Reducer and upper box thereof

Abstract

The invention provides an upper box of a reducer, wherein a first oil pocket and a second oil pocket are respectively arranged on two inner side walls in a width direction of the upper box; at least one of two inner side walls in a length direction of the upper box is provided with a side oil pocket; and a side oil way communicated with a bearing seat of the upper box. Lubricating oil is collected through the first oil pocket, the second oil pocket and the newly-arranged side oil pocket so as to increase collection and utilization amount of lubricating oil; and oil is conveyed to position of the bearing seat through the side oil way communicated with the bearing seat arranged on the upper box so as to improve lubricating and cooling effects at the position of the bearing seat. Particularly, compared with the side oil pocket arranged on only one side, two side walls in the length direction of the upper box are provided with side oil pockets so as to further increase collection amount of lubricating oil, and improve lubricating and cooling effects at the position of the bearing seat on the reducer. A reducer with the upper box further is provided by the invention.

Description

technical field [0001] The invention relates to the technical field of power transmission equipment, and more specifically, to a reducer and its upper case. Background technique [0002] The W1 series reducer is a pump reducer with a parallel shaft first-stage transmission structure. The transmission speed ratio range is 1.25-5.6, so both the high-speed shaft and the low-speed shaft of the reducer have a relatively fast rotation speed. The faster bearing rotation speed makes the reducer generate more heat when it works. When the reducer is working, in order to better cool down the bearing, the bearing needs to provide sufficient lubricating oil. The lubricating oil can lubricate the bearing on the one hand and take away the heat faster. [0003] Oil bags are set above the bearing seats on both sides of the reducer box, and there is a connected oil path between the oil bag and the outer ring of the bearing, so that the splashed lubricating oil collected by the oil bag can be...

AI Technical Summary

Problems solved by technology

[0004] The position of the oil bag in the reducer is set on the box wall on both sides of the bearing seat. Therefore, during the rotation of the reducer, only a part of the lubricating oil on the high-speed shaft or low-speed shaft can fall on the box wall after being splashed. On the oil bag, the amount of oil collected by the oil bag is not enough to fully realize the collection of splashed lubricating oil
