The sleeve comprises at least one sleeve ring, wherein a main body of a radial cross section of the sleeve ring is an open ring; an avoidance position corresponding to a fastening device of the coupling is arranged on the tube wall of the sleeve ring; the outer diameter of the sleeve corresponds to the inner diameter of the coupling; and the inner diameter of the sleeve corresponds to the outer diameter of the shafts. According to the invention, through the arranged sleeve, the problem that the outer diameter of the two connected shafts change can be solved under the precondition that the coupling is not changed, the cost is reduced, the mounting speed is increased, and the mounting is facilitated; the proper sleeve is selected aimed at the situation that the shaft diameter of the shafts connected with the coupling is decreased, and the total thickness of the sleeve ring or a sleeve ring group changes, equal to the radius of the connected shafts; and the sleeve ring or the sleeve ring group is mounted in the inner hole of the coupling, the sleeve ring or the sleeve ring group is rotated to enable the avoidance position on the tube wall of the sleeve ring or the sleeve ring group to correspond to the fastening device of the coupling, then, a new coupling is mounted, and after fastening, the new coupling can be utilized.
Description
Technical field
The present invention relates to plant equipment accessory technical field, particularly relate to one and improve axle and be connected effect with shaft coupling
The sleeve of fruit.
Background technology
The aperture of existing shaft coupling is immutable, when outside two axles (driving shaft and driven shaft) coupled
When footpath changes, need to change the shaft coupling in corresponding aperture, relatively costly and be difficult to change, original
Axial organ also cannot be continuing with, and causes waste.
General engine is mostly connected with working machine by means of shaft coupling.Shaft coupling is used to couple different machine
Two axles (driving shaft and driven shaft) in structure are allowed to jointly rotate to transmit the machine components of moment of torsion.At height
In the power transmission of speed heavy duty, some shaft coupling also has buffering, vibration damping and the effect of raising axle system dynamic property.
Shaft coupling is made up of two halves part, couples with driving shaft and driven shaft respectively, can be described as driving shaft adapter,
Driven shaft adapter.Driving shaft adapter, the aperture of driven shaft adapter are fixed value, couple different size
Driving shaft and driven shaft time need the shaft coupling of different size.
In prior art, coupling spindle to be realized advises declinable connection can only integral replacing shaft coupling or single
Changing driving shaft adapter or driven shaft adapter, cost is high, if the unconventional numeral of the specification of connecting shaft,
It is customized processing, more improves cost.
