Description
Technical field
The invention belongs to mechanical fastener technical field, specifically a kind of soft start coupler of motor.
Background technology
Shaft coupling is to be allowed to rotate jointly to transmit for two axis (driving shaft and driven shaft) coupled in different institutions
The machine components of torque, in the power transmission of high-speed overload, some shaft couplings also have buffering, vibration damping and improve shafting dynamic
The effect of energy, shaft coupling are made of two half parts, couple respectively with driving shaft and driven shaft, and general engine is mostly by means of connection
Axis device is connected with working machine.Impact force is higher in high-speed rotation process for shaft coupling, since two half a couplers of shaft coupling are
Rigid contact, it is easy to clashing and breaking phenomenon occur, influence the use of shaft coupling, reduce its service life, it would be highly desirable to improve.
Also occur the technical solution of some shaft couplings, such as one application No. is CN201610245117.5 in the prior art
Item Chinese patent discloses a kind of motor coupler, and the shaft coupling is not affixed by two coupled main shafts, passes through one
Two main shafts are linked together by a snake spring；Shaft coupling mainly by case, coupling sleeve, by the snake spring in embedded cover body come
Torque is transmitted, advantage mainly has：Good damping result, long lifespan, bear larger fluctuating load range, clean boot, it is efficient,
Noise is low, it is reliable for operation, lubricate, simple structure, easy disassembly, allow larger installation deviation, allow rotor have certain deviation,
Cause have good adaptability, high reliability, light weight, appearance and size small, simple when axis offset by ten sufficient flexibilities
Process for making.
The technical solution realizes certain buffering when electric motor starting by the effect of snake spring；But in the program with
The frequent starting of motor, will produce larger torque, and the shaft coupling only buffered by elastic element is susceptible to clashing and breaking.For upper
Situation is stated, the present invention proposes a kind of soft start shaft coupling；It can be realized by the shaft coupling and be passed between motor shaft and driven shaft
Dynamic transition.
