The rotary mechanism is one of the main parts of the rotation of the crane. It is usually composed of motor, reducer, clutch, brake, ring gear, large roller and other components. Its main role is to achieve rotation and transfer of cranes, let the crane rotate in the plane and reach the rotation of different directions and angles.
There are two main forms of crane rotation mechanism: one is to use a combination of motor and reducer to drive gear rotation; the other uses a hydraulic motor to drive the rotation table. Generally speaking, the former's structure is relatively simple and widely used; the latter is mainly applied to large cranes and high -ton bicycles because it can adapt to larger loads.
The transformer mechanism is another important part of the rotation of the crane. It is mainly composed of hydraulic motors, oil cylinders, and sales shafts. Its main role is to achieve a heavy machine change, which translates the crane along the cantilever, so that the range of the boom is wide.
The working principle of the transformer mechanism is to drive the oil cylinder through the hydraulic motor, and the crane boom moves along the cantilever, thereby changing the position of the hook. Adopting a variable -amplitude mechanism can change the scope of the boom within a certain range and achieve more flexible operations of the crane.
The slewing reducer for cranes includes a housing, a brake, an output shaft, a first-stage planetary gear mechanism, a second-stage planetary gear mechanism, a third-stage planetary gear mechanism, etc., The shell includes a base body, an intermediate cylinder and a sleeve, The brake includes a coupling sleeve, a piston, a left baffle, a right baffle, a left retaining ring, a right retaining ring, a spring, an outer friction plate and an inner friction plate. The left end of the primary sun gear of the primary planetary gear mechanism is installed in the coupling sleeve Inside, the left end of the second-level sun gear of the second-level planetary gear mechanism is installed in the first-level planet carrier, and the left end of the third-level sun gear of the third-level planetary gear mechanism is installed in the second-level planet carrier. One end of the spline teeth provided on the output shaft is inserted into the center hole of the spline teeth in the third-stage planet carrier belt, and the output shaft is set on the sleeve of the housing through the bearing. This rotary reducer not only has a compact structure but also takes up little space. , and the transmission torque is large.
