Assist with assembly tasks.

SUMMARY OF THE INVENTION

The purpose of the present invention is to solve the current assembly problem of the planetary shaft of the wind power gearbox and provide a structure with simple structure, low cost and convenient operation and use, which reduces the labor intensity of the staff and improves the efficiency.

The purpose of the present invention is achieved through the following technical solutions, a tooling structure for assembling a planetary bearing of a wind power gearbox, which mainly includes a main rod, a support seat, a fixed pin, a support leg, a bolt, a gasket, a nut, a beam plate , a tripod, and a fixed pin. The main rod passes through the support seat and the tripod. The main rod is matched with the inner thread of the support seat and the inner thread of the tripod through the external thread. The feet of the support seat pass through the fixed pin. It is fixed with the upper connecting hole of the supporting leg, one end of each beam plate is connected with the connecting hole in the middle part of the supporting leg through a bolt, and the other end is connected with the foot of the tripod through the second fixing pin.

Preferably, the three feet of the support base are respectively fixedly connected to the coupling holes on the upper part of the three support legs through a fixed pin.

Preferably, the two sides of the support legs are each attached to a beam plate, and are fixedly connected by bolts, washers and nuts, and the three support legs share six beam plates.

As a preference: the support leg has a support foot, which is used as a bearing point to hook the inner ring of the bearing during operation and use. The three support feet are the three bearing points. The stability of the three points on one side is used to make the tooling hang the bearing smoothly. disassembly.

As a preference: the main pole has lifting lug holes, which are used when the main pole is rotated or used when operating by borrowing tooling.

Preferably, the lifting lug hole enables the tripod to move on the main rod, and drives the three support legs to move through the beam plate, so that the circumference controlled by the three support legs changes to adapt to the installation of planetary bearings with different inner diameters.

The invention designs suitable tooling according to the difficulty of assembling the planetary bearing of the wind power gearbox, and has the characteristics of simple structure, convenient operation and use, and reduced labor intensity of staff.

Detailed ways

The present invention will be described in detail below in conjunction with the accompanying drawings: As shown in Figures 1-5, a tooling structure for assembling a planetary bearing of a wind turbine gearbox according to the present invention mainly includes a main rod 1, a support seat 2, a fixing pin 1 3. The supporting leg 4, the bolt 5, the washer 6, the nut 7, the beam plate 8, the tripod 9, and the fixing pin 2 and 10 are composed of two parts, characterized in that the main rod 1 passes through the supporting seat 2 and the tripod 9, and the main The rod 1 is matched with the inner thread 2-1 of the support seat 2 and the inner thread 9-1 of the foot frame 9 through the external thread 1-3, and the foot 2-2 of the support seat 2 is connected with the upper part of the support leg 4 through the fixing pin 1-3. The connecting hole 4-1 is fixed, one end of each beam plate 8 is connected with the connecting hole 4-2 in the middle part of the support leg 4 through the bolt 5, and the other end is connected with the foot 9-2 of the tripod 9 through the second fixing pin 10, so The three feet 2-2 of the support base 2 are respectively fixedly connected with the coupling holes 4-1 on the upper part of the three support legs 4 through a fixing pin-3. Bolts 5, washers 6, and nuts 7 are fixedly connected, and the three support legs 4 share six beam plates 8. The support leg 4 has a support foot 4-3, which is used as a bearing point to hook the inner ring of the bearing during operation and use. The three supporting feet are the three bearing points, and the stability of the three points on one side is used to make the tooling hanging bearing be disassembled and assembled smoothly. It is used when borrowing tooling to operate, the lifting lug hole 1-1 can make the tripod 9 move on the main pole 1, and drive the three support legs 4 to move through the beam plate 8, so that the circumference controlled by the three support legs 4 changes to suit Planetary bearings with different inner diameters are installed.

The principle of the invention is as follows: the main rod passes through the support seat and the tripod, and is matched with the inner thread of the support seat and the tripod through the external thread, and the three legs of the support seat are respectively connected by three fixing pins. It is connected with the upper holes of the three supporting legs, one end of each beam plate is connected with the hole in the middle part of the supporting leg through bolts, and the other end of each beam plate is connected with one foot of the tripod through the second fixing pin.
