Abstract
The invention belongs to the technical field of mechanical equipment, and particularly relates to a caterpillar track. The caterpillar track adopts the structure that a gap is reserved between a pin bush and a pin roll; an oil storage cavity is formed on the pin roll in the axial direction; at least one cross bore is formed on the pin roll in the radial direction; the cross bore is communicated with the gap and the oil storage cavity; and one end of the oil storage cavity is connected with an oil cup. The caterpillar track has the advantages that lubricating oil is charged into the oil storage cavity through the oil cup, lubricating oil enters the cap between the pin bush and the pin roll through the cross bore, when the pin bush and the pin roll rotate relative to each other, lubricating oil is sufficiently distributed in the gap between the pin bush and the pin roll, proper lubricating effect is realized, the service life of the caterpillar track is effectively prolonged, and the power loss of the interior of the caterpillar track is reduced.
Description
Technical field
The invention belongs to mechanical equipment technical field, relate in particular to a kind of chain rail.
Background technology
Engineering mechanical device is that the chain rail saves and links up as crawler belts used such as bulldozer, excavating machines, wherein between the bearing pin of every joint crawler belt and guide, all there is grease, when caterpillar drive, between bearing pin and guide, relatively rotate, grease plays the effect that reduces friction drag, not only can reduce wearing and tearing, and can reduce the power of crawler belt internal loss.At present; grease is enclosed between bearing pin and guide in the process of crawler belt assembling; can't add grease in the life cycle of crawler belt; because the crawler belt sealing property can not guarantee intact sealing; usually under bad working environments; seal form usually can lose efficacy gradually; what cause thus is that inner grease is slowly revealed and loss; when unlubricated fat; the wearing and tearing meeting of bearing pin and guide inside is very fast; the whole piece crawler belt life-span will terminate rapidly, so the bottleneck in crawler belt life-span often of the undue wear between bearing pin, guide.
Summary of the invention
Given this, the invention provides a kind of chain rail of easy charging-up lubricant oil.
Technical solution of the present invention:
A kind of chain rail, comprise chain rail joint, guide, bearing pin and seal ring, described chain rail is formed through described chain rail joint, described seal ring, described guide, described seal ring and described chain rail joint successively by described bearing pin, leave space between described guide and described bearing pin, described bearing pin axially offers a shoe cream room, described bearing pin radially offers at least one cross-drilled hole, and described cross-drilled hole is communicated with described space and described shoe cream room, and the open end of described shoe cream room is connected with lubricating cup.
Further, the both sides that 2 described cross-drilled hole symmetries the are opened in described shoe cream room cross-drilled hole that partners.
Further, the both sides of described shoe cream room offer 2 pairs of cross-drilled holes.
Further, the both sides of described shoe cream room offer 1 pair of cross-drilled hole.
Further, described lubricating cup and described shoe cream room are fixed in the mode of interference fit.
Beneficial effect of the present invention:
Chain rail of the present invention leaves space between guide and bearing pin, and bearing pin axially offers a shoe cream room, and bearing pin radially offers at least one cross-drilled hole, cross-drilled hole connectivity gap and shoe cream room, and an end of shoe cream room is connected with lubricating cup; Chain rail of the present invention by lubricating cup by oil filling in shoe cream room, lubricating oil enters the space between guide and bearing pin by cross-drilled hole, when guide and bearing pin relatively rotate, lubricating oil fully is covered with the space between guide and bearing pin, play good lubricant effect, effectively extend the service life of chain rail, reduced the watt loss of chain rail inside.
The accompanying drawing explanation
Fig. 1 is the structural representation of one embodiment of the invention;
Fig. 2 is the structural representation of another embodiment of the present invention;
1-chain rail joint, 2-guide, 3-bearing pin, 4-seal ring, 5-space, 6-shoe cream room, 7-cross-drilled hole, 8-lubricating cup.
The specific embodiment
In order to illustrate in greater detail technical scheme of the present invention, below in conjunction with accompanying drawing, the present invention will be further described in detail.
Referring to Fig. 1, a kind of chain rail, comprise chain rail joint 1, guide 2, bearing pin 3 and seal ring 4, described chain rail is formed by the described guide 2 of some described chain rail joint 1 use, described bearing pin 3 and the vertical cross-under of described seal ring 4, leave space 5 between described guide 2 and described bearing pin 3, described bearing pin 3 axially offers a shoe cream room 6, and described bearing pin 3 radially offers 1 cross-drilled hole 7, described cross-drilled hole 7 is communicated with described space 5 and described shoe cream room 6, and an end of described shoe cream room 6 is connected with lubricating cup 8.
Leave space 5 between guide 2 and bearing pin 3, bearing pin 3 axially offers a shoe cream room 6, bearing pin 3 radially offers 1 cross-drilled hole 7, cross-drilled hole 7 connectivity gaps 5 and shoe cream room 6, one end of shoe cream room 6 is connected with lubricating cup 8, by lubricating cup 8, oil filling is arrived in shoe cream room 6, lubricating oil enters the space 5 between guide 2 and bearing pin 3 by cross-drilled hole 7, when guide 2 and bearing pin 3 relatively rotate, lubricating oil fully is covered with the space 5 between guide 2 and bearing pin 3, play good lubricant effect, effectively extended the service life of chain rail, reduced the watt loss of chain rail inside.
In order to allow better lubricating oil enter space 5, can offer in the both sides of shoe cream room 6 a plurality of cross-drilled holes 7, a plurality of cross-drilled holes 7 can symmetrical be opened in the both sides of described shoe cream room 6, the both sides that 2 cross-drilled hole symmetries are opened in shoe cream room 6 cross-drilled hole that partners.In one embodiment, offer 2 pairs of cross-drilled holes in the both sides of shoe cream room 6, as shown in Figure 2.Also can offer in the both sides of shoe cream room 61 pair of cross-drilled hole, take and guarantee that lubricating oil can enter space 5 better as prerequisite.
Lubricating cup 8 is fixed in the mode of interference fit with shoe cream room 6, can lubricating cup 8 is tightly fixing with shoe cream room 6.
To sum up, chain rail of the present invention leaves space between guide and bearing pin, and bearing pin axially offers a shoe cream room, and bearing pin radially offers at least one cross-drilled hole, cross-drilled hole connectivity gap and shoe cream room, and an end of shoe cream room is connected with lubricating cup; Chain rail of the present invention by lubricating cup by oil filling in shoe cream room, lubricating oil enters the space between guide and bearing pin by cross-drilled hole, when guide and bearing pin relatively rotate, lubricating oil fully is covered with the space between guide and bearing pin, play good lubricant effect, effectively extend the service life of chain rail, reduced the watt loss of chain rail inside.
