Latent oily electric screw bar pump reduction gear with oil storage function

The utility model provides a latent oily electric screw bar pump reduction gear with oil storage function, includes reduction gear head, double reduction mechanism, intermediate head, transmission shaft assembly, spline housing, one -level reduction gears, input shaft, reduction gear seat. The reduction gear head in order with double reduction mechanism, intermediate head, elementary reduction gears, reduction gear seat interconnect, double reduction mechanism upper portion is connected with upper portion reducing spline housing, and the lower part is connected through intermediate head, transmission shaft assembly, spline housing and one -level reduction gears, on the transmission shaft assembly of one -level reduction gears lower part in order the erection joint have bearing, spring, pressure disk, seal receptacle, bush and lower part reducing spline housing. The utility model discloses a two -stage speed reducer structure to through the leakage that sealed between pressure disk and the seal receptacle had avoided the inside lubricating oil of reduction gear to produce when the partition, have that the speed reducing ratio is big, high transmission efficiency, save lubricating oil, reduce characteristics such as on -the -spot oiling activity duration, extensively use in the latent oily electric screw bar pump assembly of various models.
