Embodiment Construction

[0014] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0015] figure 1 with figure 2 One embodiment of the invention is shown. The manually adjustable variable gear pump of the present invention consists of a pump body 7, two externally meshed driving gears 1 and a driven gear 6, a reset block 3, an adjustment block 11, a toothed slider 9, a return spring 4, The adjustment handle 10, the ring gear 12 and the like are composed. Both the driving gear 1 and the driven gear 6 are spur gears, wherein the driving gear 1 is installed on the driving shaft 2, the position of the driving shaft 2 is fixed and cannot move axially, and both sides of the driving gear 1 are sealed by the pump body 7. The driven gear 6 is installed on the driven shaft 5, which is provided with a keyway, and the driven gear 6 can move axially along the keyway.

Abstract

The invention provides a manual-adjusted variable gear pump. The manual-adjusted variable gear pump comprises a pump body (7), a driving gear (1), a driven gear (6), an adjusting stopper (11), a gear ring (12), a return stopper (3), a return spring (4), a driving shaft (2), a driven shaft (5), an adjusting handle (10), a tooth-shaped slide block (9) and a baffle plate (8); the driving shaft (2) cannot axially move; and the driven gear (6), the adjusting stopper (11) and the return stopper (3) are all mounted on the driven shaft (5), and can move along the driven shaft (5). The adjusting handle (10) is shaken to enable the adjusting stopper (11) to push the driven gear (6), the return stopper (3) and the tooth-shaped slide block (9) to axially move, so that the engagement width of the driving gear (1) and the driven gear (6) can be changed, and the manual displacement adjustment of the gear pump is realized. A displacement adjusting device is simple in structure and convenient to operate, and can change the displacement of the gear pump in real time according to working conditions.

Description

technical field [0001] The invention relates to the technical field of gear pumps, in particular to a gear pump that can be manually adjusted to change displacement. Background technique [0002] Gear pumps are commonly used hydraulic components in hydraulic transmission systems, and can be divided into two types: external gear pumps and internal gear pumps. The advantages of gear pumps are simple structure, small size, light weight, low price, reliable operation, strong self-priming ability, and insensitivity to oil pollution. No substantive solution has been found, which limits the wide application of gear pumps. Most of the existing variable gear pump schemes have complex structures, and the maintenance and replacement of gear pump parts are difficult, which hinders the development of variable gear pumps to a certain extent. Contents of the invention [0003] The object of the present invention is to provide a variable displacement gear pump with simple and quick oper...
