Abstract
The utility model discloses a fiction coupling relating a coupling, and the utility model aims at providing a fiction coupling having small fiction heat energy and no conglutination. Furthermore, the utility model aims at providing the fiction coupling with good effect of dissipating heat. The technical proposal of the utility model is that the fiction coupling comprises a main driving shaft, an output shaft and a coupling hoop, a needle type bearing is arranged between the output shaft and a main driving shaft hole. Radiating fins are arranged on the external surface of the coupling. The coupling is used for metallurgical and chemical devices.
Description
Technical field:
The utility model relates to a kind of clutch, particularly a kind of friction clutch.
Background technique:
Adopt fluid clutch or centrifugal friction clutch when overload, motor to be protected in the equipment such as mining scraper plate machine, Belt Conveyors.022410643 friction clutcch makes the life-span of clutch bring up to 1-2 month by about 7 days.But, in this patented technology, between main drive shaft and output shaft, be provided with copper sheathing, its objective is coaxality for output shaft and the main drive shaft that guarantees to be provided with internal spline, because main drive shaft is in starting process, main drive shaft will produce friction in rotation and output shaft does not rotate between copper sheathing and the main drive shaft, cause the copper sheathing heating and adhesion, thereby cause its life-span still to fall short of.In addition, in order to reduce the heat that clutch produces, be provided with blade on the land in the clutch hoop to dispelling the heat between clutch hoop and the clutch hoop, owing to be that radiating effect is relatively poor in the clutch hoop.
Summary of the invention:
The purpose of this utility model provides the little and NA friction clutch of a kind of frictional heat.Another purpose of the present utility model provides a kind of friction clutch of good heat dissipation effect.The technical solution of the utility model is, a kind of friction clutch comprises main drive shaft, and output shaft and clutch hoop is characterized in that: be provided with the pin type bearing between output shaft and main transmission axis hole.On the outer surface of clutch hoop, be provided with radiating fin.The utility model has the advantage of adhesion and good heat dissipation effect long service life compared with the prior art.
Description of drawings:
Accompanying drawing is the structural representation of the utility model friction clutch.
Embodiment:
In conjunction with above accompanying drawing the utility model is elaborated, the utility model produces adhesion problems in order to solve the copper sheathing heating, changes the copper sheathing between existing main drive shaft 1 and the output shaft 9 into pin type bearing 8; In addition, in order to improve heat dispersion, radiating fin 7 is set on the outer surface of clutch hoop.
Working principle of the present utility model is, do not reach as yet in the process of certain rotating speed in the main drive shaft starting, and output shaft does not rotate, and the rotation of main drive shaft this moment on the pin type bearing is for rolling, and the heat of its generation is very little, and phenomenon can not stick together.When rotating speed reaches certain rotating speed, the elastic force that the helical teeth of main drive shaft makes friction disk 3 overcome spring 6 leans against friction ring 5 on the internal surface of clutch hoop 2 to having to move, thereby driving output shaft rotates, owing to be evenly equipped with radiating fin on the outer surface of clutch hoop, thereby improved the radiating effect that has only blade 4.When the load on the output shaft surpassed load rating, motor speed descended, and friction ring is thrown off the clutch hoop under the effect of spring, and motor idle running is avoided damaging motor because of overburdening.Because the radiating fin on pin type bearing and the clutch hoop, the life-span of friction clutch of the present utility model is longer.
Claims (2)
1, a kind of friction clutch comprises main drive shaft, and output shaft and clutch hoop is characterized in that: be provided with the pin type bearing between output shaft and main transmission axis hole.
2, friction clutch according to claim 1 is characterized in that: be provided with radiating fin on the outer surface of clutch hoop.
