Abstract

The invention discloses a dual-cross hollow shaft joint, which is applied to carrying out low-speed transmission connection to the shaft and the shaft end with small spacing therebetween in mechanism industry, in particular to connecting shaft ends between an output shaft and a driven shaft of a speed reducer; the transmission performance of the shaft joint is more stable than that of the shaft joints such as sleeve type shaft joint, shaft joint with flange disc and stopping port or elastic round pin shaft joint, claw type elastic rubber cushion shaft joint and the like; the shaft joint disclosed by the invention has no noise, and the parts have long service life; the shaft joint has desirable universal performance in dual-cross connecting; with shaft ends can be closer to each other by the hollow structure, so that the occurred space in the field can be reduced. After putting into practice, the shaft joint has desirable practicability.

Description

The diesis cavity coupling

One, technical field:

Be applied to mechanical industry, axle and the nearer low speed transmission joint of axle head spacing are specially adapted to speed reducer output shaft and connect with axle head between driven axle.

Two, background technique:

The more large-scale electroplating enterprise of Hebei province's Zhuozhou City three ring weaving appliance systems of Co., Ltd at my place, 15 of total plating tanks use 25 of cycloid pin type speed reducers altogether; Speed reducer output shaft all is that straight line docks with driven axle, because gear frame partly is welded structure, and does not have follow-up precision adjustment processing; Therefore be difficult to realize axle with spool between concentric the connection; Adopt case butt coupling and flange plate to add method that seam formula coupling forces to connect with one heart or elastic cylindrical pin coupling and pawl type and add the method that the micro-decentraction of permissions such as elastic rubber fitting coupling connects and all can not deal with problems, have the steady and speed reducer output shaft cutting phenomenon that takes place frequently of transmission, always because of speed reducer output shaft is the core key component; Can not repair; Have only after the damage and buy complete machine again, will use up several ten thousand yuan every year for this reason and buy new machine, for reducing enterprise's waste in this respect; Enterprise has thoroughly solved this respect problem after having adopted newly-designed diesis cavity coupling.

Three, summary of the invention:

Use the diesis cavity coupling to can solve the problem of the nearer and butt joint decentraction of distance between shafts.

This coupling structurally has two characteristics simultaneously: promptly adopting connection of diesis structure and intermediate sizes is cavity structure.

Adopt the diesis structure to connect, can well eliminate axle center uncertainty main, driven axle two side directions, promptly this kind structure has certain universal property, thereby can well be used for non-concentric shafts transmission; And the employing hollow structure, under certain situation, can with lead, the driven axle two ends insert into the inner portion, reduce the coupling occupation space, make the scope of adaptation bigger.

This coupling is compared with the other types coupling and is had the following advantages: stable drive, and noise free, service life of a machine is long, and the axle head spacing is little, occupies little space etc.

My company has promptly accomplished whole transformations from preliminary examination in 2004 success back to 2005, and equipment operation is good, and does not have the speed reducer output shaft of generation cutting phenomenon so far again, makes enterprise solve this respect expenditure above surplus 20 ten thousand yuan.

Four, description of drawings

4.1 being diesis cavity coupling example structure, Fig. 1 always schemes

4.1.1 part code name and technical order

1. main transmission dish; 2. cross land in the middle of; 3. cross in circle; 4. export land; 5. power screw; 6. packing ring; 7. bundle steel wire φ 1.4, L=340; 8. bolt M10 L=20 GB5-76; 9. main drive shaft spindle nose.

4.1.2 transmission process: 9. the power main drive shaft drives the main transmission dish through the key on its axle head cylindrical and 1. rotates, and 5. 2 power screws that part place, maximum outer ring 1. has two prominent pawls to drive on it rotate simultaneously, and 5. part drives cross in circle again and rotate; 2. the cross land rotated in the middle of 5. two other power screw on the cross in circle then drove again; 3. the cross in circle that 5. 2. same cross land drive in it through power screw again rotates; 3. cross in circle then drives the output land and 4. rotates; The seam that 4. the output land is gone up can be connected with driven axle is concentric, and the screw on it can use bolt to be connected with the driven axle flange plate, thereby realizes final output transmission.If output terminal can not connect with flange plate, it is the axle head of minor diameter, and axle head has keyway, then can adopt Fig. 7 type spare to connect transmission.

Five, mode of execution

Zhuozhou City three ring weaving appliance Co., Ltds implement nearly 8 years to this coupling in Hebei province, and are respond well, can carry out in the industry nearly 50 tame enterprises after patent gets the nod in advance, then can be with its seriation and in wider popularization.

Claims

1. the diesis cavity coupling belongs to machine industry axis and the nearer low speed transmission connection of axle head spacing; Single cross structure that this product becomes hinge coupling connects for hollow structure into the entity axle of diesis structure and smaller dimension universal-joint spindle and combines practicality to form, and has overcome case butt coupling and flange plate and has added the transmission that method produced that seam formula coupling forces the method that connects with one heart or adopt elastic cylindrical pin coupling and pawl type to add the micro-decentraction connections of permissions such as elastic rubber fitting coupling and owe steadily, have drawbacks such as noise, part life weak point
