Abstract
The invention discloses a cylindrical gear having a vibration reducing structure. The cylindrical gear comprises an inner ring body and an outer ring body, wherein wheel teeth are arranged on an outer cylindrical surface of the outer ring body; grooves are uniformly formed in an inner cylindrical surface of the outer ring body; convex teeth are arranged on an outer cylindrical surface of the inner ring body; the convex teeth are positioned in the grooves; and vibration reducing blocks are arranged in peripheral gaps of the convex teeth and the grooves. The cylindrical gear having the vibration reducing structure is provided with the vibration reducing blocks between the inner ring body and the outer ring body; the gear is suffered from the impact load in engagement, and the outer ring body can apply the pressure in the peripheral direction to the vibration reducing blocks; and the vibration reducing blocks are elastically deformed to absorb the impact energy, so that the vibration reduction of the gear is realized, the gear engagement noise can be lowered, the harm of the impact to the wheel teeth can be prevented, and the tooth break problem is prevented.
Description
Technical field
The present invention relates to a kind of gear, particularly a kind of gear with shock-absorbing function.
Background technique
The gear applied in prior art in retarder does not have shock-damping structure, and retarder in the course of the work, because the engagement between gear exists impact, make noise during gears meshing comparatively large, and the collision taking turns between cog also causes gear to occur breakage problem.
Summary of the invention
In view of this, the object of this invention is to provide a kind of cylindrical gears with shock-damping structure, do not have shock-damping structure to solve gear of the prior art, there is impact during gears meshing between gear, when making gears meshing easily there is the problem of fracture in the comparatively large and gear teeth of noise.
The cylindrical gears of band shock-damping structure of the present invention, comprise inner ring body and outer ring body, the external cylindrical surface of described outer ring body is provided with the gear teeth, the inner cylindrical surface of described outer ring body is evenly arranged groove, the external cylindrical surface of described inner ring body is provided with lobe, described lobe is arranged in groove, and is provided with snubber block in the circumferential gap of lobe and groove.
Further, the end face of described inner ring body is connected by screw the baffle plate preventing outer ring body from coming off vertically.
Further, described inner ring body and outer ring body are made up of powder metallurgy.
Further, described snubber block is polyurethane snubber block.
Beneficial effect of the present invention:
The cylindrical gears of band shock-damping structure of the present invention, it by arranging snubber block between inner ring body and outer ring body, when gears meshing, gear is subject to impulsive load, and now outer ring body just can to snubber block applying pressure along the circumferential direction, snubber block generation resiliently deformable, apparatus with shock absorbing, realizes gear damping, can reduce noise during gears meshing, and can avoid impacting the injury to the gear teeth, avoid occurring broken teeth problem.
Accompanying drawing explanation
Fig. 1 is the structural representation of the cylindrical gears of the present embodiment band shock-damping structure;
Fig. 2 is the structural representation after the cylindrical gears of the present embodiment band shock-damping structure loads onto baffle plate.
Embodiment
Below in conjunction with drawings and Examples, the invention will be further described.
As shown in the figure, the cylindrical gears of the present embodiment band shock-damping structure, comprise inner ring body 1 and outer ring body 2, the external cylindrical surface of described outer ring body is provided with the gear teeth 3, the inner cylindrical surface of described outer ring body is evenly arranged groove, the external cylindrical surface of described inner ring body is provided with lobe 4, described lobe is arranged in groove, and is provided with snubber block 5 in the circumferential gap of lobe and groove.
The cylindrical gears of the present embodiment band shock-damping structure, it by arranging snubber block between inner ring body and outer ring body, when gears meshing, gear is subject to impulsive load, and now outer ring body just can to snubber block applying pressure along the circumferential direction, snubber block generation resiliently deformable, apparatus with shock absorbing, realizes gear damping, can reduce noise during gears meshing, and can avoid impacting the injury to the gear teeth, avoid occurring broken teeth problem.
As the improvement to the present embodiment, the end face of described inner ring body is connected by screw the baffle plate 6 preventing outer ring body from coming off vertically, carries out axial limiting by baffle plate 6 pairs of outer ring bodies, the axial slip of working gear process China and foreign countries ring body can be avoided.
As the improvement to the present embodiment, described inner ring body 1 and outer ring body 2 are made up of powder metallurgy, and easily manufactured, manufacturing efficiency is high.
As the improvement to the present embodiment, described snubber block 5 is polyurethane snubber block, and damping performance is good, long service life.
What finally illustrate is, above embodiment is only in order to illustrate technological scheme of the present invention and unrestricted, although with reference to preferred embodiment to invention has been detailed description, those of ordinary skill in the art is to be understood that, can modify to technological scheme of the present invention or equivalent replacement, and not departing from aim and the scope of technical solution of the present invention, it all should be encompassed in the middle of right of the present invention.
