Embodiment Construction

[0007] Such as figure 1 , figure 2 As shown, the present invention is a compound gear motor generator, which is composed of a motor assembly and a power generation assembly. The pinion gear 5, the internal gear 8, the first motor side plate 9, the second motor side plate 16 and the crescent The body 18 constitutes a closed volume, and the oil suction chamber and the oil pressure chamber are separated by the crescent body 18. The pinion 5 is connected with the pinion shaft 6 through the round key 17, and the crescent body 18 is installed between the pinion 5 and the internal gear 8. A spring 4 is installed between the motor cover 1 and the baffle 3, and the baffle 3 is in direct contact with the first motor side plate 9, so that the first motor side plate 9 and the second motor side plate 16 can align the internal gear 8 and the pinion. 5, the pinion shaft 6 is supported on the first motor side plate 9, the second motor side plate 16 and the housing 2 through the first small ...

Abstract

Disclosed is a composite gear motor generator. The composite gear motor generator is characterized in that a pinion (5) is connected with a pinion shaft (6) through a round key (17); a crescent body (18) is mounted between the pinion (5) and an inner gear (8); a spring (4) is mounted between a motor cover plate (1) and a baffle (3); the baffle (3) is in direct contact with a motor side plate (9),so that the motor side plate (9) and the motor side plate (16) can tightly press the inner gear (8) and the pinion (5); the pinion shaft (6) passes through a small bearing (7); a small bearing (15) supports the motor side plate (9), the motor side plate (16) and the shell (2); the inner gear (8) is supported on the shell (2) through a large bearing (11) and a large bearing (12); a coil (13) in a power generation assembly is installed between the large bearing (11) and the large bearing (12) and is fixed with the shell (2); and a permanent magnet (14) is fixed with the inner gear (8).

Description

technical field [0001] The invention relates to hydraulic energy recovery technology, especially gear motor generator technology. Background technique [0002] Energy loss is a non-negligible part of the hydraulic system. On page 54 of Volume 46, No. 10 of "Machine Tools and Hydraulics", the article "Research on Energy Recovery System Based on Electro-hydraulic Coordinated Hydraulic Excavator under Compound Action Conditions" was published. This article proposed an accumulator-hydraulic The electro-hydraulic coordinated energy recovery system of the motor-generator hydraulic excavator realizes the energy recovery during the compound action of the excavator arm and rotation. The hydraulic motor is an independent hydraulic component, which needs to drive the generator through the output shaft to form a hydraulic motor-generator unit to work. The installation and use of the hydraulic motor-generator unit needs to cooperate with couplings, mounting brackets and other devices. ...
