[0030] Such as figure 2 and 3 As shown, according to the first embodiment of the present invention, the toothed belt pretensioning device includes a toothed plate seat 10, a toothed plate 20, a friction reducing part, a position adjusting member 40 and the like. The tooth plate seat 10 is used to carry other components, and at least one first mounting groove 11 for carrying the friction reducing part is provided on the tooth plate seat 10. In order to ensure that the friction reducing part can be easily mounted and dismounted, the first mounting groove 11 runs through the At least one side wall of the board seat 10 is used to form a disassembly opening. The toothed plate 20 is arranged on the toothed plate seat 10 for fixing the toothed belt 60 . The friction reducing part is detachably arranged in the first installation groove 11, and has a working position in contact with the bottom surface of the toothed plate 20, and is used to support the toothed plate 20 to reduce the...

Embodiment 2

[0045] In this embodiment, except that the setting position and working method of the position adjusting member 40 are different from those in the first embodiment, the structures and working methods of other components are the same as those in the first embodiment.

[0046] Such as Figure 4 As shown, specifically, in this embodiment, the tooth plate seat 10 is provided with a second threaded hole 12 penetrating through the tooth plate seat 10 along the thickness direction of the tooth plate seat 10, and the second threaded hole 12 is connected with the first installation groove 11 connectivity. The position adjusting member 40 has a threaded rod section, which is screwed into the second threaded hole 12 and pushes up the friction reducing part, so that the friction reducing part contacts with the toothed plate 20 . In this embodiment, the position adjusting member 40 may be a common bolt or any other structure with a screw section. The anti-friction part can be a rolling a...

Embodiment 3

[0053] In this embodiment, except that the setting position and working method of the position adjusting member 40 are different from those in the first embodiment, the structures and working methods of other components are the same as those in the first embodiment.

[0054] Such as Figure 5 and 6 As shown, in this embodiment, the position adjusting member 40 has a cam segment 41 . Specific as Figure 6 As shown, the position adjustment member 40 is provided with a sleeve with an elliptical cross-sectional shape outside the screw or bolt, and the sleeve forms a cam segment 41 . It should be noted that, the cross-sectional shape of the cam segment 41 may be other shapes, as long as a height difference is generated during the rotation of the position adjusting member 40 .

[0055] In order to cooperate with this kind of position adjustment member 40, a second installation groove 13 is also provided on the gear plate seat 10, the second installation groove 13 is located below...

Abstract

The invention provides a toothed belt pre-tightening device and method. The toothed belt pre-tightening device comprises a toothed plate base, a toothed plate, a friction reduction part and position adjusting pieces, wherein the toothed plate base is provided with at least one first installation groove, the toothed plate is arranged on the toothed plate base, the friction reduction part is arranged in the first installation groove and has a working position where the friction reduction part makes contact with the bottom face of the toothed plate, and the position adjusting pieces are arranged on the toothed plate or the toothed plate base and control the bottom face of the toothed plate to make contact with or be separated from the friction reduction part. The toothed belt pre-tightening device can adjust the friction force between the toothed plate and the toothed plate base according to requirements and is better in pre-tightening effect.

Description

technical field [0001] The invention relates to the application field of belt transmission, in particular to a toothed belt pretensioning device and a toothed belt pretensioning method. Background technique [0002] In the process of using belt drive, the pretension of the drive belt is very important. Specifically in wind power generation equipment, open toothed belts or other toothed belts are usually used for transmission on the pitch bearings of wind turbines. In order to ensure transmission accuracy and transmission efficiency, it is necessary to use a toothed belt preloading device to The belt is pre-tensioned. [0003] Existing toothed belt pretensioning devices such as figure 1 As shown, the toothed belt pretensioning device includes a toothed plate 2, a toothed plate seat 3, a tightening nut 5, a tensioning bolt 4, and the like. The working process of the toothed belt pretensioning device is: the toothed belt 1 is fixed by the toothed plate 2, the toothed plate 2...
