Description
Technical Field
The invention relates to the field of mechanical transmission, in particular to a quick assembly and disassembly axial expansion compensation structure based on a diaphragm coupler.
Background
In a mechanical transmission system, various couplings are widely adopted to realize connection from a power source to a working machine, so that errors in equipment installation alignment, machining precision and the like can be eliminated, vibration is reduced, and the aim of long-term, safe and stable operation of mechanical equipment is fulfilled. Among the many couplings, crowned couplings are used in a relatively wide variety of applications. The device not only has the capability of compensating the centering and the angle, but also has the function of axial expansion compensation. The disadvantage is the need to periodically replenish grease; the working environment temperature is between-20 ℃ and 80 ℃, namely the highest working environment temperature is lower; the seal is susceptible to aging, etc. In the case of environments of workplaces, which are bad, high in temperature, or quick assembly, disassembly and replacement of a connected gear box and a working machine, the crown gear coupling is obviously insufficient in structure, and a novel coupling and a connecting structure are needed to replace the crown gear coupling.
At present, the diaphragm coupling, also called a laminated flexible coupling, is gradually and widely applied in various industries due to the advantages of lubrication free, high temperature resistance, strong environmental applicability and the like. The working environment temperature is between-20 ℃ and 250 ℃. However, since the axial expansion compensation function is not provided, the axial expansion compensation device cannot be widely used in some places, particularly places where quick assembly and disassembly are required or the structure is compact. If a structure can be developed, the diaphragm coupler also has an axial expansion compensation function, namely, the diaphragm coupler has the advantages of a crowned tooth coupler and the characteristics of the diaphragm coupler, and the use field and the use function of the diaphragm coupler are greatly widened.
Disclosure of Invention
According to the technical problem that the diaphragm coupler does not have the axial expansion compensation function, the quick assembly and disassembly axial expansion compensation structure based on the diaphragm coupler is provided.
The invention adopts the following technical means:
quick loading and unloading axial telescopic compensation structure based on diaphragm shaft coupling, including diaphragm shaft coupling, its characterized in that: the diaphragm coupler is characterized by further comprising a transition flange and a working machine flange which are sequentially arranged along the axis of the diaphragm coupler, wherein the transition flange is provided with a connecting column fixedly connected with a flange hole at the driven end of the diaphragm coupler, a compensation ring I and a compensation ring II are sequentially arranged between the transition flange and the working machine flange, and the compensation ring I and the compensation ring II are clamped between the transition flange and the working machine flange through connecting bolts.
The compensation ring I comprises two semi-rings I, the compensation ring II comprises two semi-rings II, and the split structure is adopted, so that the compensation ring I and the compensation ring II are convenient to radially install and take out.
The transition flange is provided with a positioning spigot in clearance fit with the outer circle of the compensation ring I, the working machine flange is provided with a positioning protrusion in clearance fit with the inner circle of the compensation ring I, and the length of the positioning spigot along the axial direction of the diaphragm coupler is smaller than the thickness of the compensation ring II (so as to ensure that the compensation ring I can completely withdraw from the positioning spigot). The outer circle of the compensation ring I is matched with the positioning spigot, the inner circle of the compensation ring I is matched with the positioning protrusion, then the compensation ring II is inserted between the compensation ring I and the working machine flange, penetrates through the connecting bolt and is screwed. Due to the positioning of the inner circle and the outer circle of the compensation ring I, the coaxiality of the working machine flange and the driven end flange of the diaphragm coupler is ensured. When the working machine or the tested gearbox (the gearbox test bed is tested, and the next gearbox is replaced immediately, such as a gearbox for mass production, a wind power speed increaser and the like), the connecting bolts are loosened, the compensation ring II is pulled out, and the compensation ring I is moved out of the positioning spigot right and is pulled out radially.
The outer circle of the compensation ring I is matched with the positioning spigot in an H7/g6 mode, and the inner circle of the compensation ring I is matched with the positioning protrusion in an H7/g6 mode.
The axial distance between the transition flange and the flange of the working machine is the axial expansion amount of the quick assembly and disassembly axial expansion compensation structure based on the diaphragm coupler, the axial expansion amount can be increased or decreased by changing the thickness of the compensation ring I according to the requirement, and meanwhile, the axial expansion amount can ensure smooth lifting of the working machine.
The invention has the following advantages:
1. the diaphragm coupler does not need to be disassembled, so that the working accuracy is improved and the service life is prolonged.
2. The working efficiency of replacing the working machine or the tested gearbox is improved.
3. The use function and application range of the diaphragm coupler are expanded, and even the crowned tooth coupler is replaced.
For the reasons, the invention can be widely popularized in the fields of mechanical transmission and the like.
