Abstract
The utility model provides a shoe pin type odontoid chain which comprises an inner side chain piece and an outer chain piece, wherein the inner side chain piece and the outer chain piece are hinged through a pin shaft; the shoe pin type odontoid chain is characterized in that the end surface outline of the pin shaft is formed by combining two circular arcs with different radii in a rounding-off way and is shaped like a tile; the shape of a chain hole of the inner side chain piece is the same with the end surface outline of the pin shaft; the outline of a chain hole of the outer side chain piece adopts an envoloping line trajectory formed by rotating the end surface outline of the pin shaft to a certain angle and is crescent-shaped; and the pin shaft is fixed in the chain hole of the inner side chain piece. The utility model has the advantages of simple structure, good wear-resisting property and the like, thereby being favorable for mass production.
Description
Technical field
The utility model relates to a kind of silent chain.
Background technique
Silent chain is to be staggered by some groups of tooth shape chain board, is coupled to each other with hinge to form.Carrier bar both sides working surface is a straight flange, and angle is 60 °, leans on the engagement of carrier bar working surface and sprocket teeth to realize transmission.The hinging manner of existing silent chain mainly contains three kinds, and a kind of is round pin formula silent chain (seeing accompanying drawing 1), and second kind is bearing shell formula silent chain (seeing accompanying drawing 2), and the third is roller type silent chain (seeing accompanying drawing 3).In these three kinds of hinge patterns, round pin formula abrasion resistance properties is relatively poor, and bearing shell formula and roller type abrasion resistance properties are better, but the manufacturing process complexity is difficult to produce in enormous quantities.
The model utility content
The purpose of this utility model just provides a kind of better than round pin formula silent chain abrasion resistance properties, and is simpler than bearing shell formula and roller type silent chain structure again, and watt pin formula silent chain that can conveniently produce in enormous quantities.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of watt of pin formula silent chain, side chain sheet and outer side chain sheet in comprising, hinged between interior side chain sheet and the outer side chain sheet by bearing pin, the end profile that it is characterized in that bearing pin is to be combined through rounding off by two different circular arcs of radius, the profile of the similar tile of shape, the profile phase of the shape in the chain hole of side chain sheet and pin roll end face together in described, the profile in the chain hole of described outer side chain sheet forms the envelope track for the pin roll end face profile rotates to an angle, shape is just like crescent moon, and bearing pin is fixed in the chain hole of interior side chain sheet.When entering into sprocket wheel, chain cooperates, arc surface on arc surface on the bearing pin and the outer side chain sheet takes place to roll and cooperates, when chain withdrawed from the cooperating of sprocket wheel, the cooperation of the arc surface on arc surface on the bearing pin and the outer side chain sheet was returned to linear state with means of rolling again.
The utlity model has simple in structurely, characteristics such as abrasion resistance properties is good are convenient to produce in enormous quantities.
