Choice of Reducers for Crawler Cranes
(1)The reducer of crawler crane is usually a horizontal reducer, parallel axis, horizontal points, base installation (part used type), the box for the steel plate welding structure, all gears for carburizing hardening hardened tooth surface and grinding teeth.
(2) The box should have enough rigidity to ensure that the deformation caused by loading does not affect the meshing of gears.
(3) Good lubrication and heat dissipation conditions to ensure that the temperature rise under the continuous work does not exceed the specified temperature
(4) According to the lifting mechanism layout type can be used one or two reducer. When selecting or calculating, attention should be paid to the torque and radial force of the external load of the output shaft.
(5) At the bottom of the gearbox set to put Oil Yan, in order to discharge the water in lubricants, or in the replacement of Sirun can be the old Sirun exhaust. A check hole is arranged above the gearbox to check the condition of each tooth surface and have a breathable cap to keep the inside and outside of the atmosphere pressure is equal to prevent the deceleration box working when the temperature rise caused by internal pressure to increase the oil leakage and infiltration.
