Embodiment
Below embodiment of the present utility model is elaborated; the present embodiment is implemented under premised on technical solutions of the utility model; give detailed mode of execution and concrete operating process, but protection domain of the present utility model is not limited to following embodiment.
Embodiment 1
As shown in Figure 1, the present embodiment comprises: the tooth hub 1 that reverses gear, driven tooth of reversing gear 2, the tooth that reverses gear cover 3, the conical ring 4 that reverses gear, reverse gear in conjunction with tooth 5 and jack shaft 6, wherein: jack shaft 6 is connected with the tooth hub 1 that reverses gear, driven tooth of reversing gear 2, reversing gear 3 to be connected with the tooth hub 1 that reverses gear with the conical ring 4 that reverses gear respectively in conjunction with tooth 5, the tooth that reverses gear cover, driven tooth of reversing gear 2 is overlapped 3 with the tooth that reverses gear and is contacted, and the conical ring 4 that reverses gear overlaps 3 and reverse gear and to contact in conjunction with tooth 5 respectively with the tooth that reverses gear.
Described driven tooth 2 and of reversing gear is kept off driven tooth 7 and is connected.
As shown in Fig. 2 (a), described reverse gear driven tooth 2 and tooth hub 1 laser bonding of reversing gear.
As shown in Fig. 2 (b), described driven tooth 2 and the wedge shape weld penetration reversed gear between tooth hub 1 of reversing gear is more than or equal to 7mm, avoids the cracking risk of weld seam in heavy load situation.
Described wedge shape distance between the toes of a weld is less than or equal to 2.5mm, and driven tooth 2 face deformation of avoiding causing when distance between the toes of a weld is excessive reversing gear is comparatively large, affect gear tooth put into gear after length of action, easy off-gear.
As shown in Figure 1, during neutral position state, the tooth that reverses gear cover 3 contacts with driven tooth 2 of reversing gear; When extension reverses gear, as shown in Figure 3, back fork drives the tooth cover 3 that reverses gear to conical ring 4 one lateral movement of reversing gear, and the tooth that reverses gear cover 3 is separated with driven tooth 2 of reversing gear; The tooth that reverses gear cover 3 by the conical ring 4 that reverses gear produce synchronous after continue move to reversing gear of contacting with the conical ring 4 that reverses gear in conjunction with tooth 5 direction, the tooth that reverses gear overlaps 3 with reversing gear and to engage in conjunction with tooth 5, completes action of putting into gear.
The size of described wedge shape weld seam does not depart from bearing to make under high pulling torque operating mode to reverse gear driven tooth 2 and the tooth hub 1 that reverses gear.
Described driven tooth 6 and of reversing gear is kept off driven tooth 7 and is connected, and carry out integrated with the tooth hub 1 that reverses gear, significantly simplify design of part, driven tooth of reversing gear 2 and the axial spacing between reversing gear in conjunction with tooth 5 are 51.7mm, and the speed changer overall weight using the present embodiment is 64kg; With existing speed changer overall weight 70kg, corresponding position axial spacing is that 61.8mm compares, and have compressed axial spacing, reduces the total quality of speed changer.
