Abstract
The invention discloses a disassembling method of the nylon ferrule of the coupler of a medium-sized motor. The method comprises the steps of, firstly, symmetrically drilling two holes in the circumferential surface of the nylon ferrule of the coupler; secondly, heating the whole coupler in an oasthouse at a heating temperature of 70-90 DEG C for 25-35 minutes; thirdly, taking the coupler out of the oasthouse for cooling; fourthly, after the coupler is cooled, fixing connecting pieces into the two holes of the nylon ferrule; lastly, pulling the two connecting pieces outwards simultaneously, and driving the nylon ferrule to be released from the end of the coupler through the connecting pieces. The disassembling method of the nylon ferrule of the coupler of the medium-sized motor has the advantages of avoiding damage to the nylon ferrule, guaranteeing normal usage of the coupler and normally coupling the coupler onto the motor.
Description
Technical field
The invention belongs to mechanical transmission component technical field, relate to a kind of shaft coupling, relate in particular to a kind of middle size motor shaft coupling nylon ferrule method for dismounting.
Background technology
The shaft coupling that at present a lot of middle size motors adopt is all with nylon ferrule mostly, and lasso adopts interference fit to be connected with shaft coupling, cannot dismantle by usual method.After entering 200 ℃ of high temperature of drying room chance, nylon ferrule melts, and causes shaft coupling normally to use.
If but do not enter drying room heating shaft coupling to 200 ℃, shaft coupling normal spreading again, causes being normally set with shaft coupling.
Summary of the invention
For this reason, technical problem to be solved by this invention is to provide a kind of middle size motor shaft coupling nylon ferrule method for dismounting, and this method for dismounting can not cause the damage of nylon ferrule, has guaranteed that shaft coupling can normally use and normally on motor, be set with shaft coupling.
For solving the problems of the technologies described above, the present invention adopts following technical scheme:
A kind of middle size motor shaft coupling nylon ferrule method for dismounting, it comprises following steps:
Two holes of symmetrical brill on the periphery of the first nylon ferrule at shaft coupling;
Then whole shaft coupling is placed into drying room and heats, heating-up temperature 70-90 ℃, heat time 25-35 minute;
Again shaft coupling is taken out from drying room, cooling;
After shaft coupling is cooling, in two holes of nylon ferrule, fix upper connector;
Finally, pull laterally two connectors, drive nylon ferrule to come off from the termination of shaft coupling by connector simultaneously.
Described hole is screwed hole, and described connector is bolt.
In a preferred embodiment, described heating-up temperature is 80 ℃, and the heat time is 30 minutes.
In the present invention, adopt first low-temperature heat, the rear type of cooling, utilize effect that steel expand with heat and contract with cold than the obvious feature of nylon material, thereby reduce to a certain extent the magnitude of interference between nylon ferrule and shaft coupling, and then by the bolt of screwing on, nylon ferrule is dragged and taken off from shaft coupling again, the heating-up temperature of 70-80 ℃ can not cause the damage of nylon ferrule.
This method for dismounting of the present invention has farthest been protected the integrality of nylon jacket; guaranteed the serviceability of shaft coupling simultaneously; meet client's requirement, also improved the suit mode of this type of shaft coupling simultaneously, made the large batch of suit of this type of shaft coupling become possibility.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail:
Fig. 1 is the structural representation of shaft coupling.
In figure:
100-shaft coupling, 200-nylon ferrule, 201-screwed hole, 202-steel hex bolts.
The specific embodiment
As shown in Figure 1, on the termination of middle size motor shaft coupling 100, interference fit is provided with nylon ferrule 200.Nylon ferrule 200 method for dismounting of this shaft coupling are as follows:
1, the symmetrical screwed hole 201 that bores two M8 on the periphery of the first nylon ferrule 200 at shaft coupling 100;
2, then whole shaft coupling 100 is placed into drying room and heats, heating-up temperature is 80 ℃, 30 minutes heat times;
3, again shaft coupling 100 is taken out from drying room, cooling; Utilize effect that steel expand with heat and contract with cold than the obvious feature of nylon material, thereby reduced to a certain extent the magnitude of interference between nylon ferrule and shaft coupling.
4,, after shaft coupling 100 is cooling, in two screwed holes of nylon ferrule 200, fix M8 steel hex bolts 202;
5, last, pull laterally two steel hex bolts 202 simultaneously, drive nylon ferrule 200 to come off from the termination of shaft coupling 100 by steel hex bolts 202.
Can find out by above-mentioned detailed introduction, this method for dismounting of the present invention has advantages of can not cause nylon ferrule damage, has guaranteed that shaft coupling can normally use and normally on motor, be set with shaft coupling.
But, those of ordinary skill in the art will be appreciated that, above embodiment is only for the present invention is described, and be not used as limitation of the invention, as long as within the scope of connotation of the present invention, variation, modification to the above embodiment all will drop within the scope of claims of the present invention.
