Abstract
The utility model belongs to the technical field of transmission equipment, relates to chains, in particular to a large-pitch garage chain, and solves the technical problems that the prior art is low in reasonableness. The large-pitch garage chain comprises a plurality of chain links connected in sequence. Each chain link comprises a pin. Two ends of each pin are provided with outer chain plates. The inner side of each outer chain plate is provided with an inner chain plate. Each pin is sleeved with a sleeve. A roll locating between two inner chain plates is sleeved outside each sleeve. The large-pitch garage chain is characterized in that two ends of each roll are provided with bearings between the corresponding sleeve and the roll. Compared with the prior art, the large-pitch garage chain has the advantages that the chain is especially applicable to garage chains and high in bearing capacity and longer in service life; the large-pitch garage chain is fine in chain synchronism, stable in transmission and low in transmission noise; the large-pitch garage chain is well durable and widely applicable to fields.
Description
Technical field
The utility model belongs to the transmission device technical field, relates to chain, especially relates to a kind of coarse pitch garage chain.
Background technique
Chain is a kind of multi-purpose machinery basic part that consists of flexible system rigid member, is mainly used in meeting the functional requirements such as transmission, conveying, towing.Wherein, roller chain is a kind of widely used chain type, and it mainly is comprised of elements such as outer plate, interior, bearing pin, sleeve and rollers.Existing chain bearing capacity is poor, and noise rings in transmission, noise not only causes very big interference to people's normal life and work, affect people's talk, thinking, affect people's sleep, make the people produce agitation, slow in reacting, working efficiency reduces, take sb's mind off sth, cause operating irregularity, more serious noise can make people's hearing and health suffer damage.
For example, Chinese patent literature discloses a kind of chain [application number: CN200820213364.8], comprise most have respectively the outer link unit of one first outer chain sheet, most inner link unit that there is respectively one first inner chain sheet, and in order to inside and outside link units serial connection is to the chain pin of one.At least one the first inner chain sheet have one with the heterochromatic coating layer of one of the first outer chain sheet outer surface that joins.At least one chain pin have one be coated on its to one of should the first outer chain sheet on end face and with the homochromy painting chromatograph of the coating layer of the first inner chain sheet.
Although such scheme has transmission preferably, still exist noise louder, people's normal life and work are caused to very big interference, affect people's talk, thinking, affect people's sleep.
Summary of the invention
The purpose of this utility model is for the problems referred to above, provides a kind of reasonable in design, simple in structure, and transmission is good, the coarse pitch garage chain that noise is little.
For achieving the above object, the utility model has adopted following technical proposal: this coarse pitch garage chain, comprise some connected chain links successively, described chain link comprises bearing pin, at the two ends of bearing pin, is respectively equipped with outer plate, in the inboard of every outer plate, is respectively equipped with inner plate, on bearing pin, cover has sleeve, in the sleeve outer race, the roller between two inner plates is arranged, it is characterized in that, described roller two ends are respectively equipped with the bearing between sleeve and roller.
In above-mentioned coarse pitch garage chain, described roller inboard has bulge loop, and two bearings lay respectively at the both sides of bulge loop.
In above-mentioned coarse pitch garage chain, the two ends of described outer plate be respectively equipped with for bearing pin through and by stamping forming outer plate hole.
In above-mentioned coarse pitch garage chain, the two ends of described inner plate be respectively equipped with for bearing pin through and by stamping forming inner plate hole.
In above-mentioned coarse pitch garage chain, the aperture light bright band in described outer plate hole and inner plate hole >=80%.
In above-mentioned coarse pitch garage chain, an end of described bearing pin is provided with the convex shoulder coordinated with one of them outer plate, and the other end is arranged with the protruding cover coordinated with another outer plate.
In above-mentioned coarse pitch garage chain, the end that described bearing pin is provided with protruding cover is provided with nuts and washers.
Compared with prior art, the advantage of this coarse pitch garage chain is: 1, be specially adapted to use as the garage chain, bearing capacity is strong, increases the service life.2, the chain synchronism is good, and transmission is stable, and in transmission, noise is little.3, serviceability is good, and suitable application area is extensive.
