Abstract
The utility model relates to a bulldozer rolling lubrication caterpillar band which comprises a plurality of caterpillar track sections, wherein adjacent caterpillar track sections are connected through pin rolls and pin bushes; the pin rolls are inserted into inner holes of the pin bushes; each pin bush comprises a fixed pin bush and a rolling pin bush; the rolling pin bushes are arranged among inner holes of the caterpillar track sections; the fixed pin bushes are arranged in the inner holes of the caterpillar track sections; seal rings A are arranged among the rolling pin bushes, the fixed pin bushes and the inner holes of the caterpillar track sections; seal rings B are arranged between the fixed pin bushes and outer holes of the caterpillar track sections; the rolling pin bushes are in clearance fit with the pin rolls. According to the utility model, traditional fixed pin bushes are classified into fixed pin bushes and rolling pin bushes; the fixed pin bushes are used as the shaft sleeves of bearings; the rolling pin bushes are meshed with driving gear tooth blocks, so that the frictional force generated by mutual extrusion is converted into rolling friction from sliding friction, the force condition is improved, and the service lives of the pin bushes are greatly prolonged.
Description
Technical field
The utility model belongs to the construction machinery and equipment crawler belt, specifically, relates to a kind of bulldozer rolling lubrication crawler belt.
Background technology
Existing bulldozer crawler belt, as described in patent CN202156468U, is connected with fixing guide by bearing pin between its adjacent chain rail joint, and the bearing pin insertion is fixedly in guide.Concrete structure is as shown in attached Fig. 1 and 2.The fixedly driving gear teeth piece of guide and bulldozer engagement, extrusion friction produces application force and drives the crawler belt rotation, drives bulldozer to travel.Fixedly guide is the relatively rotating load-carrying element of two pitch chain rails, and bears surface pressure and the force of sliding friction produced with tooth piece engagement, the fixing easy premature wear of guide, and replacement frequency is high, and maintain and replace is consuming time, has increased the operating cost of equipment.
The utility model content
For solving the problems of the technologies described above, the utility model proposes and a kind ofly reduce friction, improve guide service life, increase the bulldozer rolling lubrication crawler belt of chain rail joint ess-strain ability.
The technical solution of the utility model is: a kind of bulldozer rolling lubrication crawler belt, comprise a plurality of chain rail joints, between adjacent chain rail joint, by bearing pin, with guide, be connected, described bearing pin inserts in the endoporus of described guide, described guide comprises fixedly guide and rolling guide, and the roller bolt cover is arranged between chain rail joint endoporus, and the set pin cover is arranged in chain rail joint endoporus, the rolling guide, fixedly between guide and chain rail joint endoporus, seal ring A is set, fixedly guide and chain rail save between outer hole seal ring B are set; Rolling guide and bearing pin free-running fit.
Be provided with oil pocket in described bearing pin, the bearing pin sidewall is provided with oilhole, and the oil pocket outer end is provided with end plug.
The beneficial effects of the utility model are: the utility model by tradition fixedly guide be divided into fixedly guide and rolling guide, fixedly guide plays the function of bearing axle sleeve, the rolling guide meshes with driving gear teeth piece, make the friction force that extruding produces mutually become friction of rolling by cliding friction, improve force-bearing situation, greatly extended the service life of guide.Simultaneously, chain rail joint endoporus, the chain rail outer hole of joint and caterpillar block mounting hole, can produce than the fixing higher stress of guide of tradition, changes chain rail joint local size, and increase chain rail saves bears more heavily stressed adaptability to changes.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of prior art;
Fig. 3 be in prior art fixedly guide produce the schematic diagram of friction with driving the engagement of gear teeth piece;
Fig. 4 is that in the utility model, the rolling guide produces the schematic diagram of friction with driving the engagement of gear teeth piece.
Wherein, 1, bearing pin; 2, the outer hole of chain rail joint; 3, chain rail joint endoporus; 4, rolling guide; 5, fixing guide; 6, seal ring A; 7, seal ring B; 8, end plug; 9, oil pocket; 10, oilhole.
The specific embodiment
Illustrate the utility model below in conjunction with accompanying drawing.
Referring to Fig. 1 and Fig. 4, the utility model comprises a plurality of chain rail joints, between adjacent chain rail joint, by bearing pin 1, with guide, be connected, described bearing pin 1 inserts in the endoporus of described guide, described guide comprises fixedly guide 5 and rolling guide 4, and rolling guide 4 is arranged between chain rail joint endoporus 3, and fixedly guide 5 is arranged at chain rail joint endoporus interior 3, rolling guide 4, fixedly between guide 5 and chain rail joint endoporus 3, seal ring A6 is set, fixedly guide 5 and chain rail save between outer hole 2 seal ring B7 are set; Rolling guide 4 and bearing pin 1 free-running fit.Be provided with oil pocket 9 in bearing pin 1, bearing pin 1 sidewall is provided with oilhole 10, and oil pocket 9 outer ends are provided with end plug 8.
Claims (2)
1. a bulldozer rolling lubrication crawler belt, comprise a plurality of chain rail joints, between adjacent chain rail joint, by bearing pin, with guide, be connected, described bearing pin inserts in the endoporus of described guide, it is characterized in that, described guide comprises fixedly guide and rolling guide, the roller bolt cover is arranged between chain rail joint endoporus, the set pin cover is arranged in chain rail joint endoporus, and the rolling guide, fixedly guide saves between endoporus seal ring A is set with the chain rail, and fixedly guide and chain rail save between outer hole seal ring B is set; Rolling guide and bearing pin free-running fit.
