Technical Field

The invention relates to a roller.

Background

The escalator is widely applied to shopping centers, subway stations, airports, hospitals and the like. The roller is used as a running part and is widely applied to escalators. For indoor escalators, existing roller bearing sealing solutions have provided adequate protection. When the roller is applied to an outdoor escalator, the roller bearing may contact rainwater, sand, dust, etc., and thus the bearing may be easily rusted if there is no additional protection. The failed roller bearing can reduce the service life of the escalator and even cause accidents.

Disclosure of Invention

The invention provides a roller, which aims to solve the problem of poor sealing of the conventional roller bearing under the outdoor application condition.

In order to solve the technical problems, the technical scheme adopted by the invention is as follows:

the utility model provides a roller, includes can the suit at epaxial bearing, wheel hub, outer lane and sealing washer, wheel hub suit is on the bearing, outer lane and wheel hub fixed connection, the sealing washer cladding is on the bearing and coaxial with the bearing, characterized by, sealing washer one end with wheel hub connects, and the other end is provided with a plurality of lips, a plurality of lips with the surface butt of axle.

One end of the sealing ring is fixedly connected with the hub.

One end of the sealing ring is fixedly connected with the hub into a whole by a laser welding method.

And annular grooves are arranged on two sides of the sealing ring.

The sealing ring is made of soft engineering plastics.

The sealing rings are symmetrically arranged on two sides of the bearing.

The number of the lips is three, namely an outer lip, a middle lip and an inner lip.

The outer side surface of one end of the sealing ring connected with the hub is provided with a chamfer or a fillet, and the chamfer or the fillet and the hub form a groove convenient for welding.

The section of the ring groove is V-shaped.

After the technical scheme is adopted, one end of the sealing ring is connected with the hub, the other end of the sealing ring is provided with a plurality of lips, and the lips are abutted to the outer surface of the shaft. The outer surface butt of a plurality of lips and axle can play the sealed function of multilayer, has improved sealing performance greatly, reduces the frictional force with the axle simultaneously. One end of the sealing ring is fixedly connected with the hub, and particularly, one end of the sealing ring is fixedly connected with the hub into a whole through a laser welding method. The sealing performance of the sealing ring is further improved. The two sides of the sealing ring are provided with ring grooves with V-shaped sections, so that the deformation in the welding process can be compensated.
