Description
Technical Field
The utility model belongs to the technical field of the shaft coupling, concretely relates to special shaft coupling of hydraulic power unit.
Background
The coupling is a device for connecting two shafts or a shaft and a rotating part, rotating together in the process of transmitting motion and power and not separating under normal conditions. Sometimes it is used as a safety device to prevent the coupled machine parts from bearing excessive load, and it plays the role of overload protection.
The traditional coupler mostly adopts rigid connection, and when the use pressure is high and the motor is frequently started, the oil pump shaft and the coupler are easily damaged, so that the special coupler for the hydraulic power unit is needed to solve the problems.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a special shaft coupling of hydraulic power unit to solve the problem that proposes among the above-mentioned background art.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a special shaft coupling of hydraulic power unit, includes motor output shaft, the junk ring mounting groove has been seted up to motor output shaft's right side tip, the inside of junk ring mounting groove is provided with the junk ring, motor output shaft's right side tip fixedly connected with oil pump input shaft.
The arrangement is used for greatly improving the stability when the output shaft of the motor drives the input shaft of the oil pump to rotate by arranging the lining ring mounting groove matched with the lining ring at the end part of the output shaft of the motor.
Preferably, the thickness of the lining ring is smaller than the depth of the lining ring mounting groove, and the lining ring mounting groove and the lining ring are petal-shaped.
This setting is used for reducing the damage when motor output shaft drives the oil pump input shaft and rotates.
Preferably, the lining ring is a base body made of TPE, the motor output shaft and the oil pump input shaft are both base bodies made of high-strength aluminum alloy, and the high-strength aluminum alloy is aluminum-manganese alloy.
The device is used for carrying out optimization design on the structure, greatly reduces the failure rate and improves the service life and the reliability of the product.
The utility model discloses a technological effect and advantage: this special shaft coupling of hydraulic power unit, set up the junk ring mounting groove that the cooperation junk ring was used through the tip with motor output shaft, the shape of this junk ring is petal shape, damage when motor output shaft drives the oil pump input shaft and rotates can be reduced, stability when motor output shaft drives the oil pump input shaft and rotates has also been improved greatly, the cooperation is motor output shaft and the oil pump input shaft that high strength aluminum alloy made and uses, make structural optimal design that has carried out, greatly reduced the fault rate, product life and reliability have been improved.
