Abstract

The utility model discloses a radial sealing device for bull gear of grinding machine having advantages as simple structure, economic, and applicable. The device comprises a gear guard mounting on a bull gear, a rubber sealing device is provided at the connection part between the gear guard and the bull gear.

Description

A kind of grinding machine gearwheel apex combustion seal

Technical field

The utility model relates to the device of the gearwheel radial seal that a kind of grinding machine uses.

Background technique

At present, mill all adopts the common and braid wool felt seal with the apex combustion seal of gearwheel; The major defect of this sealing means is: because wool felt do not have elasticity, cause seal failure then so it is easy to wearing and tearing, maintain loaded down with trivial detailsly, need to regularly replace.

Summary of the invention

The purpose of this utility model is exactly in order to address the above problem, and a kind of grinding machine gearwheel apex combustion seal with advantage such as simple in structure, economical and practical is provided.

For achieving the above object, the utility model adopts following technological scheme:

A kind of grinding machine gearwheel apex combustion seal, it comprises gear cover, and gear cover is installed on the gearwheel, and described gear cover and gearwheel connecting part are provided with rubber sealing device.

Described rubber sealing device comprises the fixed plate that is positioned at the gearwheel outside, and fixed plate is connected by anchor bolt nut and sealing dunnage, is provided with rubber ring between fixed plate and sealing dunnage.

The utility model adopts the elastic caoutchouc circle to replace the common and braid wool felt.Because when installing, the elastic caoutchouc circle has individual amount of deformation, meeting and gear flank sealing cylinder has individual impacting force when user mode, and this provides better sealing; In use, the elastic caoutchouc circle also can wear and tear, but owing to begin it individual amount of deformation is arranged, and the wearing and tearing in working life still can not cause sealing the disappearance of impacting force and cause sealing to reduce.

The beneficial effects of the utility model are: simple in structure, easy to use, easy to maintenance, and long service life.

Description of drawings

Fig. 1 is the schematic cross-section of common and braid wool felt seal in the prior art;

Fig. 2 is the structural representation of seal with elastometic washer;

Fig. 3 is the partial enlarged drawing of Fig. 2.

Among the figure: 1, gear cover, 2, the sealing dunnage, 3, rubber ring, 4, fixed plate, 5, anchor bolt nut, 6, gearwheel, 7, the wool felt collar.

Embodiment

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

Among Fig. 1, prior art is a mounting teeth wheel cover 1 on gearwheel 6, is wool felt collar 7 between the two.

Among Fig. 2, Fig. 3, the utility model comprises gear cover 1, and gear cover 1 is installed on the gearwheel 6, is provided with rubber sealing device in gear cover 1 and gearwheel 6 connecting parts.

Rubber sealing device comprises the fixed plate 4 that is positioned at gearwheel 6 outsides, and fixed plate 4 is connected by anchor bolt nut 5 and sealing dunnage 2, is provided with rubber ring 3 at fixed plate 4 and 2 of dunnages of sealing.

Sealing dunnage 2 is designed an angle with gear cover 1 side plate; Rubber ring 3 adopts wear resistant elastic material, is formed by the rubber tape coiling that has a tapering, and this tapering and sealing dunnage 2 cooperate with the angle of gear cover 1 side plate, guarantees the in advance impacting force of rubber ring 3 installation backs to gearwheel 6; Fixed plate 4 plays the fixedly effect of rubber ring 3, can conveniently take away during dismounting and remove rubber ring 3; Design has the oval hole on rubber ring 3 simultaneously, not only plays fixing effect, and rubber ring 3 is moved inward along the oval hole.

The utility model can be used for grinding machine is carried out radial seal with gearwheel.

For the consideration of sealing, rubber ring is in elastic deformation in use, and its impacting force to gearwheel has guaranteed sealing radially.After the rubber ring wearing and tearing, impacting force will be decreased to very little, can not guarantee sealing, at this moment, can move inward rubber ring, still can make it be in elastic deformation along the oval hole on the rubber ring, so improve the utilization ratio of rubber ring, increased the working life of whole rubber ring.
