Abstract
The invention provides a coupling which mainly adopts a housing and a coupling sleeve to convey torque by a zigzag spring embedded into the housing. The coupling mainly has the advantages of good damping effect, long service life, start security, high efficiency, low noise, reliable running, good lubrication performance, simple structure, convenient assembly and disassembly, high reliability, light weight, small size and simple manufacture technological process, and also has the advantages that the varying load bearing range is large, a big installation deviation and a certain deviation of a rotor are allowed, and good adaptability is achieved during axis deflection due to high flexibility.
Description
Technical field
The present invention relates to a kind of shaft coupling.
Background technology
Shaft coupling is primarily used to couple the driving shaft in different institutions and driven shaft, so as to rotate the mechanical part transmitting moment of torsion together, is the important component part of machine driven system.Shaft coupling is widely applied in fields such as universal machine, metallurgical equipment, chemical machinery, aviation, boats and ships, electronic equipments.
Dividing according to whether have elastic performance, shaft coupling pattern mainly has positive coupling and yielding coupling.Positive coupling is also called fixed rigid coupling, and it has the advantages of: simple in construction, easy to manufacture, and maintenance cost is relatively low；Do not cushioned and damping effect by ten, therefore it is required that the axis centering coupling two axles to be got well, be mainly used in the occasion of underloading, friction impact.Yielding coupling is generally divided into again two classes, namely fast coupling, flexible member yielding coupling.The former only has the ability compensating two axle relative displacements, and the latter not only has compensation performance and also has buffer shock-absorbing effect, therefore starts diverse high speed shaft frequent, positive and negative many selections the latter.The present invention provides a kind of flexible member yielding coupling.
Summary of the invention
For solving above-mentioned technical problem, the invention provides a kind of shaft coupling, it uses Serpentis spring as flexible member, and increase oil-way whole shaft coupling is lubricated, make shaft coupling have intensity height, transmission moment of torsion ability is big, life-span length, be unlikely to deteriorate, stable performance, the advantage that physical dimension is little.
A kind of shaft coupling, it includes case, described case is tubular structure, it is provided with sealing ring in described case, described sealing ring is connected to inside case, described case inner seal ring be arranged below Serpentis spring, described Serpentis spring be arranged below lubrication groove, described lubrication groove can pass into lubricating oil for the lubrication to whole shaft coupling internal part, described lubrication groove be arranged below coupling sleeve.
Preferably, described case is formed by aluminum material casting.
Preferably, described Serpentis spring is made up of manganese alloy spring steel.
Preferably, described Serpentis spring is made up of 60Si2Mn silicomangan spring steel.
A kind of shaft coupling provided by the invention, it has the beneficial effects that: shaft coupling is mainly by case, coupling sleeve, moment of torsion is transmitted by embedding the Serpentis spring in cover body, its advantage mainly has: good damping result, life-span is long, bear fluctuating load scope bigger, clean boot, efficiency is high, noise is low, reliable, lubricate, simple structure, easy disassembly, allow bigger installation deviation, rotor is allowed to have certain deviation, well adapting to property when being caused journal offset by ten sufficient flexibilities, high reliability, light weight, overall dimensions is little, simple process for making；When withstanding shocks with live load, there is tensionally elastic Serpentis spring and can bear varying load, absorb buckles, reduce vibration；Use silicomangan spring steel steel as the material of Serpentis spring simultaneously, there is high yield strength, spring steel has good elasticity, plastic deformation is not easily caused when bearing heavy load, there is higher fatigue strength, there is long service life under load repeated action, and have enough toughness, can effectively prevent unexpected brittle failure under impact force action；Cover body adopts aluminum material to make, and lightweight, shock resistance is good；Arranging oil-way in cover body, being connected with lubricating oil in this groove itself can be lubricated coupling sleeve and Serpentis trouble, it is ensured that work efficiency and safety.
Accompanying drawing explanation

Accompanying drawing 1 is the structural representation of the present invention.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described.
The present embodiment as it is shown in figure 1,
A kind of shaft coupling, it includes case 1, described case 1 is tubular structure, it is provided with sealing ring 2 in described case 1, described sealing ring 2 is connected to inside case 1, described case 1 inner seal ring 2 be arranged below Serpentis spring 4, described Serpentis spring 4 be arranged below lubrication groove 3, described lubrication groove 3 can pass into lubricating oil for the lubrication to whole shaft coupling internal part, described lubrication groove 3 be arranged below coupling sleeve 5, described case 1 is formed by aluminum material casting, and described Serpentis spring is made up of 60Si2Mn silicomangan spring steel.
A kind of shaft coupling provided by the invention, shaft coupling is mainly by case, coupling sleeve, transmitting moment of torsion by embedding the Serpentis spring in cover body, its advantage mainly has: good damping result, life-span length, bear fluctuating load scope compared with big, clean boot, efficiency is high, noise is low, reliable, lubricate, simple structure, easy disassembly, permission have certain deviation compared with big installation deviation, permission rotor, caused journal offset by ten sufficient flexibilities time well adapting to property, high reliability, light weight, overall dimensions process for making little, simple；When withstanding shocks with live load, there is tensionally elastic Serpentis spring and can bear varying load, absorb buckles, reduce vibration；Use silicomangan spring steel steel as the material of Serpentis spring simultaneously, there is high yield strength.Spring steel has good elasticity, not easily causes plastic deformation when bearing heavy load, has higher fatigue strength, has long service life, and have enough toughness under load repeated action, can effectively prevent unexpected brittle failure under impact force action；Cover body adopts aluminum material to make, and lightweight, shock resistance is good.
The described above of disclosed embodiment of this invention, makes professional and technical personnel in the field be capable of or uses the present invention.The multiple amendment of these embodiments be will be apparent from for those skilled in the art, and generic principles defined herein can without departing from the spirit or scope of the present invention, realize in other embodiments.Therefore, the present invention is not intended to be limited to the embodiments shown herein, and is to fit to the widest scope consistent with principles disclosed herein and features of novelty.
