Description

TECHNICAL FIELD

[0002] As a key component in mechanical transmission system, shaft sleeve is widely used in connecting shaft and bearing, gear and other components, and its core function is to transmit torque, bear load and ensure transmission accuracy. However, the traditional shaft sleeve structure has the following technical bottlenecks in the process of design and application:

[0003] (1) Low torque transmission efficiency, traditional shaft sleeve adopts circular hole design, which is easy to produce sliding friction when matched with non-circular cross section of shaft, resulting in low torque transmission efficiency. Especially under high speed or high load working condition, the relative sliding between shaft and shaft sleeve not only accelerates the wear of contact surface, but also causes transmission error, affecting the stability of equipment operation.

[0004] (2) Heavy structure and low material utilization rate, in order to meet the strength requirement, the existing shaft sleeve often adopts solid or simple slot design, which leads to large weight. At the same time, the use of redundant materials increases the manufacturing cost, and the heat dissipation performance is insufficient, which affects the service life due to heat accumulation.

[0005] (3) Insufficient positioning and limiting mechanism, most shaft sleeves lack multi-stage limiting design, and only rely on single matching surface or fastener fixing. Under the vibration or impact load, axial displacement or circumferential deflection is easy to occur, which reduces the transmission accuracy and even causes equipment failure.

[0006] In view of the above problems, a new type of shaft sleeve structure is needed, which can realize lightweight design under the premise of ensuring mechanical properties, and improve the torque transmission efficiency and positioning stability. INVENTION CONTENTS

[0010] Further, the first inclined inter-rib and the second inclined inter-rib are radially symmetrical about the first straight inter-rib, and the first inclined inter-rib and the second inclined inter-rib are radially symmetrical about the second straight inter-rib.

[0011] Further, the hollowed-out grooves on the two end faces of the shaft sleeve body are not mutually communicated.

[0012] Further, the hollowed-out structure is provided with five groups.

[0013] Further, the polygonal hole is an octagonal hole.

[0014] Further, the outer side of the two end faces of the shaft sleeve body is provided with an outer protruding ring.

[0017] 2. Precise positioning and high stability: the multi-stage limiting mechanism of the limiting groove, the protruding block and the outer protruding ring is combined with the asymmetric torque transmission of the octagonal hole, so that the shaft sleeve is effectively prevented from deviating or slipping in operation, and the transmission precision is ensured.

[0018] 3. Modularity and maintenance convenience: the detachable connection design of the lower base and the upper ring seat makes the shaft sleeve replacement and maintenance not need to disassemble the overall structure, and greatly reduces the downtime and labor cost.

[0019] 4.
