Problems solved by technology
[0002] The electromagnetic caliper disc brakes currently used do not have a stepless automatic compensation device, which has the following shortcomings: (1) Increased labor intensity of user maintenance personnel
Because the brake friction plate wears steplessly to a certain design value, manual adjustments are not made in time, which will lead to ineffective braking of the brake, which seriously threatens the safety of lifting and transportation machinery
(2) Discontinuous constant brake clamping force
Therefore, the braking force of the newly adjusted brake is relatively large, and with the stepless wear of the friction lining, the braking force also decreases steplessly

The invention discloses a stepless automatic compensating device applied to an electromagnetic clamp disk brake. The stepless automatic compensating device is connected with a spring pull rod; the spring pull rod is driven by an electromagnet; the outer side of the stepless automatic compensating device is provided with a shell; a pair of jacking blocks is arranged in the shell; the outer sides of the jacking blocks are in inclined surface structures; a threaded post extends from the inner side of each of the pair of jacking blocks to the central direction; the two threaded posts are matched with internal threads of inner sleeves; single-direction bearings are used for driving the inner sleeves to rotate after rotating; and the inner sleeves are used for driving the two threaded posts to move outwards by rotating for increasing the distance between the two jacking blocks, so that the problem of increase in the distance between two braking arms caused by wear of a friction plate is solved. The electromagnetic clamp disk brake provided by the technical scheme of the invention is provided with the stepless automatic compensating device, so that the brake is free from maintenance, the labor intensity of maintenance personnel is lowered, and the automation degree of equipment is increased.
Description
technical field [0001] The invention relates to a stepless automatic compensation device, in particular to a stepless automatic compensation device used on an electromagnetic caliper disc brake. Background technique [0002] The currently used electromagnetic caliper disc brake has no stepless automatic compensation device, which has the following disadvantages: (1) The labor intensity of the maintenance personnel of the user is increased. Because when the brake friction plate wears steplessly to a certain design value, manual adjustment is not performed in time, which will lead to ineffective braking of the brake, which seriously threatens the safety of lifting and transportation machinery. (2) Discontinuous and constant brake clamping force. When designing the brake, it is necessary to consider the release of the brake spring caused by the wear of the friction plate. Therefore, the braking force of the newly adjusted brake is relatively large, and with the stepless wear ...
