Problems solved by technology

[0002] The gear pump is a commonly used power device. Its working principle is that two gears rotate in two closed spaces in the gear pump, and the pressure of the liquid is increased by the change of the working volume formed between the pump cylinder and the meshing gear. The side plate is the key component to realize the oil in and out of the high-pressure gear pump. Whether the structure of the side plate is reasonable or not directly affects the quality and performance of the entire component. The side plate must be connected with the pump body. The existing side plate and the pump body are Single-plane connection, this connection will cause radial displacement between the side plate and the pump body, thus affecting the sealing performance of the side plate and the pump body

Embodiment Construction

[0009] See figure 1 , figure 2 , a side plate structure, which includes a side plate body 1, gear shaft holes 2-1, 2-2 are arranged on the side plate body 1, and a seal is arranged on the side corresponding to the gear shaft holes 2-1, 2-2 Groove 3, three positioning protrusions 4 are arranged on the side plate body 1, and positioning protrusions 4 are respectively arranged between the outer ends of the gear shaft holes 2-1, 2-2 and the gear shaft holes 2-1, 2-2. When installing, when the positioning protrusion is connected with the pump body, the positioning is realized through the positioning protrusion, which effectively prevents the radial displacement of the side plate and the pump body, and ensures the sealing performance of the side plate and the pump body.

[0010] In this embodiment, the positioning protrusions 3 are respectively arranged on the side between the outer ends of the gear shaft holes 2-1, 2-2 and the gear shaft holes 2-1, 2-2. Of course, the positioning...

Abstract

The invention provides a side plate structure. The side plate structure is simple and capable of effectively preventing the radial displacement of a side plate and a pump body and guaranteeing the sealing performance of the side plate and the pump body. The side plate structure comprises a side plate body, wherein two gear shaft holes are formed in the side plate body, a sealing groove is formed in one side, corresponding to the gear shaft hole, of the side plate body, and the side plate structure is characterized in that at least two positioning bulges are formed in the side plate body.

Description

technical field [0001] The invention relates to the technical field of gear pump components, in particular to a side plate structure. Background technique [0002] The gear pump is a commonly used power device. Its working principle is that two gears rotate in two closed spaces in the gear pump, and the pressure of the liquid is increased by the change of the working volume formed between the pump cylinder and the meshing gear. The side plate is the key component to realize the oil in and out of the high-pressure gear pump. Whether the structure of the side plate is reasonable or not directly affects the quality and performance of the entire component. The side plate must be connected with the pump body. The existing side plate and the pump body are Single-plane connection, this connection will cause radial displacement between the side plate and the pump body, thus affecting the sealing performance of the side plate and the pump body.
