Abstract
The invention provides a shoe pin roller chain, which is formed by a plurality of series connection units, each series connection unit comprises two inner chain sheets, two outer chain sheets, a chain shaft which connects the inner and outer chain sheets and a chain roller which is arranged between the two inner chain sheets and can pivot along with the chain shaft. The shoe pin roller chain is characterized in that the chain shaft is formed by a long shoe type shaft pin and a short shoe type shaft pin, one side of the long shoe type shaft pin and the short shoe type shaft pin are circular arc surfaces, the other sides are equipped with grooves, two circular arc surfaces of the two shaft pins are jointed, wherein two ends of the long shoe type shaft pin pass through the grooves to be mutually mesh with an embossment in an inner chain sheet hole, and the height of the short shoe type pin is equal to the distance between the outer lateral faces of the two inner chain sheets. The shoe pin roller chain has the advantages of simple structure, fine wear resistance, long service life and the like.
Description
Technical field:
The present invention relates to a kind of chain.
Background technique:
Chain is the rotating component that a kind of interelement can pivot relatively flexibly, therefore be widely used on the transmission of power of bicycle, locomotive or machinery, existing chain comprises: inner chain sheet, outer chain sheet, wear the chain rivet that the footpath inner chain sheet connects outer chain sheet, the chain that connects the lining of two corresponding inner chain sheets and be installed in the lining outer periphery rolls, this kind chain is when doing the turnover motion, and lining and chain rivet are done and be pivoted relative to each other, and frictional force is big, chain rivet is worn easily, causes the chain rupture phenomenon.
Summary of the invention:
Purpose of the present invention just a kind of chain with wear resistance is provided.
Technological scheme of the present invention: a kind of chain is to be formed by several serial connection cell string, each serial connection unit comprises: two inner chain sheets, two outer chain sheets, connect in each, the chain rivet of outer chain sheet and between between two inner chain sheets, and can roll along the chain that this chain rivet pivots, wherein each inner chain sheet is provided with an opposing side facing to outer chain sheet, each outer chain sheet is provided with an opposing side facing to inner chain sheet, it is characterized in that described chain rivet is by growing watt type bearing pin and lacking two bearing pins of watt type bearing pin and form, one side of described length watt type bearing pin and short watt type bearing pin is an arc surface, opposite side is provided with groove, the arc surface of two bearing pins pastes mutually, the two ends of wherein growing watt type bearing pin are meshing with each other by the convex parts in groove and the outer plate hole, and firmly rivet with outer plate, the two ends of short watt type bearing pin then are meshing with each other by the convex parts in groove and the inner plate hole, between the height of described weak point watt type bearing pin and two inner plates, two outer side surfaces apart from equating.
The present invention has simple in structure, and wear-resisting property is good, characteristics such as long service life.
Description of drawings:
Fig. 1, structural representation of the present invention:
The plan view of Fig. 2, Fig. 1
Embodiment:
Contrast Fig. 1, Fig. 2 as can be known, the present invention is formed by several serial connection cell string, each serial connection unit comprises: two inner chain sheets 1, two outer chain sheets 2, connect in each, the chain rivet 3 of outer chain sheet and between between two inner chain sheets, and can roll 4 along the chain that this chain rivet pivots, wherein each inner chain sheet is provided with an opposing side facing to outer chain sheet, each outer chain sheet is provided with an opposing side facing to inner chain sheet, it is characterized in that described chain rivet 3 is by growing watt type bearing pin 5 and lacking 6 two bearing pins of watt type bearing pin and form, one side of described length watt type bearing pin 5 and short watt type bearing pin 6 is an arc surface 7, opposite side is provided with groove 8, the arc surface of two bearing pins pastes mutually, the two ends of wherein growing watt type bearing pin 5 are meshing with each other by the convex parts 9 in groove and the outer plate hole, and firmly rivet with outer plate, the two ends of short watt type bearing pin 6 then are meshing with each other by the convex parts in groove and the inner plate hole, between the height of described weak point watt type bearing pin and two inner plates, two outer side surfaces apart from equating.
Working principle of the present invention is: during chain operation, when chain when bent state is entered straightened condition (perhaps from) when straightened condition enters bent state, the arc contact surface of two bearing pins is only done a small angle scroll actions, can finish, avoid the chain rivet of conventional chains and the friction between the axle sleeve, thereby improved the wear resistance of chain greatly.
