Split impeller-type hydraulic swinging-motor shell and fixed vane connection method

Abstract

A method for connecting a shell of a split vane type hydraulic swing motor to a fixed vane in the technical field of mechanical engineering, wherein: the inner cylindrical surface of the shell is attached to the outer cylindrical surface of the fixed vane; In the complete cylindrical pin hole formed by the half pin hole and the axial half pin hole on the outer cylindrical surface of the fixed vane; the left spring is placed at the bottom of the left threaded hole on the fixed vane, and the left combined gasket is placed on the countersunk seat of the left through hole on the shell , the left inner hexagonal screw passes through the left combined gasket and the left through hole and screwed into the left threaded hole on the fixed blade, the lower end of the left hexagonal screw head presses the left combined gasket tightly on the countersunk seat of the left through hole on the shell , the right spring is placed at the bottom of the right threaded hole on the fixed vane, the right combined gasket is placed on the countersunk seat of the right through hole on the shell, the right hexagon socket screw passes through the right combined gasket and the right through hole, and is screwed into the fixed vane In the right threaded hole, the lower end surface of the head of the right hexagon socket head cap screw presses the right combination gasket tightly on the countersunk seat of the right through hole on the housing.

Description

technical field [0001] The invention relates to a method in the technical field of mechanical engineering, in particular to a method for connecting a shell of a split vane type hydraulic swing motor and a fixed vane. Background technique [0002] The split vane hydraulic swing motor parts are easy to process and have excellent motion performance. It can be used as the actuator of a high-performance motion servo system in conjunction with an electro-hydraulic servo valve. It is widely used in experimental equipment such as flight simulation turntables and load simulators. . [0003] After searching the existing technical documents, it was found that "Machining and Measurement of the Integral Shell Shaft Assembly of Hydraulic Motor" (Electronic Mechanical Engineering, 1999, 79(3): 55-57) mentioned that the split-type vane hydraulic swing motor can be The shaft pin thread connection is adopted, the pin hole with countersunk head is processed on the shell, the pin hole with thr...

Problems solved by technology

[0003] After searching the existing technical documents, it was found that "Machining and Measurement of the Integral Shell Shaft Assembly of Hydraulic Motor" (Electrical Mechanical Engineering, 1999, 79(3): 55-57) mentioned that the split-type vane hydraulic swing motor can be The shaft pin screw connection is adopted, the pin hole with countersunk head is processed on the shell, the pin hole with thread at the bottom end is processed on the stator, and the stator and the shell are connected together with the screw with pin; but due to cutting during the working process Due to the influence of stress, the screw breaks

In practical application, another problem of the threaded connection of shaft pins in the above-mentioned documents is found: there are gaps between the stator and the housing, and between the screws and the housing. When the motor is working, the oil leaks along the above-mentioned gaps, and an additional sealing structure must be added to prevent Leakage
