  • Patent number: 6158302
    Abstract: A torque support, especially for wheel blocks, is arranged between a gear unit housing with a drive shaft and a driven unit housing. The torque support includes a plate-shaped base body which is detachably fastened to the gear unit housing with fastening elements. The plate-shaped base plate has at least two fastening locations comprising through openings for fastening the torque support to the driven unit housing. To keep the shearing forces resulting from the torque support and acting on the gear shaft small while the torsional moment is simultaneously absorbed with low play and in such a way that load peaks are damped, a corresponding plastic ring body is inserted into each through-opening in a positive-locking engagement. A side of the plastic ring body facing the driven unit housing has an edge area which widens radially outward forms an elastic disk element arranged between the driven unit housing and the torque support.

  • Patent number: 6155125
    Abstract: A six speed gear assembly is having a mainshaft, countershaft, mainshaft 1st-6th gears, countershaft 1st-6th gears, and 4th/6th gear shift member. A shifting assembly with a shifter cam having uniformly distributed and uniformly shaped detents that are engaged by the shift cam follower. The six speed gear assembly has modes of operation corresponding to six speeds (1st through 6th) and a neutral position. The sixth speed is an overdrive speed (the output from the transmission turns faster than the input to the transmission), while the first through fifth speeds correspond to conventional gear ratios.The six speed gear assembly and the shifting assembly fit within the transmission case of a Big Twin five speed transmission without the need to modify the transmission case. This allows the conversion of a Big Twin five speed transmission into a six speed transmission without removal or replacement of the transmission case and by replacing a minimal number of components.

  • Patent number: 6076419
    Abstract: A plastic gear is rotatably supported on at least one plastic fixed support stud, which is preferably formed of plastic and molded on a metal support plate. The fixed support stud has three equiangularly spaced lobes extending from its outer surface without any nominal clearance with an inner surface of a hub of a plastic gear defining a bore in the gear hub to receive the fixed support stud. The lobes cause deformation of portions of the gear hub between the adjacent lobes. By increasing the clearance between the outer surface of the fixed support stud and the inner surface of the gear hub, spaces are provided between the adjacent lobes to allow portions of the inner surface of the gear hub to extend thereinto due to the deformation of the plastic. This reduces the vibration or jitter of the plastic gear, which is the output gear of a gear train for driving a photoconductive drum of a laser printer to improve its print quality.

The connection piece is provided with ribs (12) over at least a part of its wall, the height of the ribs (12) being at least equal to one and a half times a thickness of the part of the wall upon which the rib is standing and the thickness of the ribs (12), half-way up the height, being equal to at least half of the thickness of the part of the wall. The ribs (12) form a pattern which divides the wall into adjacent wall segments (13) which have a first characteristic mode for bending that has a resonant frequency which excludes excitation by substantially all excitation frequencies up to and including a highest of the compressor element (1).

  • Patent number: 6068571
    Abstract: An adjustment collar for a positioning a ring gear to a differential case. The ring gear is splined to the differential case so as to allow axial displacement. The adjustment collar is threaded onto the differential case adjacent to the ring gear. The adjustment collar is rotated to axially position the adjustment collar, and consequently the ring gear relative to the differential case and axle assembly. The adjustment collar and ring gear are bolted to one another to prevent relative rotation there between. Because the ring gear is splined to the differential case, relative rotation between the ring gear and differential case, and consequently the adjustment collar and the differential case, is prevented. Because the ring gear and adjustment collar are locked to one another, the two components are thus prevented from both axial and rotational movement.

  • Patent number: 6065369
    Abstract: In an air breather structure in a transmission, a partition wall 2 defining an air breather chamber S extends substantially vertically downward in a curved configuration at a distance from a corner portion 1a of a transmission case to increase volume of the air breather chamber S. An oil entrance 4 is formed in an upper portion of the partition wall 2. An oil exit 5 wider than the oil entrance 4 is formed in a lower end portion of the partition wall 2 for discharging oil which enters the air breather chamber S. The oil exit 5 is formed between a lower end of the partition wall 2 and an oil-returning rib 6 projecting from the transmission case for preventing the oil from flowing upward into the air breather chamber S. With this construction, the air breather structure becomes free from "blow of oil".

  • Patent number: 6058805
    Abstract: An assembly that removes air from the housing of an axle assembly in combination with the axle assembly for use with a vhicle. The assembly is vomprised of a modified differential housing having an air flow channel therein extending from an inner chamber of the housing to a face of the differentiao housing which abuts ayoke of a drive shaft, the channel emptying into an area over which an seal protector is engaged for protecting a seal provided between the yoke and the differential, the seal protector having an edge port in a circumferential edge thereof which aligns with a cooperating cored hole in a corresponding circumferential area of the housing intermittently, the seal protector being engaged to the drive shaft yode and rotating therewith. The intermittent alignment of the edge port and the cored hole allows venting of the inner chamber of the differential housing to the outside atmosphere.

  • Patent number: 6058793
    Abstract: A speed reducer for a mixing apparatus having a gear train mounted within a housing such that the output shaft is supported by upper and lower bearings mounted within the upper portion and base of the housing, respectively. The lower output shaft bearing preferably is mounted within a recess in the underside of the housing base below a dry well containing the output shaft. The dry well forms a lubricant sump within the housing and preferably is unitary with the housing base. By placing the output shaft bearing below the dry well in the base of the housing, the diameter of the bearing can be increased to bear larger loads without being restricted by the dry well and is better able to transmit bending and radial loads to a relatively massive portion of the housing, and is placed closer to the load, thereby minimizing the amount of unsupported output shaft projecting from the reducer.

  • Patent number: 6035956
    Abstract: An offset axle (1) for low-platform town buses. It solves the problem of making it possible to integrate disc brakes in the offset axle system without reducing the aisle width of the platform in the vehicle in the area of the axle and obtaining a sufficiently low platform level in spite of the gantry being significantly lowered owing to design requirements. Disposed eccentrically in the offset axle (1) is a differential (2) the axle shafts of which are each inserted into a drive pinion (5) of a gantry drive (3) with demultiplication effect, the drive being freely mounted in a self-centering manner between two intermediate pinions (6) each of which transmits half the drive power to a spur wheel (7) in order to drive the wheels. Owing to the two gantry drives (3), the axle shafts (4) are lower than the wheel axles by the depth of the gantry. The axle shafts (4) are mounted eccentrically on the upper edge of the interior of the axle bridge housing (8).
