The bridge crane is a large-scale lifting equipment that we often see outdoors, because its function and performance is very good, so it is very popular, and many enterprises also cannot leave its use, such as port transportation and container handling, these enterprises will choose it. Today, Henan Weihua crane co,.Ltd. Will introduce the transmission gear to you.
The transmission gear of bridge crane mainly adopts the cylindrical gear actuator with helical teeth and straight teeth.In most cases, all gear assembly type are enclosed in a reducer type. Only low speed turbine stage in the gear assembly can be open type. In this case, low speed turbine stage is separate from the reducer, separately installed and enclosed by a thin case. By using the reducer, grouping mechanism combination can be achieved and also creates advantageous conditions for the interchangeability of components.
The job content of wheel gearing and the overall size and weight of reducer largely depend on distribution of the total transmission and the choice of material and major parameter of the wheel gearing. Therefore, when designing bridge crane, the reducer must reach reasonable distribution of total transmission ratio, choose reasonable material combination of gear and corresponding manufacturing process and reasonable transmission parameter.
The tow stage and three stage gear reducer used in the bridge crane mechanism is usually made of three or four-axis, that is made of expansion form. Because enough total distance of shaft center can be get in such structure., so it is permissible to place the end of output shaft and inlet shaft on the same side, which is very important. Because in most cases, the motor and drum of bridge crane are placed on same side of reducer.
To sum up, this is the introduction of the transmission gear of the overhead crane, if you want to purchase the equipment, please contact Henan Weihua Crane Co,.Ltd.
