Abstract
The utility model discloses a thrust wheel sealing device comprising a thrust wheel inner sealing mechanism and a thrust wheel outer sealing mechanism. The thrust wheel inner sealing mechanism comprises a seal member and an inner end cover. The seal member penetrates through a thrust wheel shaft, is arranged at the inner end of an inner hole of a thrust wheel hub, and is located on the outer side of the thrust wheel shaft. The inner end cover covers the outer side of the seal member. The thrust wheel outer sealing mechanism comprises an outer end cover and a stop ring. The outer end cover is arranged at the outer end of the inner hole of the thrust wheel hub, the outer edge of the outer end cover is pressed against the inner side of an annular groove of the outer end of the inner hole of the thrust wheel hub, the stop ring is embedded on the outer side of the annular groove, and the inner side of the stop ring is pressed against the outer edge of the outer end cover. The outer sealing mechanism is arranged in the inner hole of the thrust wheel hub, so that the thrust wheel sealing device is simple in structure, disassembly can be completed without special tools, assembly and disassembly are facilitated, the outer end cover is not easy to collide with a hard object to damage, sealing effect is good, and cost is low.
Description
Technical field
The utility model relates to a kind of sealing arrangement, and especially a kind of track combine caterpillar wheel sealing arrangement belongs to the mechanical sealing technology field.
Background technology
Track roller is the critical component of track combine traveling gear, and track roller rolls at crawler belt, and body weight is passed to ground by crawler belt, stops crawler belt that frame is produced horizontal relative displacement.Because of work under bad environment, caterpillar wheel is for a long time in marshy land work, and its leak tightness directly influences the in-use performance of caterpillar wheel.Existing track combine caterpillar wheel sealing arrangement comprises inner seal mechanism and outside sealing mechanism, inner seal mechanism can prevent effectively that by sealing member and inner end cap muddy water or dust from entering in the caterpillar wheel bearing, outside sealing mechanism adopts side seal usually, comprise paper washer and outer end cap, earlier coat sealant on the paper washer two sides during installation, be fixed on the caterpillar wheel wheel hub outer face, by fastener outer end cap is captiveed joint with caterpillar wheel wheel hub outer face then, because fastener is worked in the muddy water environment for a long time, rust is dead easily, and installing/dismounting is loaded down with trivial details, and outer end cap protrudes from outside the caterpillar wheel wheel hub simultaneously, easy touch hard object damaged in collision during farm work, cause seal failure, caterpillar wheel is in case the dismounting maintenance just need more renew paper washer, caterpillar wheel wheel hub outer face requirement on machining accuracy is also high, has increased manufacturing cost greatly.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, good airproof performance, easy accessibility, caterpillar wheel sealing arrangement that cost is low.
The utility model is achieved by the following technical programs:
A kind of caterpillar wheel sealing arrangement, comprise caterpillar wheel inner seal mechanism and caterpillar wheel outside sealing mechanism, caterpillar wheel inner seal mechanism comprises sealing member and inner end cap, described sealing member is positioned at the caterpillar wheel bearing outside, and pass the caterpillar wheel wheel shaft and be arranged on caterpillar wheel wheelboss inner hole the inner, inner end cap is located at the sealing member outside; Described caterpillar wheel outside sealing mechanism comprises outer end cap and back-up ring, outer end cap is arranged on caterpillar wheel wheelboss inner hole outer end, the outer end cap outer rim is resisted against the circular groove inboard of caterpillar wheel wheelboss inner hole outer end, and back-up ring is inlaid in described ring slot outside, and the back-up ring inboard is pressed against on the outer end cap outer rim.
The purpose of this utility model can also further realize by following technical measures.
Aforesaid caterpillar wheel sealing arrangement, wherein said outer end cap outer rim is ledge structure, and outer end cap comprises skeleton and the caulking gum body that is fixed on the skeleton inboard, and described skeleton and caulking gum shape match, and the caulking gum body adopts nitrile rubber to make.
Aforesaid caterpillar wheel sealing arrangement, wherein said back-up ring are elastic spring.
The utility model is arranged on outside sealing mechanism in the caterpillar wheel wheelboss inner hole, and is simple in structure, need not special tool and can finish dismounting, do not have the bolt dead problem of becoming rusty, easy installation and removal, and outer end cap is not fragile, good sealing effect, cost is low.
Advantage of the present utility model and characteristics will illustrate by the non-limitative illustration of following preferred embodiment and explain that these embodiment only provide as an example with reference to accompanying drawing.
