Abstract
The invention provides a side plate structure of a gear pump. The structure is simple, the working pressure balance can be effectively guaranteed, wear resistance and pressure resistance are better, and the service life is long. The structure comprises a side plate, wherein two gear shaft holes are formed in the side plate at an interval, bearing holes coaxial with the corresponding gear shaft holes are formed in the side plate close to end surfaces of gears, the diameter of the bearing holes is larger than that of the gear shaft holes, oil holes are formed in the center of the side plate, a 45-degree chamfering is arranged between one side surface of the side plate and the adjacent end surface, two main unloading grooves communicating with edges of the side plate are formed in the middle of the side plate on two sides of the oil holes, an oil groove communicating the two gear shaft holes is formed in one end of the inner side of the main unloading groove on one side, the main unloading groove on one side and the oil groove form a communicated T-shape, and symmetric arc-shaped auxiliary unloading grooves are formed in the inner side end of the main unloading groove on the other side and the oil groove opposite to the main unloading groove.
Description
Technical field
The present invention relates to technical field of hydraulic elements, be specially gear pump side-plank structure.
Background technologyAlong with gear pump instructions for use constantly improves, side plate is as the core part of gear pump, the performance impact of gear pump is very big, and along with the raising of pressure rating, the radial imbalance force that principal and subordinate's gear shaft of gear pump is subject to is greatly improved, and also relatively larger with the friction of gear face at high temperature, high pressure, high speed lower side panel, thus affecting service life.
Summary of the invention
For the problems referred to above, the invention provides gear pump side-plank structure, its simple in construction, can effectively ensure that operating pressure balances, wearability, resistance to pressure are all relatively good, long service life.
Its technical scheme is such that it and includes side plate, it is characterized in that: described side plate is interval with two gear shaft holes, the dead eye coaxial with each described gear shaft holes is offered on the described side plate of gear face, described dead eye aperture is more than described gear shaft holes aperture, described side plate center is provided with oilhole, the chamfering of 45 ° it is provided with between the end face being adjacent on one side of described side plate, two the main compensating grooves communicated with its edge it are provided with in the middle part of the described side plate of described oilhole both sides, the described main compensating groove medial end of side is communicated with the oil groove of two described gear shaft holes, the described main compensating groove of side forms, with described oil groove, the T-shaped connected, the described main compensating groove medial extremity of opposite side and described oil groove corresponding thereto are provided with the secondary compensating groove of the circular arc of symmetry.
Its number being further characterized by described oilhole has at least two.
The invention has the beneficial effects as follows, the chamfering of 45 ° it is provided with between the end face being adjacent on one side of side plate, under high-pressure work state, then effectively play the effect of balanced radial force, two the main compensating grooves communicated with its edge it are provided with in the middle part of the side plate of oilhole both sides, effectively increase unloading effect, reduce vibrations, reduce noise, the main compensating groove medial end of side is communicated with the oil groove of two gear shaft holes, the main compensating groove of side forms, with oil groove, the T-shaped connected, during work, pressure oil enters two gear shaft holes by oil groove, two gear shaft holes are effectively lubricated, the main compensating groove medial extremity of opposite side and oil groove corresponding thereto are provided with the secondary compensating groove of the circular arc of symmetry simultaneously, it is prevented effectively from unloading process and produces stress concentration, can off-load gently, toleration is enhanced in using, long service life.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Detailed description of the invention
nullAs shown in Figure 1，The present invention includes side plate 1，Side plate 1 is interval with two gear shaft holes 2，The dead eye 3 coaxial with each gear shaft holes 2 is offered on the side plate 1 of gear face，Dead eye 3 aperture is more than gear shaft holes 2 aperture，Side plate 1 center is provided with oilhole 4，The number of oilhole 4 has at least two，Increase propulsive thrust，And raising lubricant effect，The chamfering 5 of 45 ° it is provided with between the end face being adjacent on one side of side plate 1，Under high-pressure work state, then effectively play the effect of balanced radial force，Two communicated main compensating grooves 6 it are provided with its edge in the middle part of the side plate 1 of oilhole 4 both sides，Effectively increase unloading effect，Reduce vibrations，Reduce noise，Main compensating groove 6 medial end of side is communicated with the oil groove 7 of two gear shaft holes 2，The main compensating groove 6 of side forms, with oil groove 7, the T-shaped connected，During work, pressure oil enters two gear shaft holes 2 by oil groove 7，Two gear shaft holes 2 are effectively lubricated，Main compensating groove 6 medial extremity of opposite side and oil groove 7 corresponding thereto are provided with the secondary compensating groove 8 of the circular arc of symmetry，It is prevented effectively from unloading process and produces stress concentration，Can off-load gently，Toleration is enhanced in using，Long service life.
