Embodiment Construction

[0008] As shown in the figure, a friction clutch with overload protection includes a housing part 1, an output shaft 7, a bearing 14, a friction pair, a slotted ring 11, a ball 12, a thrust bearing 9, and a compression device. The housing part 1 is installed on the output shaft 7 through the bearing 14. The housing part 1 is provided with a slotted ferrule 11. The slotted ferrule 11 can rotate synchronously with the housing part 1 under the drive of the housing part 1. At the same time, it can Move in the axial direction; the friction pair includes the outer friction plate 3 arranged in the slotted ring 11 and the inner friction plate 4 arranged on the output shaft 7, the outer friction plate 3 and the inner friction plate 4 are multi-piece and Arranged in a staggered manner; the slotted ferrule 11 is provided with a radial tapered groove, the housing part 1 is provided with a semicircular groove inside, and the ball 12 is arranged in the space formed by the semicircular groove...

Abstract

The invention relates to a friction clutch with an overload protection function. The friction clutch comprises a shell component, an output shaft, a friction pair, a slotted ring, balls, a thrust bearing and a compressor unit. The shell component is installed on the output shaft, and internally provided with the slotted ring, and the friction pair comprises an outer friction lining arranged in the slotted ring, and an inner friction lining arranged on the output shaft; the slotted ring is provided with a radial tapered slot, and the shell component is internally provided with a semicircular slot; the balls are arranged in a space formed by the semicircular slot and the tapered slot; and an outer spring seat of the compressor unit is installed on the output shaft through steps, and an inner spring seat comes into contact with the friction pair, and is installed on the slotted ring through the thrust bearing. According to the friction clutch provided by the invention, the slotted ring and the compressor unit are arranged, so that the friction pair can be separated in work of the friction clutch, and dry friction is avoided when the friction linings slide; and the effective protection is achieved in case of overload, and the service life of the clutch is prolonged.

Description

technical field [0001] The patent of the present invention relates to a friction clutch, especially a friction clutch with overload protection. Background technique [0002] The friction clutch is a clutch that transmits power by the friction torque between the friction plates. When the torque received by the clutch is greater than its own friction torque, the friction plates will slip and the clutch will disengage to realize its clutch function. The general friction clutch realizes the clutch only through the friction torque between the friction plates, which will reduce the service life of the friction plates. Contents of the invention [0003] The patent of the invention relates to a friction clutch with overload protection, which reduces dry grinding when the friction plate slips and improves the service life of the clutch. [0004] The specific technical solution of the present invention is: the friction clutch includes housing parts, output shafts, bearings, frictio...
