Description

A kind of electric clutch

Affiliated technical field

The utility model relates to a kind of clutch, specifically a kind of clutch by motor control that transmits large torque.

Background technique

Clutch is widely used in various machineries, the vehicular field, and the form of clutch also has multiple.Divide with control type, mechanical control, pneumatic control, electronic control etc. are arranged.In the clutch of electronic control, the most common with magnetic clutch control.But the torque that this magnetic clutch transmits is smaller.If make it transmit big torque, must add high-powerly, opening and closing during frequent clutch uses, there is tangible deficiency.With the motor is the electric clutch of power source, although can solve above-mentioned deficiency, most complex structures are made difficulty is installed.The relatively simple electric clutch of certain structures often is difficult to transmit big torque.

Summary of the invention

In order to overcome the deficiency that existing clutch exists, the purpose of this utility model provide transmit in the machineries such as can being widely used in building materials (system green brick machine), mine, metallurgy, building large torque, consumed power is little, have a kind of electric clutch simple in structure.

The technological scheme that its technical problem that solves the utility model adopts is: this electric clutch, comprise motor, clutch shaft and by the belt pulley of bearing fixing on clutch shaft, and the inside on the left of belt pulley is provided with by quiet dish seat, quiet disc, the grinding disk that the Moving plate wearing piece is formed, quiet dish cover for seat dress is fixed on the clutch shaft, be provided with the bearing support of band bearing cap at the other end of clutch shaft, mainly be that axle head at motor is provided with driving pinion, on the clutch shaft in belt pulley left side, be provided with by cartridge housing and be fixed on gearwheel and outside thread body on the cartridge housing, the motor control mechanism that the dynamic pressure dish is formed, gearwheel on the cartridge housing is meshed with driving pinion, cartridge housing left end endoporus is provided with internal thread and is connected by internal thread and the outside thread body that is fixed on the bearing support, rotates driving pinion the cartridge housing front and back are moved axially; The dynamic pressure dish endwisely slips by key pin and is sleeved on the clutch shaft, and its left end is provided with bearings mounted bulge loop platform, between the bulge loop platform on cartridge housing and the dynamic pressure dish bearing is installed, and the cartridge housing right-hand member is provided with the dynamic pressure dish and moves axially the gland that cooperates; Fix a circular limit switch on the excircle of cartridge housing left end, annulus is provided with annular groove, is provided with switch arm in the annular groove; The thickness of said driving pinion is 1.1～3 times of gearwheel thickness.

The utility model advantage compared with prior art mainly is with the transmission of less power consumpiton realization than large torque; Simultaneously, it is simple in structure, reliable performance, and the cost of manufacturing is low, uses easy to maintenance.
