Abstract

The utility model discloses a rolling pin type chain, which is mainly characterized in that the rolling pin is also arranged besides a chain plate. Two inner chain plates 1 on an inner chain segment are arranged on both ends of an inner rolling pin 2 and are fixedly connected. Two outer chain plates 3 on an outer chain segment are arranged on both ends of an outer rolling pin 4 and are fixedly connected. The inner and the outer chain segments are connected by a higher pair which is composed of the two rolling pins 2 and 4 on the inner and the outer chain segments.

Description

Roll pin formula chain

The utility model relates to a kind of General Mechanical Parts---chain.

Chain divides two big classes, common roller chain and silent chain.There is following shortcoming in common roller chain: 1. polygon effect causes impacting and noise.2. be sliding friction between sleeve and the bearing pin, after both abrasions, the pitch elongation, and show as pitch and do not wait, around to sprocket wheel, becoming " inequilateral polygonal ", increase the transverse vibration of chain speed fluctuation and chain, tooth takes place when serious to jump, the ability to work of chain is limited by wear extent, and bulk strength can not be given full play to.3. structure more complicated, it is made up of five parts: sleeve connects firmly inner plate together, constitute inner link, bearing pin connects firmly outer plate together, constitute outer link, form sliding pair by sleeve and bearing pin more inside and outside chain link is linked, and add a roller, be subjected to the wearing and tearing of sprocket tooth to alleviate sleeve at the sleeve skin.

The purpose of this utility model is to eliminate the above-mentioned shortcoming of common roller chain, provides a kind of chain with " rolling friction " and " switching political loyalty apart from performance ".

For achieving the above object, the utility model is except that being provided with carrier bar, also be provided with and roll pin, roll pin 2 two ends in two inner plates 1 are arranged on the inner link and connect firmly, two outer plates 3 are arranged on and outer roll pin 4 two ends and connect firmly on the outer link, by two rolling the higher pair that

2 and 4 forms inside and outside chain link is linked on the inside and outside chain link.

The utility model is because inside and outside link design becomes rolling friction to connect, and polygon effect and wear extent reduce, so skin needn't add roller again, thereby simplify the structure.Therefore not only simple in structure, and easy from heavy and light, technology, higher pair connects the particular design of form and carrier bar shape, makes that the chain buffer capacity is strong, and fretting wear is little, running steadily, noise is low, is difficult for producing slippage phenomenon, long service life.Particularly suitable is at many dust, in the farm machinery of many silt particles and the transmission and feedway on the mining machinery, can also be used in the occasion that some should not apply oiling agent, little as weaving, food machinery and ask for something vibration, in the low various mechanical transmissions that run up of noise, thereby being expected future becomes the Updated product of common roller chain.

Accompanying drawing 1 is the utility model plan view.

Accompanying drawing 2 is the utility model plan views.

Accompanying drawing 3 is the utility model carrier bar plan views.

Accompanying drawing 4 is the utility model carrier bar sectional views.

Accompanying drawing 5 is that the utility model rolls the pin plan view.

Accompanying drawing 6 is that the utility model rolls the pin sectional view.

The utility model can further be implemented by following scheme:

Referring to accompanying drawing 1, Fig. 2, chain is made of the inside and outside chain link of more piece, and chain link comprises carrier bar.Roll pin 2 two ends in two inner plates 1 are arranged on the inner link and connect firmly, two outer plates 3 are arranged on and roll pin 4 two ends and connect firmly outward on the outer link, by two rolling the higher pair that

Referring to accompanying drawing 3, accompanying drawing 4, inner plate 1, outer plate 3 shapes can be the same, the thickness unanimity, and the carrier bar inboard connects into many arcuate sockets by the multistage arc, adopts punch die once to be washed into.

Referring to accompanying drawing 5, accompanying drawing 6, roll pin 4 on the outer link and roll pin, roll pin 2 on the inner link and be the short pin that rolls, long pin 4 and the outer plate 3 of rolling for long, short pin 3 and inner plate 1 drive fit of rolling, fitting surface is the cylndrical surface, except that fitting surface, rolls the Cylindrical object of the operative body of

2 and 4 for multi sphere face composition, Cylindrical object as four cambered surfaces composition, can adopt drawing-die, drawing, and through cutting off, turning two terminal circle cylinder forms.
