The utility model relates to a mechanical transmission device with a detachable shaft coupling piece, which is characterized in that the utility model is provided with a detachable shaft coupling piece. The utility model comprises an opening conical sleeve 1, a fastening screw 4 and a conical pin 6, wherein the fastening screw 4 and the conical pin 6 are arranged between a rotary wheel 5 and a shaft 3, a key 2 is embedded in the surface of the shaft 3, and the opening conical sleeve 1 is sheathed on the shaft 3. The conical surface of the opening conical sleeve is matched with the inner hole surface of the rotary wheel 5, and the matching surface is provided with the conical pin 6 used for positioning and the fastening screw 4 used for fixing. The structure is suitable for the connection of a belt pulley, the shaft and the key, and the installation position of the coupling piece can be axially adjusted. The utility model has the advantages of convenient assembly and disassembly and small space for assembling operation and disassembling operation. The utility model is particularly suitable for the occasions where an apparatus transmission device occupies small space and needs to be assembled and disassembled frequently.

Description

Mechanical transmission device with removable shaft coupling piece
The utility model belongs to a kind of mechanical transmission that the removable shaft coupling is arranged, and the belt drive unit of removable shaft coupling is particularly arranged.
Roulette wheel in the present mechanical transmission, for example belt pulley, Vee pulley V, sprocket wheel, cam, gear etc. directly connect with axle, use the key transmitting torque, and axle adopts interference fit with roulette wheel.Shown in Figure 4 is a kind of typical connecting mode, and roulette wheel among the figure (5) is a belt pulley, directly connects with axle (3), and interference fit is with key (2) transmitting torque.This connection needs the pressure assembling, need use special extracting tool during dismounting, and needs certain operating space, mounting or dismounting inconvenience.For the limited occasion in operating space, inconvenient especially.
At above problem, the utility model provides a kind of mechanical transmission that the removable shaft coupling is arranged, and the axle coupling of easy mounting or dismounting is arranged between roulette wheel and axle, and modern design connects reliably, can solve the problem of above-mentioned existence.
The utility model is finished with following mode: the axle coupling that will easily install and remove is installed between roulette wheel and the axle.Be embedded with key on the axle surface, this coupling comprises opening tapered sleeve, fastening screw trip bolt and taper pin, and the opening tapered sleeve is sleeved on the axle, and its tapering surface cooperates with the inner hole surface of roulette wheel, is useful on the taper pin of location and the fastening screw trip bolt that is used for fixing on its fitting surface; The opening tapered sleeve opening radially arranged, outer surface is taper, internal surface is cylindric and has the keyway that cooperates with key, and on the outer surface of the big end of opening tapered sleeve interior threaded hole and taper pin-hole is arranged; The inner hole surface of roulette wheel also is the tapering surface that matches with the opening tapered sleeve, and same interior threaded hole and taper pin-hole corresponding to interior threaded hole, taper pin-hole on the big end outer surface of opening tapered sleeve are arranged on the inner hole surface of its big end.On the outer surface of this big end of mechanical transmission opening tapered sleeve that the removable shaft coupling arranged with the taper inner hole surface of roulette wheel on corresponding interior threaded hole can be 2, corresponding taper pin-hole can be 1, and each corresponding interior threaded hole and taper pin-hole all are equal semicircle respectively.The best tapering of its opening tapered sleeve outer surface is 1:8.
Employing comprise an axle coupling that opening tapered sleeve, fastening screw trip bolt and taper pin are formed be installed in the mechanical transmission roulette wheel with spool between after, roulette wheel, comprising that belt pulley, Vee pulley V, sprocket wheel, cam, gear etc. cooperate with the connection of axle changes conical surface locking into by a present wheel and an axle interference fit and cooperates, and the shaft shoulder is located and changed locking and positioning into; Modern design connects reliable; Can transmit identical moment of torsion; Axial adjustment can be done in the coupling mounting point; Mounting or dismounting are convenient, and the mounting or dismounting work efficiency improves more than 2 times, and mounting or dismounting operation requisite space is little, are particularly suitable for equipment and make the transmission device very little occasion often installed and removed of needing again that takes up space.
Now in conjunction with the accompanying drawings the utility model is described in further detail.
Fig. 1 is the structural representation that the removable shaft coupling connects in belt drive unit:
Fig. 2 is opening tapered sleeve (a 1) structural representation;
Fig. 3 is roulette wheel of the present utility model (3), the i.e. structural representation of belt pulley;
Fig. 4 is present prior art middle belt pulley and the connecting structure schematic representation of axle, key.
With reference to Fig. 1, Fig. 2, Fig. 3, this coupling comprises opening tapered sleeve (1), fastening screw trip bolt (4) and taper pin (6).The tapering of opening tapered sleeve (1) is 1:8.During assembling, earlier key (2) is embedded in the keyway of axle (3), the keyway alignment keys (2) that will put roulette wheel (5) more and be the opening tapered sleeve (1) of belt pulley pushes the location, then 2 interior threaded holes on the big end inner hole surface of belt pulley, 1 taper pin-hole and opening tapered sleeve (1) are held 2 interior threaded holes on the outer surface, 1 taper pin-hole aligned position respectively greatly, make each corresponding interior threaded hole and taper pin-hole synthetic circular by semicircle, strain along the conical surface, squeeze into taper pin (6), fastening screw trip bolt (4) is screwed in and screws.Like this, opening tapered sleeve (1) is locked on the axle (3).Moment of torsion between axle (3) and opening tapered sleeve (1) is transmitted by key (2), and roulette wheel (5) is that the moment of torsion of belt pulley and opening tapered sleeve (1) is transmitted by fastening screw trip bolt (4) and taper pin (6).During dismounting, screwing out fastening screw trip bolt (4) earlier, is that belt pulley knocks to small end gently along the conical surface with roulette wheel (5), takes out taper pin (6), unclamps opening tapered sleeve (1), unloads from axle (3) together with belt pulley, opening tapered sleeve (1) etc. then.Install and remove very convenient.Can by shown in Figure 1 with opening tapered sleeve (1) K to assembling, also can be with the anti-K of opening tapered sleeve (1) to assembling.This removable shaft coupling is particularly suitable for belt pulley and axle connects, and the axle that also is suitable for roulette wheels such as mechanical transmission intermediate cam belt pulley, sprocket wheel, cam, gear is with connecting.
