Problems solved by technology

Since there is no specific standard equipment, the types of conveyor belt power transmission mechanisms are various and varied. At present, "motor + reducer" and "motor + (speed-adjustable) hydraulic coupling + reducer" are mostly used at home and abroad. And other technical forms, there are technical defects such as large structural volume, difficult reversing, inconvenient adjustment, and difficult starting.

Embodiment 2

[0047] The present invention also relates to a hydromechanical planetary reversing transmission method, based on a hydraulic mechanical planetary reversing transmission device in Embodiment 1, to realize the switching output of forward gear, neutral gear and reverse gear, and the specific steps are as follows:

[0048] When the forward gear needs to be realized, the pump wheel shaft drives the turbine shaft to rotate through the hydraulic transmission; when the forward gear clutch is filled with oil, the brake ring gear is locked and braked, driving the forward gear planet carrier 82 to brake, and the power passes through the forward gear sun gear 81 input, the forward gear ring gear 83 and the forward gear sun gear 81 reverse output, and the forward gear ring drives the reverse gear planetary carrier 102 to output in the same direction. to power transmission;

[0049] When the reverse gear needs to be realized, the pump wheel shaft drives the turbine shaft to rotate through t...

Abstract

The invention relates to the technical field of transmission, in particular to a hydraulic mechanical planet reversing transmission device. The hydraulic mechanical planetary reversible transmission device comprises a box body, a pump wheel shaft is arranged at the input end of the box body, and the pump wheel shaft is connected with a turbine shaft through a hydraulic transmission part; the turbine shaft is provided with a planetary speed change mechanism; a forward gear planet carrier of the planetary speed change mechanism is connected with the brake gear ring; the forward gear ring is in spline connection with the reverse gear planet carrier; the reverse gear planet carrier and an input shaft of the fixed shaft type single-stage gear transmission mechanism are of an integrated structure. The braking gear ring realizes braking through a forward gear clutch arranged on the box body; a gear ring of the reverse gear planetary pair achieves braking through a reverse gear clutch arranged on the box body.

Description

technical field [0001] The invention relates to the technical field of transmission, in particular to a hydromechanical planetary reversing transmission device and method. Background technique [0002] Transmission devices represented by marine (reversing) gearboxes and conveyor belt transmission mechanisms are typical mechanical devices that require frequent forward and reverse rotation transmission. Taking the ship transmission system as an example, during the process of ship entering and leaving the port, deceleration, and emergency avoidance, the marine gearbox needs to frequently switch between forward-neutral-reverse gears, and the rotational inertia of the propeller, tail shaft, and gear train Mechanical shock is inevitable; the marine gearbox is a typical three-shaft (input shaft, intermediate shaft, output shaft), fixed shaft constant mesh cylindrical gearbox and through two sets of wet The clutch realizes forward, idle and reverse gear switching, because of the in...
