Technical Field

The invention relates to a speed reducer, in particular to an oil groove lubrication closed bearing speed reducer.

Background

The high-speed rotating shaft of the existing speed reducer has high rotating speed, and the lubricating bearings with good performance are uniformly distributed in the oil leakage and oil injection lubricating modes which are adopted in the prior art, so that the bearings are easy to wear and short in service life, and the service performance of the speed reducer is seriously influenced.

Disclosure of Invention

The invention provides an oil groove lubrication closed bearing speed reducer which is simple in structure, can effectively lubricate a bearing of a high-speed rotating shaft, prolongs the service life of the bearing and ensures the use performance of the speed reducer.

The technical scheme adopted by the invention is as follows: the utility model provides a lubricated closed bearing speed reducer of oil groove, includes box, lower box, high-speed rotation axis, oil inlet, oil-out, and oil inlet, oil-out set up its characterized in that on upper and lower box respectively: two ends of the high-speed rotating shaft are supported on the lower box body through the bearing with the oil hole and are packaged by the upper box body, a circle of oil groove is arranged on the outer circumference of the bearing with the oil hole, a plurality of oil holes are uniformly distributed at the bottom of the oil groove around the circumference of the bearing, an oil inlet channel is arranged on a bearing seat of the high-speed rotating shaft, an oil inlet is communicated with the oil inlet channel through an oil pipe, and the oil inlet.

The oil inlet channel comprises an oil inlet buffer groove, an axial channel, a radial channel and an oil plug, the oil inlet buffer groove is arranged on the outer circumference of the inner side of the oil hole bearing, the oil pipe is connected to the oil inlet buffer groove, the axial channel is axially arranged along the oil hole bearing, the radial channel is radially arranged along the oil hole bearing and communicated with the axial channel, the axial channel is used for packaging the oil plug on the opening of the outer side surface of the oil hole bearing, and the radial channel is connected with the oil groove.

According to the invention, the lubricating oil is delivered to the oil inlet buffer groove on the bearing seat through the oil pipe by the oil inlet, the lubricating oil is sequentially delivered to the oil groove of the bearing with the oil hole through the axial channel and the radial channel, and then delivered to the bearing with the oil hole through the oil hole at the bottom of the oil groove for lubrication, the lubricating oil finally falls into the lower box body and is discharged through the oil outlet, the bearing with the oil hole of the high-speed rotating shaft is fully lubricated, the service life of the bearing is prolonged, and the use performance of the speed reducer is ensured.
