Abstract

To the problem that the bearing seal nature exists among the agricultural machine, this patent designs a dustproof bearing frame, including bearing frame, shield and axle head gasket, the bearing frame in be provided with extension seat, holding ring, pedestal and ring channel. The bearing dust cap is clamped into the annular groove, the bearing seat, the dust cap and the shaft end gasket form a relatively sealed environment, the sealing performance of the bearing is enhanced, and the service life of the bearing is prolonged. Meanwhile, the bearing seat and the shaft end gasket also position the bearing.

Description

Dustproof bearing seat

Technical Field

The invention relates to a bearing seat, in particular to a dustproof bearing seat suitable for agricultural machinery.

Background

The bearing is an important part in mechanical equipment, and the bearing must be matched with a bearing seat for use. In agricultural machinery, a bearing is subjected to severe environmental factors such as a large amount of soil particles, a large working load, a strong impact force, insufficient maintenance conditions and the like, so that the service life of the bearing is determined by the sealing performance of the bearing.

The sealing of the bearing can be divided into self-contained sealing and external sealing. In the aspect of self sealing, a dustproof cover, a sealing ring and the like are added to improve the sealing performance of the bearing. In the aspect of external sealing, a larger lifting space is provided for improving the sealing performance of the bearing seat.

Disclosure of Invention

Aiming at the problem of the sealing performance of the bearing, the invention aims to provide a dustproof bearing seat which is characterized in that a layer of external protection is added to the bearing on the basis of sealing the bearing, so that the service life of the bearing is prolonged.

In order to solve the problems, the method is realized by the following technical scheme: a dustproof bearing seat comprises a bearing seat, a dustproof cover and a shaft end gasket. The bearing seat is provided with a positioning ring, a seat body, an annular groove and a lengthened seat, the lengthened seat is arranged at the leftmost end of the bearing seat, the positioning ring and the seat body are sequentially arranged, and the annular groove is arranged on the outer surface of the seat body close to the end surface of the right side; the dust cover is fixed through the annular groove.

The utility model discloses it is further: the bearing seat and the shaft end gasket are made of cast steel.

The utility model discloses it is further: the dustproof cover is made of rubber.

The utility model discloses it is further: the lengthening seat and the shaft end gasket have positioning and dustproof functions.

The utility model discloses it does to have beneficial effect: one side adopts the extension seat structure, and the opposite side adopts shield and packing ring cooperation to use, plays dustproof and the effect of location when satisfying bearing operating conditions, prolongs the life of bearing. The dust cover is made of rubber materials, is convenient and quick to install and detach, cannot damage the bearing seat, and is low in manufacturing cost.

Detailed Description

This will be explained in further detail below with reference to the drawings.

The dustproof bearing seat shown in fig. 1-6 comprises a bearing seat 1, a dustproof cover 2 and a shaft end gasket 3, wherein the bearing seat 1 is internally provided with an extension seat 11, a positioning ring 12, a seat body 13 and an annular groove 14, the extension seat 11 is arranged at the leftmost end of the bearing seat 1 and is sequentially provided with the positioning ring 12 and the seat body 13, and the annular groove 14 is arranged on the outer surface of the seat body 13 close to the end surface at the right side. A matched bearing is selected to be installed in the seat body 13, one side of the bearing is positioned through the shaft shoulder and the lengthening seat 11, a small gap is formed between the shaft and the lengthening seat 11, and dust is reduced under the condition of meeting working conditions; and the other side adopts a dustproof cover 2 and a shaft end gasket 3 to play roles of dust prevention and positioning. And finally, fixing the positioning ring 12 and the machine body through bolts to finish the installation.

The bearing seat 1 and the shaft end gasket 3 are made of cast steel materials, so that the high-load operation condition is met.

The dust cover 2 is made of rubber materials, is clamped into the annular groove 14 to prevent the dust cover from falling off, is convenient to mount and dismount, and cannot damage the bearing seat.

Bearing frame 1, shield 2 and axle head gasket 3 constitute a relatively sealed environment, protect the bearing, the life of extension bearing under abominable operating condition.
