Description

Technical Field

[0001] The utility model relates to the field of oil distribution plates, in particular to a spherical oil distribution plate. Background Art

[0002] The spherical oil distribution plate is a key component in a hydraulic motor or pump, mainly playing the role of high and low oil circuit distribution. It enables the motor or pump to output torque under the action of high-pressure oil, and at the same time discharges the high-pressure oil in the plunger cavity that stops outputting torque when under low-pressure oil.

[0003] In the existing spherical oil distribution plate, during use, there is usually a lack of buffering between it and the pump body, which easily leads to a certain collision and friction between the oil distribution plate and the pump body due to the impact force generated when the oil passes through the oil distribution plate, making it easy to generate noise when the oil distribution plate distributes oil.

[0004] Therefore, aiming at the problem that there is a lack of buffering between the above-mentioned oil distribution plate and the pump body, which easily leads to a certain collision and friction between the oil distribution plate and the pump body due to the impact force generated when the oil passes through the oil distribution plate, making it easy to generate noise when the oil distribution plate distributes oil, a spherical oil distribution plate can be designed. By fitting and fixing the primary rubber noise reduction sleeve and the secondary rubber noise reduction sleeve at the outer ends of the oil outlet and the oil outlet hole, the spherical oil distribution plate can form a buffer with the oil supply component of the pump body, facilitating the solution of the above problems. Summary of the Utility Model

[0005] In order to overcome the problem that in the existing spherical oil distribution plate, during use, there is usually a lack of buffering between it and the pump body, which easily leads to a certain collision and friction between the oil distribution plate and the pump body due to the impact force generated when the oil passes through the oil distribution plate, making it easy to generate noise when the oil distribution plate distributes oil.

By combining the nine groups of damping grooves 15, when the oil flows through the oil distribution disc under high pressure, the pressure and flow rate of the oil will change sharply, which may lead to pressure pulsation and flow rate pulsation in the hydraulic system, and then cause vibration and noise. The existence of the damping grooves 15 can slow down this change in pressure and flow rate, playing a role in buffering and vibration reduction. At the same time, the design of the damping grooves 15 can also improve the lubrication conditions between the oil distribution disc and adjacent components.

By combining the multiple groups of meshing teeth 23, it becomes the positioning reference of the spherical oil distribution disk in the hydraulic system. Through precise cooperation with other components, the internal teeth can ensure the correct position and installation direction of the oil distribution disk in the system.

[0028] When working, when the oil liquid flows through the oil distribution disk under high pressure, the pressure and flow rate of the oil liquid will change sharply, which may cause pressure pulsation and flow rate pulsation in the hydraulic system, and then cause vibration and noise. The existence of the damping groove 15 can slow down this change in pressure and flow rate, playing a role in buffering and vibration reduction. At the same time, the design of the damping groove 15 can also improve the lubrication conditions between the oil distribution disk and adjacent components. The damping groove 15 helps to form a more stable oil film, reduce friction and wear, and extend the service life of the oil distribution disk.

[0029] At the same time, the staff can install the oil port fitting sleeve 19 and the oil hole fitting sleeve 17 along the inner walls of the first-stage noise reduction groove 10 and the second-stage noise reduction groove 12, so that the first-stage rubber noise reduction sleeve 16 and the second-stage rubber noise reduction sleeve 18 can be fixed at the outer ends of the oil outlet holes 9 and the oil outlet holes 9.

[0030] Through the above steps, when the oil flows through the oil distribution disc under high pressure, the pressure and flow rate of the oil will change sharply. The presence of the damping groove 15 can slow down this change in pressure and flow rate, playing a role in buffering and vibration reduction. At the same time, the primary rubber noise reduction sleeve 16 and the secondary rubber noise reduction sleeve 18 can be fixed at the outer ends of the oil outlet holes 9 and the oil outlet holes 9.
