Abstract
The utility model provides a wear-resisting transmission component connected through a pin, and belongs to the field of transmission mechanisms. The wear-resisting transmission component connected through the pin comprises a first connecting rod and a second connecting rod which are connected with each other by the pin through connecting rod holes. A cotter pin is arranged on one end portion of the pin through a radial through hole. The wear-resisting transmission component connected through the pin is characterized in that self-lubricating type bushings are arranged in and in interference fit with the connecting rod hole of the first connecting rod, a plurality of radial through holes are formed in the walls of the self-lubricating type bushings, and the pin connects the first connecting rod with the second connecting rod through the self-lubricating type bushings. The wear-resisting transmission component connected through the pin is reasonable in structure, convenient to operate and use, capable of enabling the bushings to contact the pin through modified connecting rod structure so as to reduce the wear from the connecting rods to the pin and enable a special surface treatment for the pin to be unneeded, capable of meeting the requirements of the connecting portion by adoption of common stainless steel materials, and successful in achieving the purpose of good connection and cost reduction.
Description
Technical field:
The utility model relates to a kind of driving mechanism, the wear-resisting transmitting assemblies that especially a kind of pin connects.
Background technique:
In power equipment, some moving element is because the multiple reversal reciprocating motion, long-term friction and cause the wearing and tearing of part.Pin is as an important transmission part, and the processing mode on Material selection and surface is particularly important.At present, when the design power equipment is used pin, for overcoming the prolonged exercise wearing and tearing, can adopt at pin surfaces plating molybdenum disulfide and process, still, because complex process, cost is high, and a lot of enterprises still continue to use traditional machining pin, cause the pin serious wear.
The model utility content:
The wear-resisting transmitting assemblies that the utility model provides a kind of pin to connect to alleviate the wearing and tearing to pin, has solved problems of the prior art, has reached the purpose of good connection and reduction cost.
The utility model is to solve the problems of the technologies described above the technological scheme that adopts to be:
The wear-resisting transmitting assemblies that a kind of pin connects, comprise the first connecting rod and the second connecting rod that are connected by tie rod holes by pin, end at pin is provided with cotter pin by radial direction through hole, it is characterized in that, interference fit is installed a self-lubricating type lining in the tie rod holes of first connecting rod, be provided with a plurality of radial direction through hole in described self-lubricating type jacket wall, described pin links together first connecting rod and second connecting rod by the self-lubricating type lining.
Described self-lubricating type lining is brass bushing.
Described self-lubricating type lining is graphite bushing.
Described self-lubricating type lining is three-decker, and internal layer is the little lubricated top layer of friction factor, and the middle level is layer of brass, and skin is the steel backing base layer.
The utility model adopts such scheme, its beneficial effect is: it is rational in infrastructure, easy for operation, by changing bar linkage structure, lining and pin are contacted, reduce connecting rod to the wearing and tearing of pin, make pin need not carry out special surface treatment, adopt the common stainless steel material just can satisfy the joint requirement, reached the purpose of good connection and reduction cost.
Description of drawings:
Fig. 1 is main TV structure schematic representation of the present utility model;
Fig. 2 is the structural representation of looking up of Fig. 1;
Fig. 3 is self-lubricating type lining master TV structure schematic representation;
Fig. 4 is self-lubricating type lining side structural representation (partial cutaway);
Among the figure, 1, first connecting rod; 2, second connecting rod; 3, pin; 4, packing ring; 5, cotter pin; 6, self-lubricating type lining, 61 radial direction through hole.
Embodiment:
For clearly demonstrating the technical characterstic of this programme, below by embodiment, and in conjunction with its accompanying drawing, the utility model is elaborated.
Such as Fig. 1～shown in Figure 2, the utility model comprises first connecting rod 1, in the attachment hole of first connecting rod 1, connect installing self-lubricating type lining 6 with interference fit, self-lubricating type lining 6 materials are high-tensile strength brass bushing or graphite bushing, be provided with a plurality of radial direction through hole 61 in described self-lubricating type jacket wall, such as Fig. 3-Fig. 4.Opposite side second connecting rod 2 is connected by common stainless steel pin 3, brass washer 4 and the connecting rod 1 that installs self-lubricating type lining 6 additional, and pin 3 ends add cotter pin 5 after connecting, in case shotpin 3 plaies.
Self-lubricating type lining 6 also can be three-decker:
Internal layer is the little lubricated top layer of friction factor, can form the solid lubrication transfer membrane on dual face (round pin surface) during break-in;
The middle level is layer of brass, can with steel backing base layer strong bonded, play the effect of not only wear-resisting but also carrying, conduct simultaneously frictional heat, reduce the temperature of rubbing surface, improve the dimensional stability of rubbing surface;
Skin is the steel backing base layer, usually makes with whole steel bushing, and the steel backing base layer finally plays carrying, heat conduction and assurance lining intensity and dimensional accuracy.
During work, the characteristics such as self-lubricating type lining 6 bearing loads by the steel backing matrix play lubrication by graphite, and this structure has the bearing capacity height, and is shock-resistant, high temperature resistant, and the selflubricating ability is strong.Self-lubricating type lining 6 and pin 3 are contacted, reduce the wearing and tearing of 1 pair of pin 3 of connecting rod.Make pin 3 need not carry out special surface treatment, adopt the common stainless steel material just can satisfy the joint requirement.Greatly reduce the rate of fault of equipment, reduced cost, reduced unnecessary energy loss, improved working efficiency.
The utility model does not describe part in detail, is those skilled in the art of the present technique's known technology.
