introduction：The short answer is to reduce the speed，Increase torque，Inertia reduction Gear reducer It is the use of all levels of gear transmission to achieve the purpose of reducing speed.The reducer is composed of gear pairs at all levels.For example, using small gears to drive large gears can achieve a certain goal of deceleration,Then adopt the multi-level structure,You can significantly reduce the RPM. Gear reducer is generally used for low speed and high torque transmission equipment，Knob motor.The power of an internal combustion engine or other high-speed operation is decelerated by meshing large gears on the output shaft with fewer teeth on the input shaft of the reducer，Regular speed reducers will also have them

introduction： bearing[bearing:bearing（“Bearing”，Japanese person“Axial receptor”）It is a part that holds and reduces the friction coefficient of load during mechanical transmission。Can also be said，When other parts move relative to each other on the shaft，A device used to reduce the coefficient of friction during power transmission and to keep the center of the shaft fixed。]The ultimate axial carrying capacity： 1、Deep groove ball bearings are under simple axial load，The axial load should generally not exceed0，5C0The value of。 2、Small bearing（Inside diameter approx12Within a millimeter）And light series bearings（straight

introduction：Skeleton oil seal is relatively simple，There are usually three parts：Oil seal body、Reinforced skeleton and self-tightening coil springs。The sealing body is divided into the bottom according to different parts、loin、Cutting edge and sealing lip, etc。A skeleton is like a steel bar inside a concrete member，Play a strengthening role，And the oil seal can maintain shape and tension。usual，Skeleton oil seal in the free state，Its inner diameter is smaller than the shaft diameter，That has a certain“Magnitude of interference”。therefore，When the oil seal is loaded into the oil seal seat and shaft，The pressure of the edge of the oil seal and the contraction force of the self-tightening helical spring produce a certain radial tightening force on the shaft，After a period of running，The pressure will quickly decrease or even disappear

introduction： What to do when the electric forklift stops driving Because the driving speed and reversing of the battery forklift truck are achieved by changing the current size and current direction of the driving machine，So it doesnt have a mechanical clutch，Use the 逨 directly（Electric throttle）Controls：Use the direction switch to change the direction of the forklift（Forward or backward）The drive motor has no idle speed，Once the drive motor is turned，Forklift truck start：The speed is controlled by the accelerator：Working device of electric forklift truck（Fork lift and tilt）The operation method is the same as that of the internal combustion forklift truck。
