Problems solved by technology

[0002] The hydraulic system in industrial equipment often coexists with various pressure conditions. In the booster circuit, two methods are commonly used. One is to use double (multiple) pumps, low pressure and high flow, and switch to small flow when high pressure is required. Not only the structure is complicated , high cost, and the maximum pressure of the hydraulic pump is low, which limits the design and application of the hydraulic system
The other is to use a hydraulic booster, which is an integration of various hydraulic components, with many parts, complex structure, large flow pulsation, and expensive

Abstract

An internal meshing cycloidal gear type hydraulic transformer comprises a casing (1), an eccentric sleeve (2) internally arranged on the casing (1), an internal meshing cycloidal rotor pair (3) sleeved with the eccentric sleeve (2) as well as an upper end cover (4) and a lower end cover (5) which are connected on two sides of the casing (1) through bolts (6) respectively. The hydraulic transformerhas the beneficial effects as follows: the hydraulic transformer has the remarkable advantages of small size, low weight, simple structure, easiness in manufacturing, high compression frequency, small flow pulsation, stable running and multiple functions, and for the cycloidal gear type hydraulic transformer with the position of a flow distributing barrier between an unloading oil opening and a pressurizing oil opening fixed, different pressurization or depressurization ratios can be realized through exchange of the unloading oil opening and the pressurizing oil opening.

Description

technical field [0001] The invention relates to an internal meshing cycloid gear type hydraulic converter, which can increase or decrease the pressure of the input pressure oil in a hydraulic circuit, and has the function of maintaining pressure, which belongs to the mechanical manufacturing hydraulic converter technology. technical background [0002] The hydraulic system in industrial equipment often coexists with various pressure conditions. In the booster circuit, two methods are commonly used. One is to use double (multiple) pumps, low pressure and high flow, and switch to small flow when high pressure is required. Not only the structure is complicated , high cost, and the maximum pressure of the hydraulic pump is low, which limits the design and application of the hydraulic system. The other is to use a hydraulic booster, which is an integration of various hydraulic components, with many parts, complex structure, large flow pulsation, and expensive. Therefore, the dev...
