Description

A waterproof bearing seat used in steel pipe anticorrosion production line

technical field

The utility model relates to the technical field of waterproof bearings, in particular to a waterproof bearing seat used in a steel pipe anticorrosion production line.

Background technique

In the anticorrosion production process of steel pipes, water cooling is an essential link, and the bearing seats in the water cooling warehouse have been poured with cooling water for a long time. Ordinary UCP series or ceramic and stainless steel bearing housings in the existing water-cooled warehouses are poured with cooling water, which can easily cause loss of lubricating oil and damage to the balls; ceramic or stainless steel series are expensive, resulting in Product costs increase.

Utility model content

Aiming at the deficiencies in the above-mentioned technologies, the purpose of this utility model is to provide a cheap and durable waterproof bearing seat suitable for steel pipe anticorrosion production lines.

The technical scheme that the utility model adopts is as follows:

A waterproof bearing seat used in a steel pipe anticorrosion production line, including a self-aligning roller bearing installed on a roller shaft, and after the self-aligning roller bearing is installed in the bearing body, the roller shafts on both sides of the bearing seat are installed with rotating shafts back to back Lip-shaped oil seal; the shaft end retaining ring affixed to the shaft head of the roller shaft and the bearing end cover affixed to the bearing body seal the shaft head side of the roller shaft, and the other side of the roller shaft is formed by the The stepped shaft and the bearing end cover fixedly connected to the bearing body are sealed.

The rotary shaft lip seal is installed on the roller shaft through a sleeve.

The utility model adopts two rotating shaft lip-shaped oil seals installed back to back, the lip-shaped oil seal near the bearing side can ensure that the lubricating grease does not leak out, and the other lip-shaped oil seal can ensure that water, dust, etc. do not enter the bearing seat. Thus, the waterproofing of the bearing seat in the water-cooled warehouse of the steel pipe waterproofing production line is completed, and the installation and disassembly are convenient, which improves the production efficiency.

The utility model has better airtightness than the traditional UCP series ordinary bearing seat, and has completed the waterproofing of the bearing seat in the water-cooled warehouse of the steel pipe waterproof production line, and is cheaper than ceramic stainless steel, etc., and can reduce production costs.

The utility model can be operated in a water-drenched environment for a long time.

In the figure: 1- shaft end fastening bolt, 2- shaft end retaining ring, 3- end cover fixing bolt, 4- rotating shaft lip oil seal, 5- pressure oil cup, 6- bearing end cover, 7- sleeve, 8-roller shaft, 9-spherical roller bearing, 10-bearing body.

detailed description

Below in conjunction with accompanying drawing, the utility model is further described.

Referring to Figures 1 and 2, a waterproof bearing seat used in a steel pipe anticorrosion production line includes a shaft end fastening bolt 1, a shaft end retaining ring 2, an end cover fixing bolt 3, a rotating shaft lip seal 4, and an oil injection cup 5. Bearing end cover 6, sleeve 7, roller shaft 8, self-aligning roller bearing 9, bearing seat body 10. After the self-aligning roller bearing 9 is installed in the bearing body 10, the rotating shaft lip-shaped oil seal 4 is installed back-to-back on the roller shafts 8 on both sides of the bearing body 10; The shaft end retaining ring 2 of the head and the bearing end cover 6 fixed on the bearing body 10 through the end cover fixing bolt 3 seal the shaft head side of the roller shaft 8, and the other side of the roller shaft 8 is formed by the step on it. The shaft and the bearing end cover 6 fixed on the bearing seat body 10 through the end cover fixing bolt 3 are sealed.

The rotating shaft lip seal 4 is installed on the roller shaft 8 through the sleeve 7, which can ensure that the metal spring of the rotating shaft lip oil seal 4 will not damage the roller shaft during long-term operation. One end of the sleeve 7 on the shaft head side of the roller shaft 8 leans against the inner ring of the self-aligning roller bearing 9, and the other end is fixed by the shaft end retaining ring 2 through the shaft end fastening bolt 1; one end of the sleeve 7 on the other side of the roller shaft 8 Lean against the stepped shaft end face of the roller shaft 8, and the other end leans against the inner ring of the spherical roller bearing 9.

The bearing housing 10 is a split structure up and down, which is convenient for installation and disassembly.

A pressure oiling cup 5 is installed on the bearing seat body 10, through which lubricating grease is injected into the bearing seat body.
