Abstract
A kind of board-like bearing pin chain, comprises bearing pin 1, carrier bar 2 and pin 3, it is characterized in that, have pin sleeve 4 at bearing pin 1 outer side wall cover, and pin sleeve 4 and bearing pin 1 are excessively coordinate, and the internal diameter of pin sleeve 4 is compared with the large 0.1 ~ 0.3mm of the external diameter of bearing pin 1.Bearing pin with the level is changed into the bearing pin of band axle sleeve by the utility model, when the carrier bar of removable parts wearing and tearing and bearing pin, only pin need be taken off, and damages bearing pin and namely can be convenient for changing.
Description
Technical field
The utility model belongs to a kind of kind of drive, specifically for producing and keep the general measures of machinery or effective operation of apparatus.
background technique
At present, beam-and-rail factory of NeiMenggu BaoGang GangLian Co., Ltd uses board-like bearing pin chain on furnace door lifting device, and the bearing pin of this chain is fixed carrier bar by the step of self and the pin of both sides.Because this chain and chain-plate is that front and back superposition links together, when a certain section of chain wear, when wanting to change separately, dismantle time-consuming expense.
Summary of the invention
the purpose of this utility model is to provide oneconvenient when the carrier bar of removable parts wearing and tearing and bearing pin, extend a kind of board-like bearing pin chain in working life of whole chain.
The purpose of this utility model realizes by with under type:
A kind of board-like bearing pin chain, comprises bearing pin 1, carrier bar 2 and pin 3, it is characterized in that, have pin sleeve 4 at bearing pin 1 outer side wall cover, and pin sleeve 4 and bearing pin 1 are excessively coordinate, and the internal diameter of pin sleeve 4 is compared with the large 0.1 ~ 0.3mm of the external diameter of bearing pin 1.
beneficial effect:the beneficial effects of the utility model are, bearing pin with the level are changed into the bearing pin of band axle sleeve, when the carrier bar of removable parts wearing and tearing and bearing pin, only pin need be taken off, and damage bearing pin and namely can be convenient for changing.
accompanying drawing explanation
Fig. 1 is the board-like bearing pin chain structural representation used at present;
Fig. 2 is the structural representation of bearing pin in the board-like bearing pin chain used at present;
Fig. 3 is the board-like bearing pin chain structural representation of the utility model;
Fig. 4 is the structural representation of bearing pin in the board-like bearing pin chain of the utility model;
Wherein: 1-bearing pin, 2-carrier bar, 3-pin, 4-axle sleeve.
Embodiment
embodiment 1
A kind of board-like bearing pin chain, comprises bearing pin 1, carrier bar 2 and pin 3, it is characterized in that, have pin sleeve 4 at bearing pin 1 outer side wall cover, and pin sleeve 4 and bearing pin 1 are excessively coordinate, and the internal diameter of pin sleeve 4 is compared with the large 0.1 ~ 0.3mm of the external diameter of bearing pin 1.
Step before the utility model bearing pin chain eliminates on bearing pin, change the structure of band pin sleeve into, bearing pin both sides pin is fixed.Only need to open pin during dismounting and can take off bearing pin and carrier bar.
