Abstract
The utility model relates to a roller iron casting machine chain belt with stable drawing, which is used for solving the problem that the method to match an outer chain plate with a long axis is not suitable for large distortion distance transmission. The technical scheme is that: the utility model comprises a link which is composed of an inner chain plate and an outer chain plate, long axes and short axes connecting each link, rollers arranged at two ends of each long axis and a sliding sleeve arranged between the long axes and the rollers; after the utility model is improved, a biplane oblate interference fit is adopted between the outer chain plate and the long axes. The biplane oblate interference fit is adopted between the outer chain plate of the utility model and the long axes and the short axes, which leads to two planes between chain plate holes and the long axes to transfer torque, thus not only increasing the reliability of transmission, but also prolonging the service life of the chain plate and the long axes. In addition, inner sleeves made of friction resistant alloy are added in the roller inner holes, thus converting the badly worn roller inner holes into the inner sleeves and the normal work of the rollers can be restored after the inner sleeves are replaced. The roller iron casting machine chain belt with stable drawing has simple structure, easy realization, and can improve stability of the performance of chain belts and reduce the failure rate of equipment compared with the prior art.
Description
Technical field
The utility model relates to a kind of load transfer device, particularly utilizes the roller chain belt of pig machine of chain-driving transferring iron melt, belongs to the metal casting machine technical field.
Background technology
Pig machine is a metallurgy industry iron-smelter molten iron pourer commonly used.A plurality of chain belt pulling motions that the pig mold of molten iron is housed by circulating motion on the pig machine, the molten iron in the pig mold through the cooling of cooling intallation, is frozen into ingot iron in motion process.Present widely used roller chain belt of pig machine, its main composition partly comprises major axis, minor axis and the roller of pin link plate in chain link, the connecting link, all be provided with a pair roller on the every major axis, in order to the weight that supports pig mold and cooperate chain belt to realize conveying to pig mold, chain belt is the important component part of pig machine.The chain belt of pig machine of conventional structure, adopt the circular hole interference fit method to be connected between its pin link plate and the major axis, this connection mode is done the time spent and is occurred easily cooperating between the axis hole and lost efficacy bearing big twist moment, and then the phenomenon of the relative changing of the relative positions takes place, this phenomenon can influence the stability of pig machine operation on the one hand, cause axle or chain plate hole to damage on the other hand, in addition, it between roller endoporus and the sliding sleeve free-running fit, the roller endoporus not only will bear radial weight and friction of rolling, also to bear certain responsive to axial force, therefore the roller endoporus is a damageable zone, and the wearing and tearing of roller endoporus equally also can influence the stability of pig machine operation.
Summary of the invention
Thereby being used to overcome the defective of prior art, the utility model provides a kind of by changing the stable roller chain belt of pig machine of traction that carrier bar and major axis connection mode improve load-carrying capacity.
The alleged problem of the utility model is that following technical scheme solves:
A kind ofly draw stable roller chain belt of pig machine, comprise the chain link that constitutes by inside and outside carrier bar, the major axis that connects each chain link, minor axis in the formation and be arranged on the roller at every major axis two ends, be provided with sliding sleeve between major axis and the roller, its special feature is: be the oblate interference fit of biplane between described pin link plate and the major axis.
The roller chain belt of pig machine that above-mentioned traction is stable is the oblate interference fit of biplane between described pin link plate and the minor axis.
The roller chain belt of pig machine that above-mentioned traction is stable, described roller is set up interior cover in the hole, interior cover external diameter and roller hole interference fit, interior trepanning and sliding sleeve free-running fit.
The utility model improves at the problem that fitting method between plain cast iron chain band pin link plate and major axis, the minor axis is not suitable for the large torque transmission, changed original fit system, adopt the oblate interference fit of biplane between carrier bar and major axis, the minor axis, make two plane carry-over moments are arranged between chain plate hole and the major axis, both increase the reliability of transmission, prolonged the operating cycles of carrier bar and major axis again.In addition, set up the interior cover of making by abrasion resistant alloy, the roller endoporus of serious wear is converted to interior cover, can recover the normal operation of roller, prolonged the service life of roller by cover in changing at the roller endoporus.The utility model is simple in structure, be easy to realize, compared with prior art improved the stability of chain tape running, reduced equipment failure rate.

The specific embodiment
Referring to Fig. 1, comprise the chain link that constitutes by inner plate 1, pin link plate 3 in the formation of the present utility model, each chain link is connected by major axis 2, minor axis 4, is provided with roller 5 at every major axis two ends.Between pin link plate and major axis and the minor axis for captiveing joint.
Referring to Fig. 1, Fig. 5～7, for improving the reliability of pin link plate and major axis junction carry-over moment, the utility model major axis and pin link plate junction 2-1,2-2 are the flat axle of biplane, and corresponding pin link plate hole is the flat hole of biplane that is complementary with it, and major axis and pin link plate form the oblate interference fit of biplane.This fitting method can effectively improve the reliability and the carry-over moment of chain strap drive.
Referring to Fig. 1, Fig. 2～4, minor axis axle and pin link plate junction 2-1,2-2 also are the flat axle of biplane, and corresponding pin link plate hole is the flat hole of biplane that is complementary with it, and minor axis and pin link plate form the oblate interference fit of biplane.
Still referring to Fig. 1, for reducing the wearing and tearing of roller 5 endoporus, the utility model has been set up an interior cover 6 of being made by abrasion resistant alloy in the roller hole, cover external diameter and roller hole interference fit, interior trepanning and sliding sleeve 7 free-running fits in this.After setting up this interior cover, the wearing and tearing in roller hole can be transferred to interior cover, in only changing after the interior cover wearing and tearing, overlap roller and get final product normal operation.
