CN202082291U - End cover of bearing box of fan - Google Patents

Abstract

The utility model discloses an end cover of a bearing box of a fan, oil scraping tanks are arranged in the end cover, and an oil discharge tank communicated with the oil scraping tanks is axially arranged in the end cover. In the utility model, the oil discharge tank is arranged at the oil scraping tanks, the oil in the oil scraping tank is returned into the bearing box through the oil discharge tanks, so that the oil leakage phenomenon of the sealed end cover can be eradicated, the sealability is good, the oil lack phenomenon of an oil tank, caused by the oil leakage, can be avoided, and the lubrication effect of a bearing can be improved.

Description

A fan bearing box end cover

technical field

The utility model relates to an end cover of a fan bearing box.

Background technique

Usually, the fan bridge end cover adopts the traditional sealing method. Its structure is that the bearing end cover is added with a small gland, and the large end cover is used to fasten the outer ring of the bearing to provide axial preload for the outer ring of the bearing. The lubricating oil of the bearing box is used for sealing, and it is also the fixed base of the small end cover. The small end cover is used to seal the radial gap of the transmission shaft. The inner pressure felt sealing material, with the aging of the equipment, its poor sealing performance is increasingly exposed. . It is manifested as oil leakage and oil seepage at the bearing end cover, and the continuous loss of lubricating oil will pollute the environment on the one hand; on the other hand, it will cause the risk of lack of lubricating oil and affect the normal operation of the equipment.

Utility model content

The purpose of the utility model is to provide a fan bearing box end cover with good sealing performance.

For achieving the above object, the technical scheme that the utility model adopts is:

The utility model relates to an end cover of a fan bearing box. An oil scraping groove is arranged in the end cover, and an oil unloading groove communicating with the oil scraping groove is arranged in the end cover along the axial direction.

There are at least two scraping grooves.

The utility model adopts the structural design of setting an oil unloading groove at the oil scraping groove, which has the following advantages: 1. The oil in the oil scraping groove returns to the bearing box through the oil unloading groove, which can prevent the oil leakage phenomenon of the sealing end cover, has good sealing performance, and avoids oil leakage and damage The phenomenon of lack of oil in the oil tank improves the lubrication effect of the bearing; 2. Effectively guarantees the good lubrication of the high-speed running bearing, avoids the occurrence of bearing locking, eliminates hidden dangers of equipment safety, and ensures the normal operation of the equipment; 3. In routine When checking the bearing, it is convenient to disassemble the bearing end cover, reduce labor intensity and improve work efficiency; 4. No need to add sealing material, avoid heat generated by friction and wear between the sealing packing and the shaft, carbonize the sealing material, and reduce oil pollution; 5 .Ensure that the equipment environment is clean and hygienic.

Fig. 2 is the left view of Fig. 1;

Fig. 3 is an assembly drawing when the utility model is in use.

Detailed ways

As shown in Figure 1 and Figure 2, a fan bearing box end cover 1, the end cover 1 is provided with an oil scraping groove 2, and the end cover 1 is provided with an oil discharge groove 3 in communication with the oil scraping groove 2 along the axial direction. There are three oil scraping grooves 2, and the oil scraping grooves 2 are connected through the oil unloading groove 3.

As shown in Figure 3, when in use, the end cover 1 passes through the transmission shaft 4 and is installed on the bearing box, and the transmission shaft 4 is fitted with a carbon steel oil retaining ring 5, which acts as a primary seal. The oil groove 3 returns to the bearing box, and the sealing can be realized without adding sealing materials and small glands, and the sealing effect is good.

Claims (2)

1. An end cover of a fan bearing box, the end cover is provided with an oil scraping groove, and it is characterized in that an oil unloading groove communicated with the oil scraping groove is arranged in the end cover along the axial direction. 2. The end cover of the fan bearing box according to claim 1, wherein there are at least two oil scraping grooves.
