Description

Technical Field

[0001] The utility model relates to the technical field of gear pumps, in particular to a hydraulic cone gear pump. Background Art

[0002] A gear pump is a rotary pump that relies on the change and movement of the working volume created between the pump cylinder and meshing gears to transport liquids or increase pressure. Two gears, a pump body, and front and rear covers form two enclosed chambers. As the gears rotate, the volume of the chamber on the disengaged side increases from smaller to larger, creating a vacuum that draws liquid in. The volume of the chamber on the meshing side decreases from larger to smaller, squeezing the liquid into the pipeline. The suction and discharge chambers are separated by the meshing line of the two gears. The pressure at the discharge port of a gear pump is entirely dependent on the resistance at the pump outlet.

[0003] In the prior art, when gear pumps are used in the hydraulic systems of machine tools or other machinery, they can be used as a hydraulic energy source to provide a certain flow rate and pressure. However, existing hydraulic cylindrical gear pumps are usually fixed by bolts and lack a shock-absorbing mechanism to reduce vibration and buffer the pumps, which shortens the service life of the hydraulic cylindrical gear pumps. To address this problem, we propose a hydraulic cylindrical gear pump to solve the above problem. Utility Model Content

[0004] The purpose of the utility model is to provide a hydraulic component circular cone gear pump to solve the problems raised in the above background technology.

[0009] Preferably, the elastic buffer pad is fixedly mounted on the inner bottom wall of the fixing seat, and one end of the mounting block away from the pump body is fixedly connected to the elastic buffer pad.

[0011] Preferably, four mounting bolts are evenly arranged, and the bottom ends of the four mounting bolts are inserted into adjacent thread grooves and threadedly connected to the inner walls of the thread grooves.

[0012] Preferably, the limit blocks are evenly arranged in a number and are all T-shaped, one end of each limit block is fixedly mounted on the mounting block, and the other end of each limit block passes through the second anti-slip ring and is slidably mounted in the adjacent limit groove.

[0013] Preferably, the second anti-slip ring is fixedly sleeved on the outer wall of the mounting block, and the outer wall of the second anti-slip ring is tightly fitted with the inner wall of the fixing seat.

[0014] Preferably, each of the limit blocks is provided with a guide hole on the surface close to the adjacent guide column, the outer wall of each guide column is slidably connected to the inner wall of the adjacent guide hole, and both ends of each guide column are fixedly mounted on the inner wall of the adjacent limit slot.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] The utility model inserts the cone main body into the installation groove, and the pump body can be fixed by installing bolts. The anti-skid effect of the first anti-skid ring and the second anti-skid ring makes it less likely for relative shaking to occur between the pump body, the installation block and the fixed seat, thereby improving the overall stability. The elastic buffer pad can be used to shock-absorb and buffer the installation block. The guide column guides the limit block. When the limit block slides in the limit groove, the limit block can be reset under the elastic action of the buffer spring, thereby realizing the function of shock-absorbent and buffering the pump body, solving the problem that the existing hydraulic cone gear pump lacks a shock-absorbing mechanism to perform shock-absorption and buffering, so as not to affect the service life of the hydraulic cone gear pump.
