[ Utility model ] content
The utility model aims at providing a brake clearance adjusting device of reliable, the brake clearance adjustable turn-buckle of braking.
Therefore, the utility model provides a following technical scheme:
the utility model provides a brake clearance adjusting device of turn-buckle, is including installing stopper and the brake nut on the major axis in proper order, and the stopper comprises inner friction piece, ratchet and the outer friction piece that the spline is connected to the stopper seat on the major axis and is in proper order empty cover on the stopper seat, and the brake nut transmission threaded connection is on the major axis, and its improvement lies in: the anti-rotation device is characterized by also comprising a non-return stop block connected to the long shaft through a spline, wherein the non-return stop block is positioned on the outer side of the brake nut, the side wall of the brake nut is provided with a bulge, the installation of the non-return stop block ensures that an installation angle difference exists between the non-return stop block and the bulge, and the bulge of the brake nut can be abutted against and stopped by the non-return stop block after the brake nut rotates back by the installation angle difference; the braking clearance is adjusted by changing the installation angle of the backstop stop block on the long shaft.
The installation angle difference is 40-55 degrees.
The utility model has the advantages of as follows and positive effect:
after the braking nut is additionally provided with the bulge and the retaining stop block is arranged on the long shaft, the braking is reliable, and after two friction plates of the brake are ground to be thin, the braking gap can be adjusted by adjusting the installation angle of the retaining stop block.

[ detailed description ] embodiments
Referring to fig. 1, 2, 3 and 4, a brake clearance adjusting device of a wire tightener comprises a brake 1 and a brake nut 2 which are sequentially arranged on a long shaft 3, wherein the brake 1 consists of a brake seat 10 which is connected with the long shaft 3 through a spline, and an inner friction plate 11, a ratchet wheel 12 and an outer friction plate 13 which are sequentially sleeved on the brake seat 10 in an empty mode, the brake nut 2 is in transmission threaded connection with the long shaft 3, and the improvement point is that: the anti-loosening stop block 4 is connected to the long shaft 3 through a spline, the anti-loosening stop block 4 is located on the outer side of the brake nut 2, a protrusion 21 is arranged on the side wall of the brake nut 2, the anti-loosening stop block 4 is installed to enable an installation angle difference to exist between the anti-loosening stop block 4 and the protrusion 21, and the protrusion 21 of the brake nut 2 can abut against the anti-loosening stop block 4 to be stopped after the brake nut 2 is unscrewed by the installation angle difference; the braking clearance Q is adjusted by changing the installation angle of the backstop block 4 on the long shaft 3.
When the friction plate is worn down to cause the braking clearance Q to be larger than 1mm, the mounting angle difference is increased.
The installation angle difference is controlled between 40 degrees and 55 degrees, please refer to fig. 4, an installation angle difference of 45 degrees is formed between the backstop stop 4 and the protrusion 21, at this time, no gap is formed between the brake nut 2 and the brake 1 (fig. 1), and the braking state is started; when the tightener is in a brake release state, the backstop stop 4 is abutted to the protrusion 21, and a brake gap Q (0.5-1 mm) is formed between the brake nut 2 and the brake 1, as shown in fig. 2.
The outer end face of the brake nut 2 is provided with end teeth 20, which end teeth 20 are in engagement with end teeth 50 provided on the end face of the output planet carrier 5, which output planet carrier 5 is a part of a planetary reduction gear of a known construction (not shown in its entirety).
After the retaining stop 4 is connected with the long shaft 3 through a spline, the retaining stop 4 is positioned in the annular groove 500 of the output planet carrier 5, one side surface of the retaining stop 4 is abutted against the shaft shoulder 31 of the long shaft 3, and the other side surface of the retaining stop 4 is limited through the groove bottom wall of the annular groove 500 of the output planet carrier 5.
Because the retaining stop block 4 is positioned in the annular groove 500, the situation that the shaft ends of the retaining stop block 4 and the long shaft 3 are wetted in rainy days in the process of open-air line tightening operation can be avoided, and the situation that the retaining stop block 4 is rusted on the long shaft 3 to influence the adjustment of the installation angle of the retaining stop block 4 relative to the long shaft 3 is avoided.
