Layered roller isolator

Abstract

The utility model relates to an automobile part, in particular to a layered roller isolator which comprises a hollow shaft, a cover cap, a gasket, a guide cylinder, a roller, a flat spring and a cylindrical pin. A riveting groove is formed in the outer circle of the guide cylinder, two layers of same curved surfaces are uniformly distributed in the inner circumferential direction, and a plurality of pin holes are uniformly formed in the bottom end of the guide cylinder in the circumferential direction; the pin roller and the flat spring are both mounted in a space formed by the long end of the hollow shaft and the guide cylinder; the gasket is pressed on the convex shoulder of the hollow shaft and clings to the open end of the guide cylinder; the cover cap is pressed on the outer side of the gasket and is connected with the guide cylinder through riveting; and the plurality of cylindrical pins are respectively arranged in the pin holes of the guide cylinder. The one-way clutch has the advantages that due to the design of the multiple layers of rollers, load pressure can be effectively dispersed, impulsive force can be transmitted more evenly, the rollers are not prone to inclining and being stuck in the working process, and the problem that a traditional one-way clutch is prone to being stuck and slipping is effectively solved.

Description

Technical Field

[0001] This utility model relates to an automotive component, specifically a layered roller one-way valve. Background Technology

[0002] A one-way clutch (also known as a one-way overrunning clutch) is a key component in a transmission system. Its core function is to allow power to be transmitted in one direction and automatically prevent reverse rotation. It works by using rollers between the inner and outer rings to achieve one-way locking, allowing power to be transmitted in one direction while separating in the opposite direction. Traditional one-way clutches typically use a single layer of rollers, which are prone to jamming and slippage when applied to high-power construction machinery and high-load applications such as ships. Summary of the Invention

[0003] To address the aforementioned problems, this invention provides a layered roller one-way valve.

[0004] The technical solution adopted in this utility model is:

[0005] The layered roller one-way device includes a hollow shaft, a cover, a washer, a guide cylinder, rollers, flat springs, and cylindrical pins. The hollow shaft has a shoulder, which divides the hollow shaft into a long end and a short end. The guide cylinder has a riveting groove on its outer circumference and two identical curved surfaces evenly distributed circumferentially inside. Several pin holes are evenly distributed circumferentially at its bottom end. There are several rollers and flat springs, the number of which is twice the number of curved surfaces inside the guide cylinder. The flat springs are installed in the inner curved surfaces of the guide cylinder and contact one side of the inner curved surfaces. The rollers are also installed in the inner curved surfaces of the guide cylinder and contact the other side of the flat springs. The rollers and flat springs are installed in the space formed by the long end of the hollow shaft and the guide cylinder. The washer presses on the shoulder of the hollow shaft and is tightly attached to the open end of the guide cylinder. The cover presses on the outside of the washer and is connected to the guide cylinder by riveting. There are several cylindrical pins, which are respectively installed in the pin holes of the guide cylinder.

[0006] The beneficial effects of this utility model are: through the multi-layer roller design, the load pressure can be effectively distributed, making the impact force transmission more uniform, and the rollers are not easy to tilt or jam during operation, effectively improving the problem of traditional one-way valves being prone to jamming and slipping.

[0011] The layered roller one-way valve includes a hollow shaft 1, a cover 2, a washer 3, a guide cylinder 4, rollers 5, flat springs 6, and cylindrical pins 7. The hollow shaft 1 has a shoulder that divides it into a long end and a short end. The guide cylinder 4 has a riveting groove on its outer circumference and two identical curved surfaces evenly distributed circumferentially inside. Several pin holes are evenly distributed circumferentially at its lower end. There are multiple rollers 5 and flat springs 6, the number of which is twice the number of curved surfaces inside the guide cylinder 4. The flat springs 6 are installed within the internal curved surfaces of the guide cylinder 4. The roller 5 is also installed in the inner curved surface of the guide cylinder 4 and contacts the other side of the flat spring 6. The roller 5 and the flat spring 6 are both installed in the space formed by the long end of the hollow shaft 1 and the guide cylinder 4. The washer 3 is pressed on the shoulder of the hollow shaft 1 and is tightly attached to the open end of the guide cylinder 4. The cover 2 is pressed on the outside of the washer 3 and connected to the guide cylinder 4 by riveting. There are several cylindrical pins 7, which are respectively installed in the pin holes of the guide cylinder 4.
