Abstract
The invention discloses a motor reducer protector, solving the problem that devices in the prior art are incapable of protecting motor reducers effectively. The motor reducer protector is characterized in that a motor reducer is mounted on an upper end face of a supporting base; an output end of the motor reducer is connected with a toothed-chain coupler; an upper coupling sleeves a load input shaft, the upper end of the upper coupling is connected with the toothed-chain coupler through a bush roller chain, and the lower end of the upper coupling is integrally fixed to a lower coupling through a safety pin, a nut and a spring washer; and the lower coupling is connected with the load input shaft through keys. The motor reducer protector adopts the toothed-chain coupler and is added with one safety unit; the safety pin is cut off when load exceeds a preset limit, the motor reducer is separated from the load; thus, the motor reducer is protected, damage to the motor reducer is avoided, and the motor reducer can continue to be used only after small parts thereof are changed. The motor reducer protector is safe, convenient, laborsaving and timesaving and further is easy and convenient to maintain when in failure; by the motor reducer protector, maintenance and operating efficiency is improved greatly while production cost is lowered.
Description
Technical field
The present invention relates to a kind of safety protection device, relate to a kind of protective gear of motor reducer or rather.
Background technique
Motor reducer and the motor mixture together with reducer group, is widely used in transmission device, the thickner, agitating vessel, ore pulp preprocessor etc. of such as various washing appliance.The said equipment is in position comparatively crucial in washing system, and working condition is poor, and load is large, needs again to run continuously for a long time simultaneously, and this just requires that the rate of fault of retarder and motor must be lower, improves the protection to it.
Common way is the Thermal protection realizing motor by the current overload in automatically controlled.Operating voltage due to scene is not very stable, and simultaneously select design factor and the real operating mode of motor have a certain distance, results through current overload to realize to the protection of motor reducer that usually things turn out contrary to one's wishes.In using process, because overload uses, often occur the rotten tooth of gear mesh in retarder and shutdown maintenance of having to, change speed reducer, the normal operation of influential system, customer satisfaction is not high.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art and a kind of motor reducer protective gear is provided, effectively can protect motor reducer.
The present invention includes motor reducer, load input shaft, it is characterized in that: also comprise bearing, toothed chain coupling, safety pin, upper shaft coupling, lower shaft coupling, key, motor reducer is arranged on bearing upper-end surface, and the output shaft end of motor reducer connects toothed chain coupling; Upper shaft coupling is enclosed within load input shaft, and upper end is connected with toothed chain coupling by bush roller chain, and lower end and lower shaft coupling are integrally fixed by safety pin and nut, spring washer, and lower shaft coupling is connected with load input shaft by key.
As shown from the above technical solution, the present invention adopts toothed chain coupling, increase a set of safety installations, after traffic overload exceedes predetermined threshold, safety pin is cut off, and motor reducer and load depart from, thus protect motor reducer, avoid the impaired of motor reducer, only need to change widget later and can continue to use; Safe and convenient, time saving and energy saving, emergency maintenance is simple and convenient, and maintenance, efficiency of operation improve greatly, reduce cost of production.
Accompanying drawing explanation
Accompanying drawing is structural representation of the present invention.
In figure, 1, motor reducer, 2, toothed chain coupling, 3, bearing, 4, safety pin, 5, load input shaft, 6, bush roller chain, 7, upper shaft coupling, 8, lower shaft coupling, 9, key.
Embodiment
Below in conjunction with accompanying drawing, the present invention is further illustrated.
As shown in drawings, bearing 3 is flange, steel pipe welding fitting, and side has observation panel, and convenient lubrication, changes spare part; Motor reducer 1 is connected with bearing 3 upper-end surface by bolt; Toothed chain coupling 2 is Cast Steel, is arranged on the output shaft end of motor reducer 1; Upper shaft coupling 7 is Cast Steel, is enclosed within load input shaft 5; Lower shaft coupling 8 is also Cast Steel, is connected with load input shaft 5 by key 9; The upper end of upper shaft coupling 7 is connected with toothed chain coupling 2 by standard piece bush roller chain 6, and lower end and lower shaft coupling 8 are integrally fixed by safety pin 4 and nut, spring washer.
Working principle: be arranged on the motor reducer 1 on bearing 3 be rotated through toothed chain coupling 2, the upper shaft coupling 7 of bush roller chain 6 driving casing on load input shaft 5 rotates, upper and lower shaft coupling 7,8 forms one by safety pin 4, lower shaft coupling 8 passes to load input shaft 5 by key 9 driving force, thus drives the associated components that is connected with load input shaft 5 to rotate to meet normal need of work.When operating mode changes, after load exceedes the specified output torque of motor reducer 1, transmission tie between upper shaft coupling 7 and lower shaft coupling 8 and safety pin 4 are cut off, lower shaft coupling 8 and load input shaft 5 stop the rotation, having there is unloaded operation in motor reducer 1, avoids the phenomenon of motor reducer overload operation.Later only need to change safety pin 4 and can restart work.
