drive shaft is operatively interconnected to the auxiliary shaft and rotational therewith. Further, an additional drive axle assembly is mounted to the vehicle rearward of the original drive axle, and the modified differential is operatively interconnected to an additional drive axle via the short transfer drive shaft, such that when the short transfer drive shaft rotates with the auxiliary shaft, the additional drive axle rotates with the original drive axle.

A pump assembly comprising at least one housing and two gear wheels. The housing comprises at least one base plate and a cover element, which are interconnectable to form a pressure chamber. An outer circumferential surface of each of the two gear wheels has a toothing, and the gear wheels intermesh via the toothings to convey a fluid. The gear wheels are arranged along an axial direction in the pressure chamber between the base plate and the cover element. The pressure chamber is formed in the housing at least by two bores. The first gear wheel is arranged in a first bore and the second gear wheel is arranged in a second bore. Centering pins are provided for aligning the bores and the gear wheels with respect to one another, wherein all centering pins are arranged exclusively in the cover element or exclusively in the base plate.

A transmission includes a transmission main housing, an intermediate plate secured to the transmission main housing; and a rear housing attached to the intermediate plate. An input shaft is connected to an extension shaft including a plurality of splitter gears selectively couple-able to the extension shaft. A main shaft is rotatably supported on the extension shaft and includes a plurality of main box gears selectively couple-able to the main shaft. A range shaft is drivingly connected to the main shaft and provides input to a planetary gear assembly, the range shaft being supported by a first bearing disposed within the intermediate plate and further including a bore disposed within a forward end. The extension shaft is supported at a first end by a bearing assembly within a partition wall and a second end is supported by a bearing assembly disposed within the bore in the range shaft.

A method for attaching a plastic barrel configured to guide an output shaft of a mechanical device to a housing for the mechanical device is disclosed. The housing includes a chimney delimited by an upper edge and a base, the chimney being arranged to partially surround the output shaft, the plastic barrel having a lateral protuberance. The method involves at least the following steps: inserting a first end of the plastic barrel into the chimney of the housing until the lateral protuberance axially abuts against the upper edge of the chimney, and at least partially deforming the first end of the plastic barrel in order to form an axial counter-abutment.

A transmission gear box is provided, which comprises a box body (10), at least one end cover (20, 20′) and a fitting structure. A cavity suitable for arranging gears is defined in the box body (10). The at least one end cover (20, 20′) is fixed on at least one opening end, which is axially opened, of the cavity of the box body (10). The fitting structure comprises an inner fitting surface (11) provided on the surface of the cavity of one of the box body (10) and the end cover (20, 20′), and an outer fitting surface (21) provided on the peripheral surface of the other one of the box body and the end cover, and the inner fitting surface (11) and the outer fitting surface (21) are fixed to each other by means of welding. At least one clearance fit area (30) and interference fit areas (40) located on both sides of the clearance fit area (30) are configured between the inner fitting surface (11) and the outer fitting surface (21). The provided transmission gear box can effectively avoid product deformation caused due to the fact that a molten body presses the box body (10) and the end cover (20, 20′) during welding.

A differential carrier case with an inserted pipe for high pressure casting may include a mold core into which a first end of a pipe is inserted, a mold core pin fixed to the mold core to fix the mold core and the first end of the pipe, a drive core pin inserted into a second end of the pipe, and a thick portion surrounding an outer portion of the pipe.

A steering gear housing and method of manufacturing same are provided. The steering gear housing is comprised of aluminum alloy and is at least partially anodized. The steering gear housing defines a plurality of mounting apertures. A plurality of nuts is fit into a respective one of the mounting apertures for use in mounting to a vehicle. Each of the nuts defines a plurality of splines for establishing a press-fit relationship between the mounting apertures and the nuts. The method involves casting a steering gear housing defining a plurality of mounting apertures out of aluminum alloy. Next, the casted steering gear housing is at least partially anodized. After anodization, a plurality of nuts is fit into respective ones of the mounting apertures. The nuts define splines for allowing a press-fit relationship to be established between the mounting apertures and the nuts.
