Abstract

A sealing device of a roller system bearing end face comprises a sealing ring, an end cover, a gasket, a locating ring, an anti-dust ring, a retainer ring, a rubber oil seal and a ring seal. The locating ring and the ring seal are installed on a roller shaft, and the ring seal is provided with the rubber oil seal, the sealing ring and the retainer ring are installed in an annular gap formed between the retainer ring and an inner hole of the end cover and pressed by the retainer ring arranged on the end face of the end cover. The anti-dust ring is installed on the end cover arranged on a bearing seat through bolts. The sealing device of the roller system bearing end face can effectively perform anti-dust and oil-leakage resistant sealing on a roller system bearing, avoid pollution and leakage of grease oil, increase service life of the sealing ring and a bearing and improve operation efficiency of equipment.

Description

Roller is the bearing face seal arrangement

Affiliated technical field

It is the bearing face seal arrangement that the utility model relates to a kind of roller, is that a kind of roll-in mill is the bearing face seal arrangement with roller specifically.

Background technique

The roll-in mill has another name called roll squeezer, is the energy-conservation milling equipment of novel concrete that the mid-80 grows up, and has the high pebble mill system of all or part of alternative energy consumption, is the grinding technology new breakthrough.Roll-in mill main working parts is the roller system of a cover move toward one another, the granule materials of sending into along with roller system in opposite directions running be brought between the roller in the gap and obtain extruding and pulverize.Owing to roller is to pulverize functional part, the powder airborne dust is very big around the roller, and dust passes the bearing support end cover and gets in the bearing support, worsens the bearing Environmental Conditions, and bearing oil pollutes and wastes easily from the seal clearance leakage.Existing seal form is common oil-resistant seal ring seal form; Because roll-in milling roller long-term operation wearing and tearing seal ring, powder get into bearing support Seal cage pollution lubricating oil, shorten bearing working life; Cause oil leak simultaneously; Need periodic replacement seal ring and rolling bearing, increase the equipment user cost, reduce operation rate.

Summary of the invention

In order to improve bearing working life and operation rate, it is the bearing face seal arrangement that the utility model provides a kind of roller.This device can pair roller be that bearing effectively seals, and avoids lubricant pollution and leakage, increases seal ring and bearing working life, the raising operation rate.

The technological scheme that the utility model adopts is: a kind of roller is the bearing face seal arrangement; Form by seal ring, end cap, packing ring, positioning ring, dust ring, back-up ring, rubber oil sea, seal ring; Positioning ring and seal ring are installed on the roll shaft, and rubber oil sea is housed on the seal ring; Seal ring and packing ring are installed in the annular space of positioning ring and the formation of end cap endoporus, and are compressed by the back-up ring that is installed on the end cap end face; Dust ring is installed on the end cap, and end cap is installed on the bearing support through bolt.

The beneficial effect of the utility model is: roller be the bearing face seal arrangement effectively pair roller be the dustproof and anti-draining sealing of bearing, avoid lubricant pollution and leakage, increase seal ring and bearing working life, the raising operation rate.
