Abstract
The utility model discloses a balancing wheel bearing seal structure of a rice wheat combine harvester, comprising a frame square pipe (1), a casing (2), a balancing wheel axle (3), a sleeve (5), an oil seal (6), a bearing (7) and a balancing wheel (8), wherein a seal groove for housing a O-shaped seal ring (4) is arranged on the end surface of the sleeve (5) far away from the casing (2) and the seal groove is a triangle groove capable of ensuring axial and radial bidirectional seal of the O-shaped seal ring (4). The seal structure with above special structure adds the seal grove on the right end surface of the sleeve to almost double the contact area of the left end of the sleeve and the casing, so as to prevent end surface from being weakened and obviously improve the stress of the sleeve and the casing; simultaneously the triangle seal groove achieves the axial and radial bidirectional seal of the O-shaped seal ring and the seal reliability is increased; simultaneously, the O-shaped seal ring is protected, the O-shaped seal ring is prevented from being cut during assembly process and the service life of the O-shaped seal ring is prolonged.
Description
Technical field
The utility model relates to a kind of rice wheat combine harvester caterpillar wheel, especially relates to the hermetically-sealed construction of this kind caterpillar wheel bearing.
Background technology
Caterpillar wheel is the parts of rice wheat combine harvester chassis portion, and effect is with the reaper net weight, passes on the crawler belt together with weight such as Cereals of gathering in the crops and fuel oils.For the caterpillar wheel bearing, because will under mal-condition, work, thus very high to the waterproof and dustproof performance demands, be to be related to the caterpillar wheel bearing key factor in service life.Present hermetically-sealed construction adopts side seal, structure shown in Figure of description 1, sleeve bears bolt preload pressure and wheel shaft and is subjected to counter pressure after curved, owing to be on sleeve and end face that sleeve pipe contacts, to process sealed groove, so reduced sleeve pressurized cross section, the sleeve channel part is deformation in compression easily, reduce groove height, the O RunddichtringO can follow the string because amount of compression is excessive, thereby reduces sealing effectiveness, structure shown in Figure of description 2 influences the in-use performance of caterpillar wheel then.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of rice wheat combine harvester caterpillar wheel bearing hermetically-sealed construction at problems of the prior art, its objective is not only to guarantee sealing property but also make the cross section of sleeve not weakened, thus the service life of assurance O RunddichtringO.
The technical solution of the utility model is this kind rice wheat combine harvester caterpillar wheel bearing hermetically-sealed construction, comprise frame square tube, sleeve pipe, supporting wheel shaft, sleeve, oil sealing, bearing and caterpillar wheel, the end face away from sleeve pipe on the described sleeve is provided with the sealed groove of placing seal ring.
Described sealed groove is to guarantee axially and the radially triangular groove of two way seal of seal ring.
Described seal ring is the O RunddichtringO.
A kind of rice wheat combine harvester caterpillar wheel bearing hermetically-sealed construction with above-mentioned special construction has the following advantages:
1. this kind rice wheat combine harvester caterpillar wheel bearing hermetically-sealed construction makes the area of contact of sleeve left end and sleeve pipe increase nearly one times by at the right side of sleeve processing sealed groove, has avoided end face weakening, and the stressed of sleeve pipe and sleeve all had clear improvement.
2. this kind rice wheat combine harvester caterpillar wheel bearing hermetically-sealed construction is by the triangle sealed groove of setting; make the O RunddichtringO reach axially and two way seal radially; increase sealing reliability; simultaneously; can protect the O RunddichtringO; cut the O RunddichtringO when avoiding assembling, prolonged the service life of O RunddichtringO.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 prior art constructions scheme drawing.
Fig. 2 is the local enlarged diagram of structure shown in Figure 1.
Fig. 3 is a structural representation of the present utility model.
Fig. 4 is the local enlarged diagram of structure shown in Figure 3.
In Fig. 1-4,1: the frame square tube; 2: sleeve pipe; 3: supporting wheel shaft; The 4:O RunddichtringO; 5: sleeve; 6: oil sealing; 7: bearing; 8: caterpillar wheel.
The specific embodiment
By the combination of structure shown in Fig. 1-2 as can be known, present hermetically-sealed construction adopts side seal, sleeve bears bolt preload pressure and wheel shaft and is subjected to counter pressure after curved, owing to be on sleeve and end face that sleeve pipe contact, to process sealed groove, therefore reduced sleeve pressurized cross section, the partly easy deformation in compression of sleeve channel, reduce groove height, the O RunddichtringO can follow the string because amount of compression is excessive, thereby reduces sealing effectiveness, influences the in-use performance of caterpillar wheel then.
Fig. 3, Fig. 4 is a structural representation of the present utility model, this kind rice wheat combine harvester caterpillar wheel bearing hermetically-sealed construction comprises frame square tube 1, sleeve pipe 2, supporting wheel shaft 3, sleeve 5, oil sealing 6, bearing 7 and caterpillar wheel 8, end face away from sleeve pipe 2 on the sleeve 5 is provided with the sealed groove of placing O RunddichtringO 4, sealed groove is to guarantee axially and the radially triangular groove of two way seal of O RunddichtringO 4, process sealed groove by right side at sleeve 5, make the area of contact of sleeve 5 left ends and sleeve pipe 2 increase nearly one times, sleeve pipe 2 and the stressed of sleeve 5 are all had clear improvement; Simultaneously, triangular groove has increased sealing reliability, simultaneously, can protect O RunddichtringO 4, cuts O RunddichtringO 4 when avoiding assembling, and has prolonged the service life of O RunddichtringO 4.
Claims (3)
1. rice wheat combine harvester caterpillar wheel bearing hermetically-sealed construction, comprise frame square tube (1), sleeve pipe (2), supporting wheel shaft (3), sleeve (5), oil sealing (6), bearing (7) and caterpillar wheel (8), it is characterized in that: the end face that described sleeve (5) is gone up away from sleeve pipe (2) is provided with the sealed groove of placing seal ring.
2. a kind of rice wheat combine harvester caterpillar wheel bearing hermetically-sealed construction according to claim 1 is characterized in that: described sealed groove is to guarantee axially and the radially triangular groove of two way seal of seal ring.
3. a kind of rice wheat combine harvester caterpillar wheel bearing hermetically-sealed construction according to claim 1 and 2, it is characterized in that: described seal ring is O RunddichtringO (4).
