Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts all belong to the protection scope of the present invention.

Referring to fig. 1-5, the present invention provides a technical solution:

as shown in fig. 1, the whole structure of the special device for dismounting the speed reducer is composed of three parts, namely, a fixing bolt 403 and a fixing nut 404 for fixing the shaft sleeve 2, a fastening screw rod for abutting against the main shaft 1, an abutting block 406 and a turning head 407, and a main arm 6 for vibrating the shaft sleeve 2 and a secondary arm 8 gripped by the shaft sleeve 2, and during specific operation, a 35cm 10cm stainless steel plate is used as a fixing block 401, an M16 bolt is used as the fixing bolt 403, and a fastening screw shaft 405 is used as an abutting shaft, so that the main shaft 1 and the shaft sleeve 2 of the speed reducer are separated;

the clamping mechanism 4 starts to work, the shaft sleeve 2 is uniformly provided with the lock holes 3, the fixing bolts 403 are firstly installed in the lock holes 3, as the whole fixing bolt 403 is installed in the fixing groove 402 on the fixing block 401, the whole fixing bolt 403 can freely rotate, when two fixing bolts 403 are simultaneously rotated into the lock holes 3, the fixing nuts 404 on the fixing bolts 403 are screwed to prevent the fixing bolts 403 from unthreading, when the fixing bolts 403 are installed, the fastening screw rod on the fixing block 401 is firstly rotated forward to enable the abutting block 406 on the fastening screw rod to be abutted against the hollow main shaft 1 in the shaft sleeve 2, then the main arm 6 and the secondary arm 8 on the fixing block 401 are folded, the stop block 7 on the main arm 6 is fixed on the shaft sleeve 2, the fastening screw rod is continuously rotated forward while the vibration motor 9 on the main arm 6 is started, when the shaft sleeve 2 starts to fall off from the main shaft 1, at this time, as shown in fig. 4, the vibration motor 9 on the main shaft 1 is turned off, the secondary arm 8 on the main arm 6 is unfolded, one end of the secondary arm 8 is clamped with the shaft sleeve 2 which is partially separated, and the rotary head 407 on the fastening screw rod is continuously rotated, so that the whole shaft sleeve 2 falls off from the main shaft 1;

because the speed reducer adopts a single-key hollow shaft, the matching length reaches 300MM, the flat key length is more than 200MM, the resistance is large in the dismounting process, and the dismounting is difficult; the clearance between the speed reducer and the travelling wheel is small in the dismounting process, the travelling wheel shaft can only be jacked on the outer side by adopting a jack, the inner side of the speed reducer can not be jacked due to the fact that the outer diameter of the hollow shaft of the speed reducer is smaller than the inner diameter of the travelling wheel shaft sleeve 2, the hollow shaft cannot be jacked by a press machine, the hollow shaft is not stressed, the speed reducer cannot be dismounted, if the speed reducer shell is jacked directly, the speed reducer shell is broken easily due to the fact that the stress of a casting is not uniform, the dismounting device of the utility model utilizes the central shaft of the speed reducer and the flange connecting position of the speed reducer, the fixing bolts 403 are symmetrically and additionally arranged, so that the middle fastening screw rod does work and the top shaft moves, the speed reducer shaft sleeve 2 and the whole can be stressed uniformly, the damage caused by the nonuniform stress of the speed reducer is avoided, the labor intensity and the difficulty are increased for overhauling and replacement, and the overhauling cost is increased;

if the space of the whole speed reducer is small, the operation difficulty of a large-scale device or equipment is high, the fixing bolt 403 can be directly installed in the lock hole 3, the main arm 6 and the secondary arm 8 which are located on the lock block 5 are folded, the separation work of the whole shaft sleeve 2 is not participated, the occupied area of the special device for disassembling the whole speed reducer is reduced, and the operation of workers is more convenient and rapid.

The utility model discloses a working process:

firstly installing a fixing bolt 403 in a lock hole 3, then screwing a fixing nut 404 on the fixing bolt 403, after the fixing bolt 403 is installed, forward rotating a fastening screw rod on a fixing block 401 to enable a butting block 406 on the fastening screw rod to be butted with a hollow main shaft 1 in a shaft sleeve 2, then folding a main arm 6 and a secondary arm 8 on the fixing block 401, fixing a stop dog 7 on the main arm 6 on the shaft sleeve 2, starting a vibration motor 9 on the main arm 6 and forward continuing to rotate the fastening screw rod, after the shaft sleeve 2 starts to fall off from the main shaft 1, closing the vibration motor 9 on the main shaft 1, unfolding the secondary arm 8 on the main arm 6, clamping one end of the secondary arm 8 with the shaft sleeve 2 which is partially separated, and continuing to rotate a rotary head 407 on the fastening screw rod to enable the whole shaft sleeve 2 to fall off from the main shaft 1.

Additionally, it is serious to run into rust on the main shaft 1, leads to whole main shaft 1 to die with the card of axle sleeve 2, can't utilize heating device winding on axle sleeve 2 when adding lubricating oil this moment, heats axle sleeve 2, carries out above-mentioned operation after the heating again.
