Description

Clamping type bearing sealing ring structure

Technical Field

The utility model relates to a bearing transmission machinery technical field especially relates to a card formula bearing seal circle structure of joining in marriage.

Background

The bearing is an important part in the modern mechanical equipment. Its main function is to support the mechanical rotator, reduce the friction coefficient in its motion process and ensure its rotation precision.

The sealing of the bearing can be divided into self-contained sealing and external sealing. The bearing with the seal is a device which is manufactured by the bearing with the sealing performance. Such as bearing with dust cap, sealing ring, etc. The sealing structure occupies small space, is convenient to mount and dismount and has lower manufacturing cost. The existing bearing seal has many defects, such as dust prevention, grease overflow and the like, and the sealing performance is poor.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a card formula bearing seal circle structure of joining in marriage to current problem.

The utility model discloses a realize through following technical scheme: the utility model provides a joint formula bearing seal circle structure, includes the bearing, the bearing comprises outer lane, inner circle and spin, the both sides of spin set up the circle frame of protection spin, and the distolateral symmetry and an organic whole of inner circle set up the circle ring, set up profile of tooth double flute on the outer curved surface of circle ring, set up the recess on the outer curved surface of inner circle, and the symmetry sets up outer T-slot and interior hook groove on the terminal surface of outer lane, and profile of tooth double flute, recess, outer T-slot and interior hook groove joint sealing washer's double tooth ring, bulge loop, T shape platform ring sum shackle respectively.

As a further improvement to the scheme, the inner hole of the ring and the inner hole of the inner ring have the same diameter, and the outer diameter of the ring is smaller than that of the inner ring.

As a further improvement of the scheme, the sealing ring is a circular truncated cone ring structure, a double-tooth ring corresponding to the tooth-shaped double grooves is arranged on the side wall of an inner hole of the circular truncated cone ring, a ring platform matched with a gap between the inner ring and the outer ring is arranged on an end plane of the circular truncated cone ring, a convex ring is arranged on the inner side wall of the ring platform, and a hook ring and a T-shaped platform ring are sequentially arranged outwards along the radial direction of the ring platform.

As a further improvement to the above scheme, the shackle and the T-shaped platform ring are both made of soft rubber and plastic materials.

Compared with the prior art, the utility model has the following advantages: the bearing has the advantages of simple structure, reasonable design, novel and unique thought, the T-shaped platform ring and the shackle of the sealing ring are matched with the outer T-shaped groove and the inner shackle groove of the outer ring in a clamping manner, the double-tooth ring and the toothed double groove and the groove of the inner ring are matched with the lubricating grease in a clamping manner to seal the vicinity of the ring frame, external sewage and dust are avoided entering, corrosion and corrosion of the bearing can be prevented, the service life of the bearing is prolonged, especially, a friction mode that an oil film is arranged between the rotary toothed double groove and the double-tooth ring to avoid direct contact is realized, grease overflow is prevented, the bearing is worthy of popularization, and the bearing has extremely high practicability.

Drawings

Fig. 1 is a schematic sectional view of the present invention.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

As shown in fig. 1, a snap-fit bearing seal ring structure, includes a bearing, the bearing comprises outer lane 1, inner circle 2 and spin 3, the both sides of spin 3 set up the circle frame 4 of protection spin 3, the distolateral symmetry and the integrative circle ring 7 that sets up of inner circle 2, set up profile of tooth double flute 8 on the outer curved surface of circle ring 7, set up recess 9 on the outer curved surface of inner circle 2, the symmetry sets up outer T-slot 5 and interior hook groove 6 on the terminal surface of outer lane 1, profile of tooth double flute 8, recess 9, outer T-slot 5 and interior hook groove 6 joint seal ring 10's double-tooth ring 14, bulge loop 13, T-shaped platform ring 11 and shackle 12 respectively.

As a further improvement to the scheme, the inner hole of the ring 7 and the inner hole of the inner ring 2 have the same diameter, and the outer diameter of the ring 7 is smaller than that of the inner ring 2.

As a further improvement of the scheme, the sealing ring 10 is a circular truncated cone ring structure, a double-tooth ring 14 corresponding to the tooth-shaped double grooves 8 is arranged on the side wall of an inner hole of the circular truncated cone ring, a ring platform matched with a gap between the inner ring 2 and the outer ring 1 is arranged on an end plane of the circular truncated cone ring, a convex ring 13 is arranged on the inner side wall of the ring platform, and a hook ring 12 and a T-shaped platform ring 11 are sequentially arranged outwards along the radial direction of the ring platform.

As a further improvement to the scheme, the hook ring 12 and the T-shaped platform ring 11 are both made of soft rubber and plastic materials.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
