Abstract
The utility model belongs to the technical field of the drive gear technique and specifically relates to a gear of making an uproar falls in abnormal shape. It includes wheel body, denticle and shaft hole, and denticle evenly distributed is on the circumference of wheel body, and the shaft hole is located the centre of a circle of wheel body, and the denticle comprises two braces, is equipped with spout and roller on the braces, is equipped with the spring in the spout, is equipped with the sheath on the roller. The during operation, supporting gear only contacts with the roller, and the area of contact that has significantly reduced has reduced the friction to sheath through the rubber material carries out rolling contact, has further reduced the resistance, reduces friction, simultaneously, can automatic radial burst when the roller receives pressure and contract, and under the effect of spring with supporting gear in close contact with, the absorption impact force can be cushioned again to the circumference transmission that can guarantee power, effectively plays the effect of making an uproar of falling.
Description
Technical field
The utility model relates to driving gear technical field, especially a kind of special-shaped Noise-reducing gear.
Background technique
Gear is a kind of common mechanical transmission part, is widely used in each mechanical transmission fields.But existing gear is formed primarily of wheel body and denticle, and structure is similar, during work, area of contact is large, and frictional force is also large, in transmission process, because the result of many factors comprehensive function produces noise, is difficult to fundamentally eliminate or reduce.
Model utility content
Large in order to overcome existing tooth contact area, frictional force is large, and be difficult to the deficiency of noise reduction, the utility model provides a kind of special-shaped Noise-reducing gear.
The utility model solves the technological scheme that its technical problem adopts: a kind of special-shaped Noise-reducing gear, comprise wheel body, denticle and axis hole, denticle is evenly distributed on wheel body circumferentially, axis hole is positioned at the center of circle of wheel body, denticle is made up of two braces, braces is provided with chute and roller, is provided with spring in chute, and roller is provided with sheath.
According to another embodiment of the present utility model, comprise roller frame further and be contained between two braces, the two ends of roller are slidably connected in chute.
According to another embodiment of the present utility model, comprising sheath is further rubber sleeve, is wrapped on the outer wall of roller.
According to another embodiment of the present utility model, comprise spring further and be embedded in chute, withstand on the bottom of roller.
The beneficial effects of the utility model are, denticle are designed to the composite structure of two braces, and braces is provided with chute and roller, be provided with spring in chute, roller is provided with sheath, and roller frame is contained between two braces, be slidably connected in chute, be pressed on spring, form rolling engaging mechanism.During work, associated gear only contacts with roller, greatly reduces area of contact, reduce friction, and carry out Structure deformation by the sheath of quality of rubber materials, further reduce resistance, reduce friction, simultaneously, can automatic radial crumple when roller is under pressure, and under the action of the spring with associated gear close contact, the circumference transmission of power can be ensured, again can snubber impact force, effectively play Noise Reduction.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
1. wheel bodys, 2. denticle, 3. axis hole, 4. braces, 5. chute, 6. roller, 7. spring, 8. sheath in figure.
Embodiment
If Fig. 1 is structural representation of the present utility model, a kind of special-shaped Noise-reducing gear, comprise wheel body 1, denticle 2 and axis hole 3, denticle 2 is evenly distributed on wheel body 1 circumferentially, axis hole 3 is positioned at the center of circle of wheel body 1, and denticle 2 is made up of two braces 4, and braces 4 is provided with chute 5 and roller 6, be provided with spring 7 in chute 5, roller 6 is provided with sheath 8.Roller 6 frame is contained between two braces 4, and the two ends of roller 6 are slidably connected in chute 5.Sheath 8 is rubber sleeve, is wrapped on the outer wall of roller 6.Spring 7 is embedded in chute 5, withstands on the bottom of roller 6.
Denticle 2 is designed to the composite structure of two braces 4, braces 4 is provided with chute 5 and roller 6, is provided with spring 7 in chute 5, roller 6 is provided with sheath 8, and roller 6 frame is contained between two braces 4, is slidably connected in chute 5, be pressed on spring 7, form rolling engaging mechanism.During work, associated gear only contacts with roller 6, greatly reduces area of contact, reduce friction, and carry out Structure deformation by the sheath 8 of quality of rubber materials, further reduce resistance, reduce friction, simultaneously, can automatic radial crumple when roller 6 is under pressure, and under the effect of spring 7 with associated gear close contact, the circumference transmission of power can be ensured, again can snubber impact force, effectively play Noise Reduction.
