limited torque overrunning clutch

Abstract

The invention provides a twisting-limited overrun clutch and relates to the technical field of mechanical transmission basic pieces in an electromechanical integrated product. The twisting-limited overrun clutch specifically comprises an inner ring (1), a wedged fastening piece (2), gaskets (3), shaft stops (4), sealing pieces (5), an outer ring (6), friction sheets (7), a flange pressure plate (8), a supporting sleeve (10), sealing rings (9), a cylindrical pressure spring (11), an adjustment bolt (12), an end cover (13), a protection cover (16), a releasing bolt (17), a base plate (19), disc springs (20), a screw (15) and an insertion pin (14), wherein two end faces of the outer ring (6) are connected with the flange pressure plate (8) and the supporting sleeve (10) by the friction sheets through loading of the adjustment bolt and the cylindrical pressure spring. The twisting-limited overrun clutch has all the functions of the conventional overrun clutch, has a twisting limiter overload safety reliable protection transmission piece and a torque balance function, is low in energy consumption and can effectively avoid severe accidents such as turning over of high-speed vehicles.

Description

technical field [0001] The invention relates to the technical field of mechanical transmission basic components in electromechanical integration products, in particular to a torque-limiting overrunning clutch. Background technique [0002] The overrunning clutch is an important basic part of the power transmission between the prime mover and the working machine or between the driving shaft and the driven shaft inside the machine for engaging and separating functions. With the development of modern science and technology, the application fields are constantly expanding. The operating conditions are more complicated and severe, especially the sudden overload or impact will cause damage to the overrunning device and cause failure of the transmission system. Due to the rapid development and application of high-power, large-inclination, and long-distance belt conveyors in recent years, a multi-drive method is adopted to install overrunning clutches (backstops) in each drive unit...

Problems solved by technology

The working conditions are more complicated and harsh, especially the sudden overload or impact will cause damage to the overrunning device and cause failure of the transmission system

Due to the rapid development and application of high-power, large-inclination, and long-distance belt conveyors in recent years, a multi-drive method is adopted to install overrunning clutches (backstops) in each drive unit accordingly. The clutch is affected by the manufacturing and installation errors, torsional rigidity and running wear of each component, so that a certain overrunning clutch may bear most or even all of the backstop torque when performing backstop action, resulting in overrunning clutch or transmission system. If the shaft is damaged, it will cause a major accident of reverse speeding

Although a large safety factor was selected in the design, the safety margin of the overrunning clutch installed in each unit of the multi-drive was enlarged, and the measure of "big horse-drawn cart" was adopted to increase energy consumption and equipment cost, but It is not possible to prevent the occurrence of such accidents
