Abstract
A transmission device includes a gear case, a first gear, a second gear and a backlash adjusting mechanism. The first gear, the second gear and a backlash adjusting mechanism are received in the gear case. The first gear includes a shaft. The second gear is meshed with the first gear. Both of the first gear and the second gear are bevel gears. The backlash adjusting mechanism includes a resilient member and fastening member. The fastening member passes through the gear case. The resilient member resists the fastening member and an end of the shaft of the first gear, respectively. An elastic variation of the resilient member is changed or adjusted by the fastening member, such that a backlash between the first gear and the second gear is adjusted via the resilient member.
Claims20
A transmission device comprising:
- a gear case defining a threaded hole;
- a first gear comprising a shaft and received in the gear case, the shaft defining a receiving hole in an end surface thereof;
- a second gear received in the gear case and meshed with the first gear;
- and
- a backlash adjusting mechanism comprising a resilient member and a fastening member, wherein both of the first gear and the second gear are a plurality of bevel gears, the fastening member is adjustably engaged in the threaded hole of the gear case, opposite ends of the resilient member are respectively received in the threaded hole and the receiving hole, and resist the fastening member and an end of the shaft of the first gear, respectively, an elastic variation of the resilient member is adjusted by the fastening member, such that a backlash between the first gear and the second gear is adjusted via the resilient member.
A transmission device, comprising:
- a gear case defining a threaded hole
- a first gear comprising a shaft and received in the gear case, the shaft defining a receiving hole in an end surface thereof;
- a second gear meshed with the first gear;
- a fastening member adjustably engaged in the threading hole of the gear case;
- and
- a resilient member resisting the fastening member and an end of the shaft of the first gear, respectively, the resilient member partly received in the threaded hole, and partly received in the receiving hole, wherein both of the first gear and the second gear are a plurality of bevel gears, an elastic variation of the resilient member is changed by the fastening member, such that a backlash between the first gear and the second gear is adjusted via the resilient member.
