Embodiment Construction

[0013] Specific embodiments of the present invention will be further described in detail below. It should be understood that the description of the embodiments of the present invention here is not intended to limit the protection scope of the present invention.

[0014] like Figure 1 to Figure 2 As shown, it is a structural schematic diagram of a low-vibration silent gear provided by the present invention. The low-vibration silent gear includes a gear main body 10 and a plurality of teeth 20 arranged on the gear main body 10. The low-vibration silent gear also includes other functional modules, such as shaft connection holes and shaft connection grooves etc., which should be known to those skilled in the art, and will not be described in detail here.

[0015] The gear main body 10 is used for connecting and fixing with an external rotating shaft (not shown in the figure), and carries teeth 20 arranged on its peripheral outer wall.

[0016] The tooth 20 includes a tooth top...

Abstract

A low-vibration mute gear comprises a gear body and teeth arranged on the gear body. Each tooth comprises a tooth top, a tooth end surface and a tooth root. The other end of each tooth root is connected with the gear body. The end surface of each tooth top is in a circular arc shape. Arc transition is arranged between each tooth root and the gear body. According to the low-vibration mute gear, convex-to-convex contact of involute teeth of an existing gear is changed into convex-to-concave contact, and the contact area between the low-vibration mute gears is increased. According to the low-vibration mute gear, due to the arc design of the tooth tops and the tooth roots and the tooth end surfaces which play a transition role before the tooth tops and the tooth roots are connected, when the low-vibration mute gears mesh with each other, the oil trapping phenomenon between the tooth surfaces is eliminated, and the possibility that noise is formed due to oil trapping between the tooth surfaces is avoided at the primary position. The low-vibration mute gear is more stable in the working process, the generated noise is low, and the health of operators is better protected.

Description

technical field [0001] The invention relates to the technical field of gears, in particular to a low-vibration silent gear. Background technique [0002] A gear is a mechanical element with teeth on the rim that continuously mesh to transmit motion and power. When the gears are meshing, there is a certain gap between the teeth of the two gears, which is called backlash. The existence of the backlash is to reduce the loss of mechanical efficiency during the operation of the gears. However, due to the existence of backlash, during the operation of the gears, the contacting tooth surfaces of the two gears will collide, resulting in a large noise. . Contents of the invention [0003] In view of this, the present invention provides a low-vibration silent gear that can greatly reduce the noise generated by gear meshing, so as to meet industrial needs. [0004] A low-vibration silent gear, which includes a gear body, and a plurality of teeth arranged on the gear body, the teet...
