Abstract

The utility model relates to a clutch device which is used for feeding material to a flour mill and milling flour. Figure 1 shows that the main body of the utility model comprises an oil cup 1, a clutch wheel 2, a clutch outer sleeve 3, a spring 4, a flat key 5, an axis circlip 6, a spring seat 7, a clutch inner sleeve 8, a toggle sleeve support seat 9, a toggle sleeve 10 and a dosing roller 11. A V-shaped belt is driven by an electric motor so that main dynamic force is passed to the clutch wheel 2 which is fixedly connected with the clutch outer sleeve 3 through a bolt. The dosing roller 11 is sheathed in the clutch wheel 2 and in the clutch outer sleeve 3, the clutch inner sleeve 8 and the spring seat 7 are movably arranged on the dosing roller 11 through the flat key 5, and the spring seat 7 is fixed to the dosing roller 11 through the axis circlip 6. The spring 4 is arranged between the spring seat 7 and the clutch inner sleeve 8, one end of the clutch outer sleeve 3 and one end of the clutch inner sleeve 8 form a connection mode like a cone hole and cone body, the dosing roller 11 is also provided with the toggle sleeve support seat 9, and the toggle sleeve 10 is arranged on the toggle sleeve support seat 9 through pins. The clutch inner sleeve 8 is pushed through the movement of the toggle sleeve 10 so as to enable the clutch inner sleeve 8 to do reciprocating movement under the combined action of both the toggle sleeve 10 and the spring 4. A clutch part is separated according to the structure of the cone hole so that the purpose of the clutch of a flour mill is achieved.

Description

A kind of engaging and disengaging gear of milling machine

Technical field

The utility model relates to a kind of engaging and disengaging gear that milling machine is carried out feeding and uses when grinding, and is called for short engaging and disengaging gear hereinafter.

Technical background

Engaging and disengaging gear of the prior art adopts gear transmission clutch, cat's paw's clutch and mechanical friction clutch usually, and its outstanding shortcoming is: gear transmission clutch noise is big, and greasy dirt is serious; Cat's paw's clutch is easy to wear, operates dumb; Mechanical friction clutch processing cost and cost of production height keep in repair loaded down with trivial details.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art and a kind of clutch flexible and convenient operation, engaging and disengaging gear easy to maintenance is provided.

The purpose of this utility model is achieved in that active force is delivered to clutch wheel by motor and V-belt, clutch outer is fixed on the clutch wheel, be sleeved in clutch wheel and the clutch outer doctor roll is arranged, on doctor roll, be movably installed with clutch inner sleeve by flat key, it between clutch outer and the clutch inner sleeve Placement of a kind of taper hole and cone, with jump ring spring seat is installed by axle, between clutch inner sleeve and spring seat, spring is installed, to should taper hole and cone, the sliding set bearing is installed on doctor roll, sliding set by dowel fixes on the sliding set bearing.

Embodiment

As shown in Figure 1, the utility model main body comprises lubricating cup 1, clutch wheel 2, clutch outer 3, spring 4, flat key 5, axle jump ring 6, spring seat 7, clutch inner sleeve 8, sliding set bearing 9, sliding set 10, doctor roll 11.

Active force is by the motor drives V-belt, pass to clutch wheel 2, be bolted to connection between clutch wheel 2 and the clutch outer 3, doctor roll 11 is sleeved in clutch wheel 2 and the clutch outer 3, on doctor roll 11, be movably installed with clutch inner sleeve 8 and spring seat 7 by flat key 5, spring seat 7 is fixed on the doctor roll 11 with jump ring 6 by axle, between spring seat 7 and the clutch inner sleeve 8 spring 4 is installed, between one of one of clutch outer 3 and clutch inner sleeve 8 is the Placement of a kind of taper hole and cone, sliding set bearing 9 also is installed on doctor roll 11, and sliding set 10 is installed on the sliding set bearing 9 by pin; By moving of sliding set 10, promote clutch inner sleeve 8, clutch inner sleeve 8 is moved back and forth under the acting in conjunction of sliding set 10 and spring 4, establish the separation of clutch part by the taper hole structure, thereby reach the clutch purpose of milling machine.

This use is novel, and to have a noise little, and no greasy dirt operates steadily, and is simple to operate, easy to maintenance, and low cost and other advantages is fit to vast milling machine manufacturing enterprise and promotes the use of.
