Abstract
The utility model discloses a pin connection device of a vacuum pump coupler. The pin connection device comprises a pin shaft, the two ends of the pin shaft are provided with threads, the middle of the pin shaft is sleeved with a rubber elastic ring, and the two sides of the rubber elastic ring are respectively provided with a fixing gasket and a fixing nut in sequence. According to the pin connection device, the middle of the pin shaft is sleeved with the rubber elastic ring, and the two sides of the rubber elastic ring are respectively provided with the fixing gasket and the fixing nut in sequence, so that the radial deviation, the axial deviation and the angular deviation generated by two shafts in the transmission process can be compensated through the rubber elastic ring, and vibration and noise of the device during operation can be reduced. The pin connection device further has the advantages of being large in transmitted torque, convenient to maintain and disassemble, high in abrasive resistance, long in service life, simple in structure and easy to achieve.
Description
Technical field
The utility model relates to a kind of coupling arrangement, relates in particular to a kind of vacuum pump coupling pin coupling arrangement.
Background technique
Coupling is a kind of general machinery equipment motor and the middleware that bearing or diaxon are connected, and two axles (driving shaft and driven shaft) that are used for connecting in different institutions make it common rotation with the mechanical parts of transmitting torque.In tobacco manufacturing enterprise, often to use vacuum pump.At present, the coupling that tobacco manufacturing enterprise intermediate pump is used connects by plastics pin rod, during use, cylindrical plastics pin rod is contained in to the connection that realizes two half-couplings in two half-coupling shrinkage pools.
In routine work process, the plastics pin rod of existing vacuum pump coupling is due to the long-time working state in shearing and pushing, there will be the situations such as concentricity departs from, angle deviation, cause the rod milling of plastics pin to damage loosening or fracture, the vibration while causing unit operation and noise increase.Meanwhile, plastics pin rod connects, dismounting all bothers very much, is easy to make the distortion of cast iron coupling or damages in maintenance with when changing motor coupler, and increase enterprise cost of production, reduces enterprises production efficiency.
Model utility content
The purpose of this utility model is to provide a kind of vacuum pump coupling pin coupling arrangement, can compensate that diaxon in transmission process produces radially, axially and angle deviation, vibration and noise while reducing unit operation, be convenient to motor coupler to keep in repair and change simultaneously, reduce enterprise's cost of production, improve enterprises production efficiency.
The utility model adopts following technical proposals:
A vacuum pump coupling pin coupling arrangement, comprises that two ends arrange threaded axis pin of column, and axis pin of column middle cover is provided with rubber elasticity circle, and rubber elasticity circle both sides are disposed with retaining washer and set screw nut.
Described set screw nut outside is also provided with stopping shim and locking nut.
Described axis pin of column diameter is 18mm, and length is 190mm.
Described axis pin of column two ends reach is 45mm.
Described set screw nut and locking nut adopt M16 nut.
Described axis pin of column middle cover is provided with 10 rubber elasticity circles.
Described rubber elasticity circle thickness is 10mm, and model is 18*36.
The utility model is sheathed rubber elasticity circle in the middle of axis pin of column, rubber elasticity circle both sides are disposed with retaining washer and set screw nut, can utilize in rubber elasticity circle compensation transmission process that diaxon produces radially, axially and angle deviation, vibration and noise while reducing equipment operation, also have that transmitting torque is large, repair demolition is convenient, wear resistance is strong, the advantage of long service life, simple in structure, is easy to realize.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, the utility model comprises that two ends arrange threaded axis pin of column 1, and axis pin of column 1 diameter is 18mm, and length is 190mm, and axis pin of column 1 two ends reach is 45mm.Axis pin of column 1 middle cover is provided with 10 rubber elasticity circles 22, and rubber elasticity circle 2 thickness are 10mm, and model is 18*36.Rubber elasticity circle 2 both sides are disposed with retaining washer 3, set screw nut 4, stopping shim 5 and locking nut 6, and set screw nut 4 and locking nut 6 adopt M16 nut.
During use, first retaining washer 3 and set screw nut 4 compressed, to realize spacing to 10 rubber elasticity circles 2.While connecting coupling, 10 rubber elasticity circles 2 are arranged in two half-coupling shrinkage pools, and have stopping shim 5 in set screw nut 4 arranged outside, and fixing with locking nut 6.The utility model component part is few, easily manufactured, with low cost.In use, rubber elasticity circle 2 can compensate that diaxon in transmission process produces radially, axially and angle deviation, vibration and noise while reducing equipment operation, also extended to 2 months by original 1 month working life, guaranteed equipment operating efficiency, also have that transmitting torque is large simultaneously, repair demolition is convenient, the advantage that wear resistance is strong.
