Abstract

The invention discloses a multi-directional bearing oil discharge structure without stopping the motor, which includes a bearing outer cover. There are three oil discharge holes on the bearing outer cover: the bearing outer cover is originally tapped with screw holes for assembling nuts at the bottom, and then A screw hole is respectively drilled on both sides of the lower part of the bearing outer cover to be used for assembling the screw rod and the connecting pipe. When in use, the shaft extension end can discharge oil from these three holes without stopping the machine, and the non-shaft extension end, that is, the windshield end, can drain oil from the screw holes on the two sides without stopping the machine. If it is convenient to remove the windshield, the non-shaft extension end can also be Realize non-stop oil discharge from three directions, and the grease can be discharged in time to prevent it from deteriorating and hardening, which is conducive to the replenishment of new grease, improves work efficiency and prolongs the service life of the motor.

Description

A structure that can discharge oil from bearings in multiple directions without stopping the motor

technical field

The invention relates to a YE2, YE3, YE4-315~355 small motor, Y3-355~450 low-voltage high-power motor and other types of motors, which can discharge oil from multi-directional bearings without stopping, and belong to the technical field of motors.

Background technique

In the operation of YE2, YE3, YE4-315~355 small motors, Y3-355~450 low-voltage high-power motors, etc., the oil is generally drained through the oil drain hole opened at the bottom of the motor bearing cover. This oil drain method There are two problems: the one is that the operation needs to be shut down, that is, shut down earlier, then take off the motor fan cover, and then drain the oil. Production will be delayed during shutdown, and the labor intensity is high, which seriously affects production efficiency. If the oil is not drained for a long time, the grease on the bearing outer cover will accumulate more and more, and will deteriorate and harden, affecting the injection of new oil and affecting the lubrication of the bearing. It may even burn out the motor; the second is that the separate oil discharge at the bottom is difficult to discharge the waste oil in time.

Contents of the invention

In view of the above problems in the prior art, the purpose of the present invention is to provide a structure in which the motor can discharge oil from bearings in multiple directions without stopping the motor, so as to realize oil discharge in multiple directions without stopping the motor.

In order to achieve the above object, the technical solution adopted by the present invention is: a structure in which the motor can discharge oil in multiple directions without stopping the motor, including the bearing outer cover, and the bottom of the bearing outer cover is tapped with a screw hole for assembling the nut. It is characterized in that the bearing The two sides of the lower part of the outer cover each have a screw hole for assembling the screw rod and the connecting pipe respectively.

There is a gap at the top of the part where the above-mentioned oil discharge pipe extends into the outer cover of the bearing. Facilitates grease entry into the oil drain for easy extraction.

An operating handle is welded on the above-mentioned nut. It is convenient to loosen or tighten the nuts, saving effort.

Compared with the prior art, the beneficial effect of the present invention is that, in addition to retaining the original bottom oil drain hole (that is, the screw hole at the bottom of the bearing outer cover), two screw holes are added at the lower parts of both sides of the bearing outer cover, That is to say, there are three oil drain holes in total. The shaft extension end can discharge oil from these three holes without stopping the machine, and the non-shaft extension end, that is, the fan cover end, can drain oil from the two side screw holes without stopping the machine. If it is convenient to take off the fan cover, it is very convenient. The shaft extension end can also realize non-stop oil discharge from three directions, and the excess grease can be discharged in time, effectively preventing it from deteriorating and hardening, which is conducive to the replenishment of new grease, which improves the working efficiency and prolongs the service life of the motor .

detailed description

Now in conjunction with accompanying drawing, the present invention will be further described. Obviously, the invention is not to be restricted to the described embodiments thereby. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention. It should be noted that when a component is said to be “fixed” to another component, it may be directly on the other component or there may be an intervening component. When a component is considered to be "connected" to another component, it may be directly connected to the other component or may be an intervening component that exists at the same time. The terms "left", "right", "front", "rear" and similar expressions used in this specification are only for the purpose of illustration. The following examples do not indicate the model, size, condition, according to the conventional method, or Choose according to the product manual.

As shown in Figures 1-5, the structure of the present invention, which can discharge oil from bearings in multiple directions without stopping the motor, includes a bearing outer cover 1, the lower part of the bearing outer cover 1 is wider, and a screw is tapped on both sides of the lower part of the bearing outer cover 1. The holes are used to assemble the screw rod 2 and the connecting pipe 5 respectively, and the screw holes on both sides of the bearing outer cover 1 are arranged oppositely, plus the screw holes used for assembling the nut 3 at the bottom of the original bearing outer cover 1, there are three screw holes (i.e. Oil outlet), wherein the oil drain pipe 4 is inserted into the connecting pipe 5 and the oil drain pipe 4 is fixed with the connecting pipe 5 by bolts, and the oil drain pipe 4 extends into the top of the bearing outer cover 1 with a gap 4.1.

An operating handle 7 is welded on the nut 3, which is convenient for unscrewing or tightening the nut and saves effort.

When applied, the structure of the present invention is applied in the front bearing outer cover 1.1 and the rear bearing outer cover 1.2 at the same time to realize front oil discharge and rear oil discharge. The lubricating grease used for the motor bearing is added through the grease nipple 9, and enters the bearing 12 through the end cover 10 and the inner cover 11. After the motor runs for a period of time, a lot of lubricating grease will remain in the bearing cover 1 (including the front bearing cover 1.1 and the rear bearing cover 1.2). When cleaning, you can loosen the bolt 6 and take out the oil discharge pipe 4 to take away excess lubricating oil. After you can also loosen the screw rod 2, use the oil discharge pipe 4 or a spare oil discharge pipe to insert the oil discharge on the opposite side. At the end of the shaft extension, the nut 3 with the operating handle can also be loosened, and the oil can be drained with the oil drain pipe 4. Through the present invention, the oil can be discharged in time through the oil discharge pipe to prevent it from deteriorating and hardening, which is beneficial to the timely replenishment of the oil and forms a virtuous cycle of the oil.
