Embodiment Construction

[0016] The gear of the present invention and the transmission mechanism using the gear will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0017] see Figure 1 to Figure 3 The transmission mechanism 100 of the embodiment of the present invention includes a transmission shaft 20, a first gear 30 and a washer 50 sleeved on the transmission shaft 20, a second gear 40 meshing with the first gear 30, and a second gear 40 that is arranged on the transmission shaft 20 and the first gear. Block 60 between gears 30 .

[0018] The transmission shaft 20 includes a cylindrical main shaft portion 21 and a connecting portion 23 extending from one end of the main shaft portion 21 . The radial dimension of the connection portion 23 is smaller than the dimension of the main shaft portion 21 . A mounting slot 231 for partially accommodating the block 60 is defined on a side surface of the connecting portion 23 , and a first mounting hole ...

Abstract

The invention discloses a gear which comprises an outer gear ring, an inner gear ring and an elastic member, wherein the outer gear ring is provided with a sliding chute; the elastic member is arranged in the sliding chute; a sliding part is formed on the inner gear ring, is inserted into the arc sliding chute of the outer gear ring and is abutted against the elastic member. The gear has the advantages of long service life and high driving precision. The invention also provides a driving mechanism adopting the gear.

Description

technical field [0001] The invention relates to a gear and a transmission mechanism using the gear, in particular to a bevel gear and a transmission mechanism using the bevel gear. Background technique [0002] Gears are widely used in various mechanical transmission mechanisms. The purpose of reducing the output speed can be achieved by arranging multiple gears with different sizes and intermeshing between the input shaft and the output shaft of the transmission mechanism. [0003] A bevel gear, which includes a cylindrical main body and a tooth groove formed by extending outward from one end edge of the main body. A connecting hole is also opened on the main body to connect with the input shaft or the output shaft. When the above-mentioned bevel gear is applied to a transmission structure, the tooth lines of multiple bevel gears mesh with each other. [0004] However, the above-mentioned bevel gears are prone to wear after long-term use, which will cause a gap between tw...
