Problems solved by technology
[0004] The problem to be solved by the present invention is: the structure of the existing belt installation tool is relatively complicated
[0005] Another problem to be solved by the present invention is: when using the existing belt installation tool to install the belt, there will be a problem that the belt will come out and the belt will come out, resulting in low installation efficiency
[0006] Another problem to be solved by the present invention is: when using the existing belt installation tool to install the belt, the belt will cross the groove and cause the belt to be damaged.

Embodiment Construction
[0028] In order to make the above objects, features and advantages of the present invention more comprehensible, specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0029] Such as figure 1 As shown, the belt installation tool 100 of this embodiment includes an eccentric rotation part 1 , a torsion-proof connection part 2 , a rotation operation part 3 and a push-in part 5 .
[0030] The eccentric rotating part 1 has a circumferential belt bearing surface, and an opposite axial first end surface S1 and a second end surface S2. The belt bearing surface is divided into a first belt bearing surface S3 and a second belt bearing surface S4 along the circumferential direction. .
[0031] combine figure 2 and image 3 As shown, the anti-torsion connection part 2 is fixed on the first end surface S1 and is used to realize the anti-torsion connection between the eccentric rotating part 1 and the pulley 6 . ...

The invention discloses a belt mounting tool which comprises an eccentric rotation part, a torsion-resistant connecting part, a rotation operation part and a pushing-in part, wherein the eccentric rotation part is provided with a circumferential belt bearing surface, and an axial first end face and an axial second end face that are oppositely arranged; the belt bearing surface is divided into a first belt bearing surface and a second belt bearing surface in the circumferential direction; the torsion-resistant connecting part is fixedly arranged at the first end face; an axis of the torsion-resistant connecting part acts as a rotation axis of the eccentric rotation part; the rotation radiuses of the first belt bearing surface and the second belt bearing surface are less than orequal to the radius of a rim of a belt pulley respectively; the rotation operation part is fixedly arranged at the second end face, and used to be matched with a rotation mounting tool to impel the eccentric rotation part to rotate; the pushing-in part is fixedly arranged at the second belt bearing surface and extends along the circumferential direction of the eccentric rotation part; the pushing-in part is provided with a belt pushing-in surface; the belt pushing-in face faces one side, on which thetorsion-resistant connecting part is arranged, of theeccentric rotation part;and the belt pushing-in face is gradually kept far from the rotation operation part in the axial direction from the eccentric rotation part to the torsion-resistant connecting part. The belt mounting tool solves the problem that the conventional belt mounting tool is relatively complicated in structure.
Description
technical field [0001] The present invention relates to a belt installation tool. Background technique [0002] A belt drive is a commonly used mechanical power transmission device, which includes multiple (at least two) pulleys and a belt that is sleeved on the pulleys and engaged with the pulley grooves. When assembling a belt drive, use the belt installation tool to gradually snap the belt into the pulley groove. [0003] There are many kinds of belt installation tools in the prior art. For example, the European patent document with the publication number EP0831247B1, the US patent document with the publication number US4193310, and the publication number CN1471614A all disclose a belt installation tool. However, the existing belt installation tools all have the following problems: 1) the structure is relatively complicated; 2) the belt will be turned up during the belt installation process so that the belt will fall out, resulting in low installation efficiency; 2) the ...
