In the early manual assembly process of the R-EPS steering gear product, the belt tension is required to be manually adjusted to a proper interval, if the belt tension is too large, the abrasion of the belt is increased, if the belt tension is too small, the phenomenon of tooth jump of the belt in the operation process is caused, and if the difference of the two sides of the belt tension is large, the problems of abnormal sound, uneven belt abrasion, incomplete tooth engagement and the like are caused. The problems of irregular assembly of the ball screw belt wheel, jumping of the tooth surface of the belt wheel, tooth inclination and the like are the biggest causes of abnormal tension of the belt.
If the problem arises with the lead screw pulley assembly (the pulley has been assembled to the ball screw nut assembly), the low cost pulley would need to be removed and replaced with a new pulley due to the high cost of the lead screw nut assembly. Because the lead screw nut assembly is possibly damaged in the process of removing the belt wheel, a convenient and quick tool capable of safely removing the belt wheel manually is highly required.

Further, the connecting hole of the clamping plate is in a strip shape.
Further, the tail end of the bending part is provided with an arc-shaped opening.
Further, a buffer gasket is arranged at the tail end of the groove of the screw bolt.
Further, the internal thread is in the opposite direction to the external thread.
The beneficial effects of the utility model are as follows:
1. the scheme provides an operation convenience is high, and the security is high, and the structure is simple relatively, and the practicality is good, does not hinder ball screw nut assembly, is applicable to different R-EPS product steering gears, has solved the difficult problem of extracting of band pulley after the pressure equipment, extracting the damage lead screw.
2. This scheme can be through setting up the cardboard connecting hole into rectangular shape, adapts to the lead screw of multiple different specification length, and the suitability is better.

Detailed Description
Referring to fig. 1, a tool for rapidly removing a ball screw belt pulley comprises a screw 1 and a dismounting sleeve 2, wherein a nut 4 is installed on the screw 1, a belt pulley 3 is assembled on the nut 4, the belt pulley 3 and the nut 4 are integrally pressed together by interference fit, the dismounting sleeve 2 comprises a sleeve 5, one end of the sleeve 5 is provided with an opening, the other end of the sleeve 5 is provided with a threaded hole 6, a screw bolt 7 is assembled in the threaded hole 6, the outer surface of the screw bolt 7 is provided with an external thread 8 matched with the threaded hole 6, the bottom of the screw bolt 7 is provided with a groove 9, an internal thread 10 matched with the screw 1 is arranged in the groove 9, a clamping plate 11 is symmetrically installed on the outer surface of the sleeve 5, one end of the clamping plate 11 is provided with a connecting hole 12, a screw 13 is arranged in the connecting hole 12, the clamping plate 11 is assembled on the sleeve 5 through the screw 13, one end of the clamping plate is provided with a bending part 14, and the direction of the internal thread 10 is opposite to that of the external thread 8.
Referring to fig. 2, a buffer pad 16 is disposed at the end of the groove 9 of the screw bolt 7. The buffer gasket can avoid the end part of the screw rod from being crushed.
Referring to fig. 3, the connecting hole 12 of the clamping plate 11 is in a strip shape, and an arc-shaped opening 15 is provided at the end of the bending portion 14. The elongated shape employed by the attachment holes 12 may allow the card to be compatible with more standard lead screw lengths.
The working principle of the utility model is as follows:
when the pulley 3 is damaged and needs to be disassembled, the screw 1 is firstly taken down integrally, inserted into the sleeve 5 and screwed up by the internal thread 10 in the screw rod 7, and the end part of the screw 1 is contacted with the groove of the screw rod 7. At this time, the bent portion 14 of the clip 11 is placed on the opposite side of the pulley 3. Since the ends of the bent portions are arc-shaped openings 15, the two bent portions form an approximate circle and clamp the outer sides of the pulleys.
At the moment, the screw rod 7 is screwed in the opposite direction, the screw rod 7 is gradually displaced, and the screw rod 1 is ejected outwards; the clamping plate 11 keeps the belt pulley 3 in place through the bending part 14, and the screwing force of screwing the screw column 7 is converted into the axial force of the clamping plate 11 for pulling the belt pulley 3, so that the belt pulley 3 can be pulled out quickly, and the screw rod is not damaged.
Although the present utility model has been described with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described, or equivalents may be substituted for elements thereof, and any modifications, equivalents, improvements and changes may be made without departing from the spirit and principles of the present utility model.
