Abstract
The utility model discloses a directly connected keyless shaft coupler, which consists of a shaft sleeve, a taper sleeve, a bolt, a compression ring and a pull ring installed at the end of a motor shaft. A step is arranged in an inner hole of the compression ring; and a conical is formed inside the pull ring and matched with the outer wall of the taper sleeve. An external step and an internal blind hole are arranged at the end part of the shaft sleeve; the inner diameter of the blind hole is larger than the outer diameter of the end of the motor shaft; and the conical hole in the opening of the hole is matched with the outer wall of the taper sleeve. The shaft sleeve is a coaxial bidirectional equivalent external taper pipe of which the middle part has larger diameter and the two ends have smaller diameter; an axial open groove is formed on the outer wall; the inner hole has clearance fit with the end of the motor shaft; the taper sleeve which is directly installed at the end of the motor shaft is between the shaft sleeve and the pull ring; and the bolt is connected with the pull ring by passing through the compression ring so as to form a taper incuneation fastening structure. By adopting taper fit connection, the directly connected keyless shaft coupler has high location precision, reliable connection and high torque transmission capability, moreover, the directly connected keyless shaft coupler is easy to assemble and disassemble, and particularly suitable for being matched with a water pump for a ship.
Description
Technical field
The utility model relates to a kind of coupling, and specifically, the utility model relates to and a kind ofly is prone to adorn readily removable straight connection type and do not have the binding axial organ.
Background technique
Coupling is to use driving component always, is mainly used in the connection diaxon and makes it common revolution and transmit the commentaries on classics distance.Standard equipment such as the water pump that uses in the engineering, blower fan generally use coupling connect supporting power equipment.The commodity coupling of supplying on the market all passes through key and connects with the axle head of corollary equipment no matter be rigid joint or resilient connection in its structure.The quality of fit decision transmission quality of coupling and supporting axle head in order to improve installation quality, is chosen as micro-interference fit with coupling and cooperating of supporting axle head usually.Interference fit just assembling accordingly or dismounting process complications, for example heating press-fits coupling needs supporting corresponding heating plant and press-loading device, the coupling that press-fits afterwards during device maintenance the dismounting difficulty big, have in addition to do destructive dismounting.Generally speaking, although the coupling of existing technology is simple in structure, it is reliable to connect, the mounting or dismounting technology difficulty is big.Boats and ships are mobile big and the mounting point is narrow, require corollary equipment to be prone to adorn readily removable, and the coupling of existing technology is a key connection structure, and it is supporting to be not suitable for shipborne equipment, and it is supporting particularly to be not suitable for water pump peculiar to vessel.
The model utility content
The utility model is primarily aimed at existing technology and is not suitable for the supporting problem of water pump peculiar to vessel, propose a kind of simple in structure, connect reliable, be prone to adorn readily removable straight connection type and do not have the binding axial organ.
The utility model is realized technical goal through following technical proposals.
Straight connection type does not have the binding axial organ, and it is made up of the axle sleeve, tapered sleeve, bolt, pressure ring and the draw ring that are installed on the motor shaft end.Said pressure ring and draw ring are the flange-like member, on the same circumference of end face, are uniformly distributed with axial hole, and the endoporus at pressure ring middle part is provided with step, and the endoporus at draw ring middle part is that conical bore cooperates with the reverse equivalent tapering outer wall of tapered sleeve.Its improvements are: said axle sleeve is the axle head that connects corollary equipment; Boss face is a blind hole structure towards an end of motor shaft end; The blind hole internal diameter is greater than the gas-distributing motor axle head external diameter 2mm～6mm of institute; The aperture conical bore cooperates with the reverse equivalent tapering outer wall of tapered sleeve, and the sleeve end outer wall is provided with the abduction step and cooperates with pressure ring.Said tapered sleeve is the equivalent external taper pipe of coaxial two-direction; Mid diameter is big; The two ends diameter is little, and outer wall is provided with a shaft orientation opening groove, endoporus and motor shaft end Spielpassung; Be directly installed on tapered sleeve on the motor shaft end between axle sleeve and draw ring, bolt passes pressure ring and connects draw ring and constitute tapering wedging locking mechanism.
In the said structure, tapered sleeve two ends tapering outer wall is 1:10～1:15 with the axle sleeve, the draw ring conical bore tapering that match.
The utility model compared with prior art has following good effect:
1, coaxial be nested simple in structure, easy to manufacture;
2, the taper fit connection has self-locking performance, and Location accuracy is high, helps improving installation quality;
3, by the awl wedging structure of bolt locking, connect reliably, transmit and change strong apart from ability;
4, unload bolt, just can withdraw from axle sleeve, draw ring, dismounting very easily, more important is to accomplish nondestructive demounting, practices thrift maintenance cost greatly, it is supporting to be particularly suitable for water pump peculiar to vessel.

Fig. 2 is a tapered sleeve axis projection schematic representation.
Embodiment
According to accompanying drawing and combine embodiment, the utility model is described further below.
Straight connection type shown in Figure 1 does not have the binding axial organ, and it is made up of the axle sleeve 1, tapered sleeve 2, bolt 3, pressure ring 4, the draw ring 5 that are installed on the motor shaft end 6.Said pressure ring 4 is the flange-like member with draw ring 5, on the same circumference of end face, is uniformly distributed with axial hole, and the through hole on draw ring 5 end faces is a screw, and the endoporus at pressure ring 4 middle parts is provided with step, and draw ring 5 middle part endoporus are that conical bore cooperates with tapered sleeve 2 reverse equivalent tapering outer walls.The end that said axle sleeve 1 faces motor shaft end 6 is a blind hole structure, and the blind hole internal diameter is greater than institute's gas-distributing motor axle head 6 external diameter 2mm～6mm, and motor shaft end 6 diameters are got big value greatly, otherwise get the small value.Present embodiment motor shaft end 6 diameters are Φ 20mm, so axle sleeve 1 diameter of bore is than the big 2.5mm of institute's gas-distributing motor axle head 6 external diameters.Axle sleeve 1 aperture conical bore cooperates with tapered sleeve 2 reverse equivalent tapering outer walls, and axle sleeve 1 end outer wall is provided with the abduction step and cooperates with pressure ring 4.Said tapered sleeve 2 is the core component in the utility model, and it is shaped as the equivalent external taper pipe of coaxial two-direction, and mid diameter is big, and the two ends diameter is little, and tapering is 1:12.Tapered sleeve 2 outer walls are provided with a shaft orientation opening groove as shown in Figure 2, and endoporus and motor shaft end 6 Spielpassung are directly installed on tapered sleeve 2 on the motor shaft end 6 between axle sleeve 1 and draw ring 5, and bolt 3 passes pressure ring 4 and connects draw rings 5 and constitute taperings wedging locking mechanisms.The utility model unscrews bolt 3 can do corresponding dismounting, and it is easy to operate, and can not cause damage parts, and the utility model maintenance is easy thus, cost is low, is particularly suitable for water pump peculiar to vessel and cooperates.
