Technical Field
[0001] The utility model relates to the field of jaw crushers, in particular to a split flywheel of a jaw crusher. Background Art
[0002] For some old mines that need to install large jaw crushers underground, after years of mining and renovation, the original tunnels have become narrower due to the addition of supports, etc., and some large spare parts such as jaw crushers cannot be transported underground. Utility Model Content
[0003] In order to solve the technical problems existing in the prior art, the utility model provides a split flywheel for a jaw crusher, which reduces the transportation size by adopting a split structure.
[0004] To achieve the above purpose, the technical solution of the utility model is as follows:
[0005] A split flywheel for a jaw crusher comprises an annular structure and a middle piece. The annular structure is formed by enclosing a sector piece and an arc piece. The middle piece is detachably mounted at the center of the annular structure.
[0006] As a preferred technical solution, the annular structural member is provided with a plurality of weight-reducing holes evenly distributed in the circumferential direction.
[0007] As a preferred technical solution, the division of the sector-shaped parts and the arc-shaped parts avoids the weight-reducing holes.
[0008] As a preferred technical solution, reinforcing plates are provided between the weight-reducing holes on the sector-shaped member and at the connection between the sector-shaped member and the arc-shaped member.
[0009] As a preferred technical solution, the middle piece is in the shape of a gyro, and a through hole is provided at the center of the middle piece.
[0010] As a preferred technical solution, a flange is provided on the middle piece, and a circular groove is provided on the annular structural piece near the middle circular hole, and the shapes and sizes of the flange and the groove match.
[0011] As a preferred technical solution, corresponding screw holes are provided on the flange and the groove, and the flange of the intermediate component is fixedly connected to the groove of the annular structural component by bolts.
[0012] As a preferred technical solution, the split flywheel is connected to other structures on the jaw crusher through a key.
[0013] Compared with the prior art, the beneficial effects of the utility model are:
[0014] The split flywheel of the jaw crusher of the utility model adopts a split structure, which can reduce the transportation size and is particularly suitable for jaw crushers and other equipment working underground. A plurality of weight-reducing holes are also designed on the split flywheel, which can adjust the counterweight position while reducing the mass. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The technical solution of the utility model is further described below in conjunction with specific implementation methods:
[0022] like Figure 2 As shown, a split flywheel of a jaw crusher includes an annular structure and a middle piece 1. The annular structure is enclosed by a sector piece 2 and an arc piece 3. The middle piece 1 is detachably mounted at the center of the annular structure. The split structure can reduce the transportation size. In this embodiment, the overall structure diameter of the flywheel is 2600 mm, and the maximum size after splitting is 1702 mm.
[0023] The annular structure is provided with a plurality of weight-reducing holes evenly distributed in the circumferential direction. Specifically, the weight-reducing holes are arc-shaped and penetrate the annular structure. The setting of the weight-reducing holes can not only reduce the weight of the split flywheel, but also adjust the position of the counterweight.
[0024] The division of the sector-shaped member 2 and the arc-shaped member 3 avoids the weight-reducing hole to increase the structural strength.
[0025] like Figure 1 and Figure 4As shown, reinforcing plates 21 are provided between the weight-reducing holes on the sector 2 and at the connection between the sector 2 and the arc 3. Specifically, half a reinforcing plate 21 is provided at each end of the sector 2 and the arc 3. The overall shape of the reinforcing plate 21 is similar to a trapezoid and is arranged at the inner circle of the outer edge of the annular structural member. The reinforcing plate 21 on the sector 2 is an integral structure with the sector 2, and the half reinforcing plates 21 at both ends of the arc 3 are also an integral structure with the arc 3.
[0026] like Figure 3 As shown, the middle piece 1 is in the shape of a gyro, a through hole is provided at the center of the middle piece 1 , and a flange 11 is provided at the outer edge of the middle piece 1 .
[0027] like Figure 4 and Figure 5 As shown, a circular groove is provided near the middle circular hole on the annular structure, and the shape and size of the flange 11 and the groove match. The flange 11 and the groove are provided with corresponding screw holes, and the flange 11 of the middle piece 1 is fixedly connected to the groove of the annular structure by bolts 12.
[0028] The split flywheel is connected to other structures on the jaw crusher through a key, and the key is installed at the through hole of the middle piece 1.
[0029] This embodiment is only a further explanation of the present invention, not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to this embodiment as needed, but as long as it is within the scope of the claims of the present invention, it will be protected by the patent law.
