Abstract
The utility model relates to a transfer mechanism, in particular to a conveying chain, which comprises an inner chain plate, an outer chain plate, a shaft sleeve, a shaft pin and a sleeve barrel, wherein the outer chain plate is provided with a counter bore, the shaft sleeve is sheathed in the counter bore, and the outer chain plate and the shaft sleeve are in built-in type connection. The conveying chain is characterized in that the counter bore is arranged on the outer chain plate so that the outer chain plate and the shaft sleeve are in built-in connection, so the friction between the shaft sleeve and other components is reduced, the durability of the shaft sleeve is enhanced, and the dustproof and waterproof effects can be preferably realized.
Description
Technical field
The utility model relates to a kind of transport sector, is specifically related to a kind of conveyer chain.
Background technology
The pin link plate of present existing conveyer chain all is that external is connected with axle sleeve, and so not only axle sleeve easily is worn, and the dustproof and waterproof effect is not good yet.
The utility model content
The purpose of this utility model provides a kind of simple in structure, and parts are few, wear-resistant and conveyer chain that the dustproof and waterproof effect is good.
Above-mentioned technical purpose of the present utility model is achieved by the following technical programs:
A kind of conveyer chain, comprise inner plate, pin link plate, axle sleeve, bearing pin and sleeve, described inner plate and pin link plate link together by axle sleeve, bearing pin and sleeve, described jacket casing is located at outside the bearing pin, described axle sleeve is set in bearing pin two, described pin link plate is provided with counterbore, and described axle sleeve is sheathed in the counterbore, and described pin link plate is built-in with axle sleeve and is connected.The utility model is offered counterbore on pin link plate, make pin link plate and axle sleeve be built-in and be connected, and has so not only reduced the friction of axle sleeve and miscellaneous part, has increased the durability of axle sleeve, more can better play the effect of dustproof and waterproof.
As preferably, sleeve is a cylindrical shape.Sleeve does not adopt flat gesture structure, not only can reduce processing capacity, and sleeve and inner plate area of contact are increased, and the magnitude of interference is bigger, increases the service life.
As preferably, bush material is used 35CrMo instead by 40Cr, and alloying element is more in the material, and shearing strength value is stronger, thereby increases the service life.
In sum, the utlity model has following beneficial effect:
1, the utility model is offered counterbore on pin link plate, makes pin link plate and axle sleeve be built-in and is connected, and has so not only reduced the friction of axle sleeve and miscellaneous part, has increased the durability of axle sleeve, more can better play the effect of dustproof and waterproof;
2, the utility model sleeve does not adopt flat gesture structure, not only can reduce processing capacity, and sleeve and inner plate area of contact are increased, and the magnitude of interference is bigger, increases the service life.

Fig. 1 is a lateral plan of the present utility model;
Fig. 2 is a top plan view of the present utility model;
Wherein 1 is inner plate, the 2nd, and pin link plate, the 3rd, sleeve, the 4th, axle sleeve, the 5th, bearing pin.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
This specific embodiment only is to explanation of the present utility model; it is not to restriction of the present utility model; those skilled in the art can make the modification that does not have creative contribution to present embodiment as required after reading this specification sheets, but as long as all are subjected to the protection of patent law in claim scope of the present utility model.
Embodiment 1: a kind of conveyer chain, comprise inner plate 1, pin link plate 2, axle sleeve 4, bearing pin 5 and sleeve 3, inner plate 1 links together by axle sleeve 4, bearing pin 5 and sleeve 3 with pin link plate 2, described sleeve 3 is sheathed on outside the bearing pin 5, described axle sleeve 4 is set in bearing pin 5 two, described pin link plate 2 is provided with counterbore, and described axle sleeve 4 is sheathed in the counterbore, and described pin link plate 2 is built-in with axle sleeve 4 and is connected.
Claims (2)
1. conveyer chain, comprise inner plate, pin link plate, axle sleeve, bearing pin and sleeve, described inner plate and pin link plate link together by axle sleeve, bearing pin and sleeve, described jacket casing is located at outside the bearing pin, described axle sleeve is set in bearing pin two, it is characterized in that: described pin link plate is provided with counterbore, and described axle sleeve is sheathed in the counterbore, and described pin link plate is built-in with axle sleeve and is connected.
