Lubricating device of motor bearing

Abstract

The invention relates to a motor matching device. In order to solve the technical problems that oil throwers of lubricating devices of existing motor bearings cannot prevent lubricating grease from being thrown off and waste oil grease can not discharged, lubricating devices of conventional motor bearings are improved and the innovations are that the oil thrower is a round tray with an inner hole, the thickness of the oil thrower is tapered in a radial direction outwards from a contacting contour circle of an inner sleeve of a bearing to the oil thrower, the oil thrower and a non contacting face of the bearing are in a same plane, the oil thrower and the bearing are assembled in a combining mode, a V-shaped hollow cavity is formed between the oil thrower and the bearing, the height of the oil thrower is lower than the diameter of the inner sleeve of the bearing, an annular boss is assembled on the inner wall of an outer cover of the bearing, a spigot is arranged on the inner wall of the outer cover of the bearing, and a narrow gap serving as an oil overflowing channel is formed between the outer edges of the boss and the oil thrower. The lubricating device is easy to process, convenient to install, and guarantees not only residual amount of the lubricating grease in a bearing chamber but also cleanness of the lubricating grease and discharge of the waste oil grease.

Description

[0001] Technical field [0002] The invention relates to a matching device for a motor, in particular to a lubricating device for a motor bearing. Background technique [0003] During the operation of the motor, the bearing bears the effect of axial force and radial force. The rolling element rubs against the inner and outer shell of the bearing during rotation to generate heat and wear. A certain amount of grease must be stored in the bearing chamber to lubricate the bearing And heat dissipation, the stock of grease generally does not exceed one-third of the total amount of the bearing chamber. Small motors mostly use closed bearings, and large and medium-sized motors are open bearings. It is necessary to ensure the cleanliness of grease, replenish new grease in time, and discharge waste grease after use to ensure good bearing operation. [0004] At present, common lubrication devices for motor bearings are such as figure 1 As shown, it includes a bearing 3 installed on the beari...

Problems solved by technology

However, it is found in use that since the contact surface between the oil throwing pan 4 and the bearing 3 is a vertical surface, the width of the oil seepage space 8 is too narrow, and waste grease is difficult to be discharged by the oil seepage space 8; and if the width of the oil seepage space 8 is too large Wide, because the cavity formed between the oil throwing pan 4 and the bearing 3 is very narrow, the grease may be thrown out directly from the oil seepage gap 8, resulting in excessive use of grease
