    Abstract: A swing mechanism for a construction machine is provided with a center frame 3 having a pinion insertion hole 3c, an inner race having an internal gear and mounted on a side of an undercarriage, an outer race 1b rotatably arranged surrounding the inner race and provided with the center frame secured thereon by bolts 8a, a pinion maintained in meshing engagement with the internal gear of the inner race, and a pinion drive device. A pin fit-in hole 3d arranged in the center frame 3 such that a knock pin 6 fixed on the outer race 1b is fitted in the pin fit-in hole to position the center frame 3. To arrange the pin fit-in hole 3d in the center frame 3, a pin fit-in hole portion 20 through which the pin fit-in hole 3d is formed is locally arranged such that the pin fit-in hole portion 20 extends toward the pinion insertion hole 3c to have a center of the pin fit-in hole 3d located on a center connection line S. This construction allows to perform smooth assembly of the pinion drive device while enabling to optimally arrange the knock pin for positioning the center frame.

    Abstract: Apparatus for reducing backlash in a gear wheel that includes at least two interacting gear rims that rotate in relation to one another. An adjusting mechanism is located between the gear rims for adjusting the relative angle of rotation of the gear rims about a common axis of rotation. Each adjusting mechanism includes an hydraulic cylinder connected to a pressure medium source and which is arranged to act between the two gear rims in such a manner that a force arises that tends to displace one gear rim in relation to the other about the axis of rotation. Each of the hydraulic cylinders extends at an angle to a disk plane and is supported on a part-spherical foot portion in a bowl-shaped seat in one gear rim and a corresponding part-spherical head portion in a bowl-shaped seat in the other gear rim.

    Abstract: A gearing radius of a worm wheel is set corresponding to a neighborhood region of a steering neutral position, in such a way as to be relatively large. Thus, backlash is made to be relatively small. This prevents noises from being produced when an automobile travels straight on a bad road. Conversely, the backlash is set corresponding to most of regions of steering angles, which are within the remaining region thereof, in such a manner as to be relatively large. Thus, increase in resistance torque is suppressed. This is realized by a simple configuration in which a bias portion is provided in a part of the profile of teeth. In a case where power is transmitted from an electric motor by a worm shaft and a worm wheel during a steering operation, noises are hard to be produced even when the automobile travels on a bad road.

    Abstract: A mechanism for de-lashing a gear assembly includes a first gear rotatable about a first axis and a first center rotatably fixed to the first axis and a first conical teeth portion. The gear assembly includes a second gear rotatable about a second axis and a second center rotatably fixed to said second axis and a second conical teeth portion configured to meshingly engage first conical teeth portion when the first and second gears are aligned substantially coplanarly. A biasing means operably biases the second conical teeth portion of the second gear against the first conical teeth portion of the first gear to reduce any lash therebetween. The biasing means is configured to bias the second gear in an axial direction while maintaining a fixed center distance between the first and second axes. The first gear is rotatably fixed about the fixed first axis such that the first gear is prevented from translation along the fixed first axis.

    Abstract: A worm 1 is composed of an annular tooth body 11 having a tooth 10 on the outer surface thereof, a core body 12 inserted inside the annular tooth body 11; and an elastic coupler 13, which can be transformed in the radial direction, for coupling the core body 12 with the annular tooth body 11. The worm 1 is engaged with the worm wheel with the elastic coupler 13 being transformed in the radial direction in such a manner that a negative amount of backlash is generated at the engagement portion. This can be also employed for the worm wheel. With a reduction gear combination having this structure, the backlash amount at the engagement portion can be adjusted to a proper amount without selecting elements such as the worm and the worm wheel to be assembled.

    Abstract: A gear drive, including a first shaft, a first gear wheel on the first shaft, a second shaft a certain distance away from the first shaft, and a second gear on the second shaft. The second gear wheel engaged with the first gear wheel by way of helical gearing. A third gear wheel is mounted on the second shaft a certain axial distance away from the second gear wheel to compensate for backlash. The third gear wheel also engages with the first gear wheel by way of helical gearing and being axially shiftable with respect to the second gear wheel. An expansion element is arranged so as to change a distance between the second gear wheel and the third gear wheel as a function of temperature. The expansion element has a thermal expansion selected so that, when the expansion element undergoes thermal expansion, the expansion element shifts the third gear wheel in an axial direction along the second shaft and thus, due to a helical gearing effect, compensates for play caused by a thermally induced change in the distance between the first shaft and the second shaft.
