Abstract
The utility model relates to a gear box body for rail transit. A main shaft hole, a transition gear shaft mounting hole and a high-speed gear shaft mounting hole are formed in parallel in the box body from front to back. A hanger rod mounting seat is also arranged on the box body. The box body consists of an upper box body and a lower box body. The high-speed gear shaft mounting hole is formed in the upper box body. The main shaft mounting hole and the transition gear shaft mounting hole are positioned in the joint surface of the upper and lower box bodies. The hanger rod mounting seat is positioned at the front end of the lower box body. A maintenance observation hole is formed at the top of the upper box body between the high-speed gear shaft mounting hole and the main shaft mounting hole. A cover plate is arranged on the maintenance observation hole. Catcher grooves are formed on the two sides of the maintenance observation hole. Each catcher groove is divided into three independent lubricating oil grooves by grids. The lubricating oil grooves supply lubricating oil to support bearings on a main shaft, a transition gear shaft and a high-speed gear shaft through oil delivery pipes. An oil charging hole, an oil drain hole and an oil pointer mounting hole are formed in the lower box body.

A) described casing is made up of upper box and lower box, and the high speed gear shaft mounting hole is located on the upper box, and the center line of spindle mounting hole and transition gear axle mounting hole is positioned at the junction plane of upper box and lower box, and described suspension rod fitting seat is positioned at the front end of lower box;
B) upper box is provided with the maintenance peep hole, and the cover plate that coupling is installed on the peep hole is overhauled at the upper box top of maintenance peep hole between high speed gear shaft mounting hole and spindle mounting hole;
C) both sides of maintenance peep hole are provided with oil trap, and each oil trap is cut apart the back by grid and formed three independently oil grooves, and the spring bearing that their transport pipe through the bottom are respectively corresponding on main shaft, transition gear axle and the high speed gear shaft provides lubricant oil;
D) oil hole, drain oil and oil ga(u)ge mounting hole all are located at lower box.
In the utility model: the upper surface of lower box middle hanger fitting seat and last lower box junction plane are in same plane.
In the utility model: oil hole, drain oil and oil ga(u)ge mounting hole are the tapped hole of same size.
In the utility model: the height of each grid is positioned at same horizontal plane in the oil trap, and is lower than the frame of oil trap periphery; The adjacent setting with the oil ga(u)ge mounting hole of oil hole, they are positioned at lower box corner and at right angles arrange.
The advantage of the utility model is: it is parallel with last lower box junction plane to observe the cover plate fitting seat, can when processing upper box junction plane, make things convenient for the clamping of casing, reduces the input of processing tool; The screw specification is unified in oil hole, drain oil and oil ga(u)ge mounting hole three holes, reduces the number of times of changing cutter, improves work efficiency; The suspension rod fitting seat is arranged on lower box; Optimized the stressed fulcrum of gear-box, avoided the gear-box deadweight to need to rely on and gone up the disadvantage that the lower box clamping bolt bears, simultaneously; Suspension rod installation seat surface and last lower box junction plane are on same plane; Can when processing lower box junction plane, together the suspension rod attachment face be processed, avoid the secondary clamping, improve the positional accuracy that suspension rod is installed seat surface; The oil hole of lower box is adjacent with the oil ga(u)ge mounting hole, in the casing corner layout that meets at right angles, has so just made things convenient for the variation that when refueling, can directly see oil level dynamically; The upper box both sides respectively are provided with oil trap; Be provided with the independent oil groove corresponding in the oil trap with each spring bearing; Give independently oil groove by reallocation after the oil trap oil-collecting, like this, can guarantee the spring bearing balanced lubrication of main shaft, transition gear axle and high speed gear shaft simultaneously.
