Embodiment Construction

[0051] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. The following examples are only used to illustrate the present invention, and are not intended to limit the protection scope of the present invention.

[0052] Figure 4 As shown, a method for equal installation and adjustment of the back distance of the band brake, which includes the following steps:

[0053] Travel of the brake band when the brake is released , where: ε——brake opening clearance; α——brake band wrap angle;

[0054] When the brake release stroke and the wrap angle of the brake band are constant, there must be a certain brake opening gap , by adjusting the back distance adjustment device 33, the place where the brake band has a relatively large brake opening distance is pressed to the brake wheel 22, which can effectively prevent the brake band 11 from having too large a brake opening gap, and the deformation of the steel belt...

Abstract

The invention discloses a clearance equalizing device of a belt brake. The clearance equalizing device comprises a brake belt, a brake wheel, clearance adjusters and a mounting support. A mounting support is mounted around the brake belt, and the clearance adjusters are sequentially added on the brake belt from a fixed end to a movable end and are fixed on the mounting support. The invention further discloses a mounting and adjusting method by means of the clearance equalizing device of the belt brake. By adjusting the clearance equalizing device, the brake belt can be limited from opening too large clearance, the brake belt can have a certain opening clearance and normal use of the belt brake is ensured. Without welding and cutting the brake belt and the like, the mounting and adjusting method has no influence on the integral performance of the belt brake and is applicable to mounting and use of various belt brakes.

Description

technical field [0001] The invention relates to a device for equalizing the back distance of a band brake. [0002] The invention also relates to a method for installing and adjusting the back distance of the band brake. In particular, it relates to large hydraulic band brakes, which are mainly used for adjusting the back distance of anchor winches for large ships and band brakes for large hoisting mechanisms. Background technique [0003] Due to the relatively large size of large ships and large hoisting mechanisms and limited installation space, band brakes are often used in this type of products. The two most important performance parameters of large hydraulic band brakes are braking torque and brake opening clearance. The braking torque ensures that the driving mechanism is not driven by external force when it stops, and the opening clearance ensures that the driving mechanism does not rub against the brake band when it is working normally. [0004] According to Euler'...
