Abstract
The utility model relates to a hub speed reduction axle gear ring. The gear ring comprises a gear ring body, a gear-shaped portion and a gear ring bottom. The gear-shaped portion extends to the gear ring bottom, and the gear-shaped portion and the gear ring bottom form a whole. Due to the fact that the gear-shaped portion extends to the gear ring bottom, and the gear-shaped portion and the gear ring bottom form the whole, when the gear shape bears circumferential pressure, the side, close to the bottom, in the direction of the gear length is supported by the gear ring bottom, and the deformation of the gear shape is reduced. Meanwhile, due to the fact that the bottom is additionally arranged on the gear ring, the rigidity of the gear ring is improved greatly, deformation of the whole gear ring and the gear shape is effectively lowered in the work process, the correct meshing position of the gear shape is guaranteed, and the cracking probability of the gear ring body is lowered.
Description
Technical field
The utility model belongs to gear ring processing technique field, particularly a kind of wheel-hub reduction axle gear ring.
Background technique
At present; wheel-hub reduction axle gear ring is a kind of gear ring of communicating structure; the advantage of this gear ring is that profile of tooth can adopt gear shaping or draw tooth processes; shortcoming is that Rigidity and strength is on the low side; cause the gear ring of thinner thickness to produce in the course of the work gross distortion; on the larger dumping car of carrying capacity, problem is more outstanding, often there will be and plays tooth and gear ring fracture.Because cog machining generally adopts gear shaping or draws tooth technique, take gear shaping technique as main, and gear shaping process is by calibration shaping, and therefore wheel-hub reduction axle gear ring profile accuracy mainly depends on slotting machine, and precision can be too not high.No matter gear shaping still draws tooth, all steel fiber originally continuous in gear ring can be cut off, so the profile of tooth intensity of these two kinds of processes is lower, under large torque conditions, there is beating tooth.Because the Blade edge radius of gear shaper cutter and broaching tool can not be excessive, the tooth root place fillet radius therefore processing is less, and stress is concentrated serious, causes gear ring body easily to occur breakage problem at tooth root place.
Summary of the invention
The technical problems to be solved in the utility model is to provide the wheel-hub reduction axle gear ring that a kind of Rigidity and strength obtains improving by a relatively large margin.
In order to solve the problems of the technologies described above, wheel-hub reduction axle gear ring of the present utility model comprises gear ring body, parts of tooth and gear ring bottom; Described parts of tooth extends to gear ring bottom and forms one with gear ring bottom.
The utility model is because parts of tooth extends to gear ring bottom and forms one with gear ring bottom, and in the time that profile of tooth is subject to circumferential pressure, tooth length direction obtains the support of gear ring bottom near a side of bottom, the amount of deformation of profile of tooth is reduced.Meanwhile, because gear ring has added bottom, the rigidity of gear ring obtains raising by a relatively large margin, has effectively reduced the distortion of gear ring entirety and profile of tooth in working procedure, has guaranteed the correct engagement position of profile of tooth, has reduced the probability of gear ring body cracking.
Round-corner transition is passed through in described parts of tooth bottom and gear ring bottom along its length.
The utility model can adopt cold hobbing or warm extrusion technology single forming, the follow-up cutting of no longer carrying out of profile of tooth, owing to there is no clearance groov between profile of tooth and gear ring bottom, between parts of tooth, gear ring bottom and gear ring body, steel fiber is continuous, has further improved gear ring rigidity, intensity and working life.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is wheel-hub reduction axle gear ring plan view of the present utility model.
Fig. 2 is wheel-hub reduction axle gear ring parts of tooth of the present utility model and joint, gear ring bottom partial enlarged drawing.
Embodiment
As shown in Figure 1, 2, wheel-hub reduction axle gear ring of the present utility model comprises gear ring body 1, parts of tooth 2 and gear ring bottom 3; Described parts of tooth 2 extends to gear ring bottom 3 and forms one with gear ring bottom 3; The round-corner transition that bottom along its length of parts of tooth and gear ring bottom are R by radius.
Claims (2)
1. a wheel-hub reduction axle gear ring, comprises gear ring body (1), parts of tooth (2), characterized by further comprising gear ring bottom (3); Described parts of tooth (2) extends to gear ring bottom (3) and forms one with gear ring bottom (3).
2. wheel-hub reduction axle gear ring according to claim 1, is characterized in that bottom along its length of described parts of tooth (2) and gear ring bottom (3) pass through round-corner transition.
