Abstract
The present invention relates to a kind of T-shaped bond structure, comprise T-shaped key body, described T-shaped key body growth strip structure, on described T-shaped key body, interval has multiple bolt hole, and the boss place of described T-shaped key body is provided with lubricating process groove; The both sides being positioned at T-shaped key body upper part projection have lubrication groove, and described lubrication groove extends to lubricating process groove.The present invention is rational in infrastructure, easy to make, by distinguishing processing and lubrication groove in T-shaped key body upper part projection both sides, reach good lubrication effect, avoid lubrication effect difference in prior art and cause there is rubbish card defect on the contact surface, improve connection reliability, extend the working life of T-shaped key, reduce costs.
Description
Technical field
The present invention relates to expanding equipment technical field, especially a kind of T-shaped bond structure for installing expanding cone and voussoir connection work.
Background technique
At present, in expanding equipment, T-shaped key is the parts that in expanding equipment, cone and voussoir inclined-plane are slidably connected, in prior art, T-shaped key is general T type structure, only play the effect of cone and voussoir connected element, unlubricated function, lubrication effect is poor, easily the impurity cards such as rubbish are had on the contact surface in assembly process, affect the connection work of cone and voussoir, shorten the working life of T-shaped key, cost is high.
Summary of the invention
The applicant is for the shortcoming in above-mentioned existing production technology, and provide a kind of T-shaped bond structure rational in infrastructure, thus make its high lubricating effect, improve the working life of T-shaped key, functional reliability is good, and cost is low.
The technical solution adopted in the present invention is as follows:
A kind of T-shaped bond structure, comprise T-shaped key body, described T-shaped key body growth strip structure, on described T-shaped key body, interval has multiple bolt hole, and the boss place of described T-shaped key body is provided with lubricating process groove; The both sides being positioned at T-shaped key body upper part projection have lubrication groove, and described lubrication groove extends to lubricating process groove.
Further improvement as technique scheme:
Be positioned at T-shaped key body one end and have auxiliary hole;
Described lubrication lubricating process groove becomes arc structure;
Described T-shaped key body adopts copper product;
Described T-shaped key body adopts the beryllium copper of copper alloy material.
Beneficial effect of the present invention is as follows:
The present invention is rational in infrastructure, easy to make, by distinguishing processing and lubrication groove in T-shaped key body upper part projection both sides, reach good lubrication effect, avoid lubrication effect difference in prior art and cause there is rubbish card defect on the contact surface, improve connection reliability, extend the working life of T-shaped key, reduce costs.
The present invention adopts beryllium copper material, and have high wear resistance, good lubricating properties, long service life, cost is low.

Wherein: 1, auxiliary hole; 2, bolt hole; 3, T-shaped key body; 4, lubrication groove; 5, lubricating process groove.
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
As shown in Figure 1, Figure 2, Figure 3 and Figure 4, the T-shaped bond structure of the present embodiment, comprises T-shaped key body 3, and T-shaped key body 3 is grown up strip structure, and on T-shaped key body 3, interval has multiple bolt hole 2, and the boss place of T-shaped key body 3 is provided with lubricating process groove 5; The both sides being positioned at T-shaped key body 3 top projection have lubrication groove 4, and lubrication groove 4 extends to lubricating process groove 5.
Be positioned at T-shaped key body 3 one end and have auxiliary hole 1.
Lubrication lubricating process groove 5 one-tenth arc structures.
T-shaped key body 3 adopts copper product.
T-shaped key body 3 adopts the beryllium copper of copper alloy material.Itself have good lubricating and wear-resisting, and oil absorption is good, heat conduction amount is fast, and high temperature resistant, various intensity also meets T-shaped key job requirement.
Adopt the T-shaped key of tin bronze, actual use 3000 ~ 5000 steel pipes just wear and tear later and have scrapped, and adopt the actual usage quantity of T-shaped key of beryllium copper to reach 20000 ~ 50000 steel pipes, long service life.
The present invention adopts beryllium copper, reducing cone directly contacts the friction of formation characteristic with T-shaped key, by being strict with T-shaped key own dimensions, it being connected with voussoir and cone, ensure the gap value on cone surface and voussoir inclined-plane.In addition, T-shaped key body 3 adds lubrication groove 4, has reached lubrication effect, avoided in prior art and have the impurity such as rubbish and be stuck in contact surface, improve connection reliability, increase the service life.
More than describing is explanation of the invention, and be not the restriction to invention, limited range of the present invention, see claim, within protection scope of the present invention, can do any type of amendment.
