CS244508B1 - Electromagnetic clutch - Google Patents

Abstract

Solution ee concerns an electromagnetic clutch of a shuttle lifting carriage of a weaving loom, equipped with a program control. The task is to create an electromagnetic clutch for high-speed machines. The task is solved in the following way: a roller is inserted into the channel of the grooved eccentric, set in motion by the shaft of the shuttle lifting carriage, pressing the free end of the single-arm levers. In turn, they fit into the upper, fork-shaped end of the securing levers, which are axially movable in bearings on the guide rails. A groove is provided in the securing levers, into which the armature of a fixed electromagnet is guided. This electromagnet is attached to the aforementioned guide rail, in which a gap is provided through which the armature of the electromagnet freely passes. The advantage is the use of low-power electromagnets.

Description

(54) Electromagnetic clutch

The solution ee relates to an electromagnetic clutch of a weaving loom equipped with a program control.

The task is to create an electromagnetic clutch for high-speed machines.

The problem is solved as follows: the channel of the groove eccentric which is moved by the shaft of the pawl hoist includes a roller pressing the free end of the single-arm levers. From their side, they engage the upper, modified end, in the form of a fork of the locking levers, which are axially movable in bearings on the guide rails.

A groove is provided in the locking levers into which the anchor of the fixed electro magnet is guided. The electromagnet is mounted on said guide rail, in which a gap is provided, through which the armature of the electromagnet is freely passed.

The advantage is the use of low power electromagnets.

Claims (3)

I will invent the subject An electromagnetic clutch for a pawl lift truck, comprising an eccentric locking lever actuated by an eccentric, characterized in that the armature (10, 10 *) of the fixed magnet (11, 11 *) points towards a groove (7, 7 *) disposed axially in bearings on the guide bar (4, 4 *) of the locking lever (12, 12 *) of the driving eccentric. Electromagnetic clutch according to claim 1, characterized in that the guide rail (4, 4 *) opposite the groove (7, 7 *) has a gap (8, 8 *). An electromegnetic clutch according to claim 1, characterized in that at the upper end of the locking lever (12, 12 ') there is provided a fork (6, 6') in which the end of the single-arm lever (9, 9 *) is pressed. 1), moved by an eccentric. Recognized by the invention based on the results of expertise carried out by the Institute of Invention and Improvement, Sofia, BG.
