Inner curvilinear low-speed large-torque water hydraulic motor with replaceable wearproof dish

Abstract

The invention discloses an inner curvilinear low-speed large-torque water hydraulic motor with a replaceable wearproof dish. The water hydraulic motor is applicable to a static pressure bearing interval and a structure based on water hydraulic transmission, so that the volume efficiency of the water hydraulic motor can be better met. N combined springs are arranged in a rear cover, a matched fluid is arranged on a center hole of the rear cover, and the matched fluid is pressed on the combined springs; the replaceable wearproof dish is arranged on the end surface of the matched fluid, the replaceable wearproof dish and the matched fluid are fixed, and a rotor is pressed on the end surface of the replaceable wearproof dish; k plungers are respectively arranged in corresponding radial plunger holes of the rotor, the plungers are internally filled with rolling bodies, and a stator sleeves the rotor; the inner walls of the plungers and the rolling bodies form friction pairs, the front end cover is supported on the rotor by virtue of a bearing, and the front end cover is fixed together with the stator and the rear end cover. Valve plate distribution is adopted by the inner curvilinear low-speed large-torque water hydraulic motor; the leakage of the matched fluid and the rotor is decreased by virtue of the combined springs, and the worn interval can be automatically compensated; an equal accelerated movement law curve is adopted by the inner curved surface of the stator, so that the low-speed stability under a multi-effect structure is ensured.

Description

technical field [0001] The invention belongs to the field of hydraulic technology, and relates to a motor with natural water (including seawater and fresh water) as the medium, in particular to an inner curve low-speed motor with replaceable wear-resistant discs added to reduce the direct wear of the rotor pair of the distribution fluid. High torque water hydraulic motor. Background technique [0002] The low-speed high-torque water hydraulic motor is a water hydraulic actuator that uses fresh water or seawater as the working medium and can convert water pressure energy into mechanical energy to achieve continuous rotary motion. It plays an important role in the water hydraulic system. However, due to the special properties of water such as low viscosity, poor lubricating performance and high gasification pressure, the development of water hydraulic components faces many problems. Such as friction and wear between friction pairs, corrosion of parts, reduction of leakage and...
