AI Technical Summary
The structural design of traditional unidirectional devices is complicated and complex, and they need to be fully sliding when starting, resulting in high costs and high failure rates.
A unidirectional device for slidable driving gear is designed, including a sleeve, a flat spring, a roller, a washer, a cover, a spline shaft, a drive gear and a self-lubricating bushing. The separation and starting of the unidirectional device is achieved through the sliding and punching of the drive gear.
A simple and compact design of the unidirectional device reduces cost and failure rates while being equipped with traditional starters.

Abstract
Description
Technical Field
[0001] The utility model relates to a driving mechanism, in particular to a one-way device capable of slidably driving a gear. Background Art
[0002] The structure of a traditional one-way clutch consists of two parts: a reduction mechanism and a one-way clutch. During starting, the one-way clutch is slid out as a whole, which makes the design complicated and costly. Summary of the invention
[0003] In order to solve the above problems, the utility model provides a one-way device capable of slidably driving a gear.
[0004] The technical solution adopted by the utility model is:
[0005] The one-way device of the slidable driving gear comprises a flower sleeve, a flat spring, a roller, a washer, a cover, a spline shaft, a driving gear and a self-lubricating bushing; a plurality of wedge-shaped ramps are arranged inside the flower sleeve, and a positioning boss is arranged in the middle; there are a plurality of flat springs and rollers; the number of the flat springs and the rollers is the same as the number of the wedge-shaped ramps; one flat spring and one roller form a group, which are installed on each wedge-shaped ramp and arranged alternately; a positioning hole is arranged at the large end of the spline shaft, and an external spline is arranged in the middle , an outer cylinder is provided at the small end; the large end of the spline shaft is installed in the circular hole surrounded by the flat spring and the roller, and the positioning hole cooperates with the positioning boss; the gasket is installed in the cover; the cover passes through the spline shaft and is fixed to the spline sleeve by riveting; the driving gear is a hollow structure, provided with an inner spline hole, a fork groove and a spur gear; the driving gear is sleeved on the spline shaft, and the inner spline hole cooperates with the outer spline; the self-lubricating bushing is installed in the hole at the end of the spur gear.
[0006] The utility model has the beneficial effect that when using a one-way device with a slidable driving gear, the one-way device can be separated and started by only sliding the driving gear out and in. The structure is simple and compact, low in cost, and low in failure rate, and can be equipped with a traditional starter. BRIEF DESCRIPTION OF THE DRAWINGS
