Description

Improved slip gear set

The present invention provides an improved slip-off gear set, and more particularly to an improved slip-off gear set having a larger contact area of the tooth block and a more evenly distributed force.

The driving gear set is disposed between a driving component and a passive component, and the kinetic energy transmitted by the driving component is transmitted to the passive component through the driving gear set, and the driving gear set has the function of connecting the driving component and the passive component. Alternatively, as a function of shifting or decelerating braking, as shown in FIGS. 6 and 7, a driving gear set 90 having a starting deceleration function is disclosed. The driving gear set 90 includes a body 91, a plurality of gear rings 92 and a plurality of washers 93. The gear ring 92 is sleeved on the body 91. The outer periphery of the gear ring 92 forms a plurality of spaced-apart tooth blocks 94. The outer periphery of the tooth blocks 94 form an engaging surface 95. The washers 93 are spaced apart. The gear sleeve 92 is disposed on the body 91 and is staggered with the gear rings 92. When a driving member (not shown) drives the gear rings 92 to rotate, the body 91 is rotated, and the gear rings 92 pass through the washers. 93, the rotation torque is broken, and the effect of deceleration slippage and no power transmission is achieved.

However, the existing gear ring 92 and the washers 93 are staggered such that the gap between the tooth blocks 94 of the gear rings 92 is enlarged, and the gaps cause the engagement faces of the tooth blocks 94 of the gear rings 92. The contact area of the teeth 95 is reduced. The smaller the contact area of the engaging surfaces 95 of the teeth 94 is, the more easily the teeth 94 are worn or scratched, and even the engaging surface 95 of the teeth 94 is forced to exceed the load. The breakage aggravates the wear of the blocks 94, causing the teeth 94 to collapse.

The main purpose of the present invention is to provide an improved slip-off gear set, whereby the meshing surface area of the tooth block of the existing gear ring is limited by the gap between the gear rings, causing the tooth block to be easily worn, scratched or chipped. The problem.

In order to achieve the previous goals, the improved slip-off gear set of this creation includes:  a body comprising a mandrel, a tooth set and an outer ring clamp, the tooth set being disposed at one end of the mandrel, the outer ring clamp being clamped at the other end of the mandrel;  a plurality of gear units, the gear units are sleeved on the mandrel, each gear unit includes a gear ring and a washer, and the gear rings are sleeved on the mandrel, and the outer periphery of the gear rings A plurality of spaced-apart blocks are formed, and a groove is formed on the inner side of the gear rings, and the washers are sleeve-arranged on the mandrel, and the washers are located in the grooves of the gear rings.  

The modified slip-off gear set of the present invention forms the grooves by the inner sides of the gear rings, and the gear rings are transmitted when a driving member drives the gear rings to rotate and rotate the mandrel. The washers have the effect of decelerating the rotational moment to achieve the deceleration, and the gap between the tooth blocks of the gear rings becomes smaller, the contact area of the tooth blocks that can be engaged becomes larger, and the teeth are evenly dispersed. The force received makes the blocks less likely to break, and the strength of use of the blocks is also extended to extend the service life of the blocks.
