Description

Synchronous displacement free clutch gear set

Technical Field

The utility model relates to a gear field specifically is a synchronous displacement free clutch gear group.

Background

Most of the traditional gear sets are locked and fixed after being meshed with each other, and cannot be freely clutched and synchronously displaced. Intermittent transmission is often required in the operation of some equipment, and at the moment, a free clutch gear set is required to transmit power in a combined state and lose power in a separated state; sometimes, in order to achieve reciprocating motion, the gear set also needs to synchronously reciprocate back and forth, which cannot be achieved by the traditional gear set, most of the traditional gear sets can only be meshed with each other to synchronously rotate in a radial direction, and cannot be meshed with each other to synchronously translate in an axial direction, so that the defects are objective.

Therefore, a gear set capable of both synchronous displacement and free-wheeling operation is needed to solve the above problems.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a synchronous displacement free clutch gear group, including driving gear and driven gear, add a pair of lug at the bilateral symmetry of driving gear, form trapezoidal recess with the driving gear card in the middle of, supply driven gear to insert the meshing, reach not only can synchronous axial displacement but also can free clutch synchronous operation's beneficial effect.

In order to solve the above problem, the utility model provides a following technical scheme:

a synchronous displacement free clutch gear set comprises a driving gear and a driven gear;

the center of the driving gear is axially provided with a first round hole, a circle of a plurality of first teeth are regularly arranged on the periphery of the driving gear, a pair of convex blocks with the diameter larger than that of the first teeth are symmetrically and fixedly arranged on two sides of the first teeth, the inner side walls of the convex blocks are inclined planes which are slightly opened from the center to the outer edge, and an inverted trapezoidal annular groove is formed by the inner side walls of the convex blocks and the periphery of the first teeth in the middle;

a through hole with the same size as the first round hole in the center of the driving gear is formed in the center of the pair of the convex blocks;

the center of the driven gear is axially provided with a second round hole, a circle of a plurality of second teeth are regularly arranged on the periphery of the driven gear, and the width of each second tooth is slightly smaller than that of each first tooth.

Compared with the prior art, the utility model has the advantages of it is following:

the utility model relates to a synchronous displacement free clutch gear group, including driving gear and driven gear, add a pair of lug at the bilateral symmetry of driving gear, form trapezoidal recess with the driving gear card in the centre, supply driven gear to insert the meshing, reach not only can synchronous axial displacement but also can free clutch synchronous moving's beneficial effect.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

The specific embodiment is as follows:

in this embodiment, as shown in fig. 1, a synchronous displacement free-clutch gear set includes a driving gear 2 and a driven gear 1;

a first round hole 22 is axially formed in the center of the driving gear 2, a circle of a plurality of first teeth 23 are regularly arranged on the periphery of the driving gear, a pair of protrusions 21 with the diameter larger than that of the first teeth 23 are symmetrically and fixedly arranged on two sides of the plurality of first teeth 23, the inner side walls of the pair of protrusions 21 are inclined planes 24 which are slightly opened from the center to the outer edge, and an inverted trapezoidal annular groove is formed on the periphery of the first teeth 23 in the middle of the protrusions; and a groove with a narrow inner part and a wide outer part is formed, so that the driven gear 1 can be conveniently guided to be inserted or separated, and meanwhile, the driven gear 1 can be driven to synchronously axially displace.

A through hole with the same size as the first round hole 22 at the center of the driving gear 2 is arranged at the center of the pair of convex blocks 21 and is used for penetrating the main shaft;

the central axis of the driven gear 1 is provided with a second round hole 12, a circle of a plurality of second teeth 11 are regularly arranged on the periphery of the driven gear 1, the width of each second tooth 11 is slightly smaller than that of the corresponding first tooth 23, and therefore the plurality of second teeth 11 of the driven gear 1 can be easily inserted into the driving gear 2 to be meshed or separated.

Compared with the prior art, the utility model has the advantages of it is following:

the utility model relates to a synchronous displacement free clutch gear group, including driving gear and driven gear, add a pair of lug at the bilateral symmetry of driving gear, form trapezoidal recess with the driving gear card in the centre, supply driven gear to insert the meshing, reach not only can synchronous axial displacement but also can free clutch synchronous moving beneficial effect, embody novelty, creativity and practicality.

Finally, it should be noted that: the specific embodiments described herein are merely illustrative of the spirit of the invention and do not limit the embodiments of the invention. Various modifications, additions and substitutions for the specific embodiments described herein will occur to those skilled in the art without necessarily requiring or implying any complete departure from all embodiments. Rather, these obvious variations and modifications fall within the spirit of the invention, which is to be construed as being in any way contrary to the spirit of the invention.
