Abstract
A kind of segmentation axle construction of lifting motor is broadly divided into two parts: main shaft and shaft coupling, and whole includes main shaft, shaft coupling, soket head cap screw, spring washer.The non-shaft stretching end of main shaft has a boss, and there are four uniformly distributed threaded holes on the end face between boss and motor outer cover platform.There is a shrinkage pool on one end face of shaft coupling, there are four uniformly distributed through-holes between shrinkage pool and shaft coupling maximum outer circle.There is an excessive platform between shaft coupling erecting bed and connecting table.Connecting table is processed according to the fit dimension of encoder or overspeed switch, guarantees bounce within 0.03mm.The main shaft of motor and shaft coupling are connected and fixed with soket head cap screw and spring washer, and adjust the bounce of connecting table by pre-tightening four screws, guarantees whole final bounce within 0.05mm.Integrally-built axis is split using segmented mode to reduce difficulty of processing and transport difficulty and improve production efficiency, greatly reduce the maintenance guarantee and maintenance and repair difficulty of motor.To improve the product quality of bridge motor on the whole.
Description
Technical field
The utility model relates to the main shaft of encoder or the three-phase asynchronous motor for crane of overspeed switch band shaft coupling
Segmentation axle construction.
Background technique
Nowadays rising in bridge motor industry reuses the occupation rate of market of frequency converting speed regulating three-phase asynchronous electromotor increasingly
The performance advantage of height, motor is also more and more obvious, therefore in order to more accurately be controlled such motor, is usually given and is being risen
The motor of the key positions such as liter is equipped with encoder or overspeed switch.Encoder and the mounting structure of overspeed switch are all similar, substantially
It is divided into axle sleeve type and small spindle-type two major classes, but it is substantially coincident for the structural requirement of motor shaft, and most critical is all wanted
Guarantee that the shaft coupling internal diameter that the connecting table diameter of motor shaft couples with the sleeve diameter or small axis of encoder or overspeed switch guarantees
Cooperation is consistent.And the cooperation internal diameter of encoder and this small device of overspeed switch is generally held atBetween, for
Micro-machine directly can process corresponding connecting table in the non-shaft stretching end of motor shaft, but the axis of large-size machine is come
It says, it is quite big to process tiny connecting table difficulty, it is difficult to ensure that the bounce of connecting table, and transports and maintenance is all extremely difficult.That
Just need a kind of segmentation axle construction for such motor.
Utility model content
This motor sectional axle construction is broadly divided into two parts: main shaft and shaft coupling, it is whole include main shaft, it is shaft coupling, interior
Hex screw, spring washer.
The non-shaft stretching end of main shaft has a boss, and there are four uniformly distributed spiral shells on the end face between boss and motor outer cover platform
Pit.There is a shrinkage pool on one end face of shaft coupling, there are four uniformly distributed through-holes between shrinkage pool and shaft coupling maximum outer circle.Joining
There is an excessive platform between joint erecting bed and connecting table.Connecting table is processed according to the fit dimension of encoder or overspeed switch,
Guarantee bounce within 0.03mm.
The main shaft of motor and shaft coupling are connected and fixed with soket head cap screw and spring washer, and by pre-tightening four spiral shells
It follows closely to adjust the bounce of connecting table, guarantees whole final bounce within 0.05mm.
The beneficial effects of the utility model are:
In lifting frequent motor starting and braking, frequent positive and negative rotation, frequently change the operating condition of revolving speed, frequent changes torque
Under, it often will lead to small axis platform bounce in the integrated axle construction of large-size machine and increase, maintenance and repair is difficult.Integrally-built axis
It is split using segmented mode to not only reduce difficulty of processing and transport difficulty and improve production efficiency, guarantee simultaneously
Small axis can also be readjusted by pre-loading screw during maintenance to guarantee the bounce of small axis connecting table, greatly reduce motor
Maintenance guarantee and maintenance and repair difficulty.To improve the product quality of bridge motor on the whole.

Specific embodiment
1. processing the boss that a height is 6mm in main shaft non-shaft stretching end by Fig. 1, boss diameter tolerance uses h7, convex
Platform bounce guarantees within 0.03mm；4 uniformly distributed M6 threaded holes are processed on end face between boss and motor outer cover platform,
Centrad guaranteesWithin.
2. process the shrinkage pool that one depth is 7mm on shaft coupling by Fig. 3, shrinkage pool diameter tolerance uses H7, in shrinkage pool and
Processed between shaft coupling maximum outer circle 4 it is uniformly distributedThrough-hole, centrad guaranteesWithin.In shaft coupling
Having a length between installation hole platform and connecting table is the excessive platform of 15mm or so.Connecting table is according to encoder or overspeed switch
Fit dimension processing, bounce guarantee within 0.03mm.
3. assembling each components by Fig. 5.The shrinkage pool of shaft coupling (serial number 4) is covered on the boss of main shaft (serial number 1) first
It is locked, it is then with 4 soket head cap screws (serial number 2) and 4 spring washers (serial number 3) that shaft coupling (serial number 4) is uniformly distributed by 4Hole pre-tightens on 4 threaded holes of main shaft (serial number 1), finally with the bounce of pulsation detecting instrument detection connecting table part
And the bounce of connecting table in shaft coupling (serial number 4) is adjusted by pre-tightening 4 soket head cap screws (serial number 2) again, guarantee final
The connecting table jitter values of axis joint portions are segmented within 0.05mm.
4. also can still detect connection again during the maintenance of motor use site when motor is whole after the assembly is completed
The jitter values of platform simultaneously guarantee the bounce of connecting table by adjusting 4 soket head cap screws (serial number 2), ensure that lifting motor
Service performance.
