Abstract
The utility model discloses a coupling transmission device. The coupling transmission device comprises a driving transmission shaft and a driven transmission shaft, wherein an upper connector is arranged at the right end of the driving transmission shaft, a lower connector is arranged at the left end of the driven transmission shaft, and the upper connector is matched with the lower connector; and a coupling sleeve is fixed on the exterior of the upper connector and the lower connector, cross sections of the upper connector and the lower connector are both formed by minor arcs and straight edges in an enclosing mode, and a wedge block is arranged between the upper connector and the lower connector. Preferably, an inner flattening screw is arranged on the coupling sleeve and matched with the wedge block. The coupling transmission device has the advantages that the device can overcome the defects of severe abrasion of a connecting head brought by the negative factors that load of transmission shafts are enlarged, the speed is quickened, torque change is irregular, and the like.
Description
Technical field
The present invention relates to technical field of transmission, especially relate to a kind of coupling transmission device.
Background technique
The moment of torsion transmission mostly is the driven by motor initiative drive shaft in the roller way kiln, and initiative drive shaft drives passive transmission shaft.General, the moment of torsion transmission between initiative drive shaft and the passive transmission shaft has 2 kinds of modes.That is: 1), semicircle shaft coupling transmission.See illustrated in figures 1 and 2ly, initiative drive shaft 10 right-hand members are provided with upper connection 11, passive transmission shaft 20 left ends are provided with lower contact 21.This upper connection 11 and lower contact 21 match.That is, the equal semicircular in shape of cross section of upper connection 11 and lower contact 21, and upper connection 11 and lower contact 21 external stabilities have coupling band 30.2), flat key shaft coupling transmission.See Fig. 3 and shown in Figure 4, the left end of the right-hand member of initiative drive shaft 10 and passive transmission shaft 20 is relative is positioned at coupling 30, and initiative drive shaft 10 and passive transmission shaft 20 are provided with connecting key.These 2 kinds of modes are simple and practical, are widely used.
But along with furnace output increases, the kiln inner width increases thereupon, and transmission speed is more and more faster.Simultaneously, the factors such as driven loads increase, the irregular variation of moment of torsion all can't be satisfied the demand the transmission of semicircle shaft coupling or the transmission of flat key shaft coupling, and it is serious to embody a concentrated reflection of contact surface abrasion.Especially (have a power failure empty kiln, transmission clockwise and anticlockwise) during the improper production of kiln, air-flow in the kiln, temperature variation is larger, and the roller rod is very easily crooked, at this moment the load several times that skyrocket, and the torsion of whole transmission all transmits by the transmission shaft coupling band, then the contact surface abrasion of transmission shaft is more very.Trace it to its cause for: exist the gap larger between axle and the axle, when the irregular variation of load and when strengthening, this gap can continue to strengthen.And coupling band only relies on screw terminal point to contact fixation method with face, when screw terminal is subject to the axle radial force, also can becomes flexible and comes off.Like this, the lighter, connecting key wearing and tearing or semicircle connecting head torsional deformation cause transmission speed to change, and walk the brick out-of-flatness; Severe one, connecting key rounding or semicircle connecting head twist off, and driving shaft moment passes less than driven axle, causes the stifled kiln of folded brick, even disconnected rod, has a strong impact on production safety.
Summary of the invention
Deficiency for above-mentioned prior art exists the purpose of this invention is to provide a kind of coupling transmission device, and it has the less characteristics of transmission shaft contact surface abrasion.
To achieve these goals, the technical solution adopted in the present invention is: coupling transmission device, comprise initiative drive shaft and passive transmission shaft, wherein, the initiative drive shaft right-hand member is provided with upper connection, passive transmission shaft left end is provided with lower contact, and this upper connection and lower contact match, and upper connection and lower contact external stability have coupling band, the cross section of described upper connection and lower contact surrounds by minor arc and straight flange, and is provided with wedge-shaped blocks between upper connection and the lower contact.
Described coupling band is provided with interior flat screw, and flat screw and wedge-shaped blocks match in this.
After adopting said structure, the present invention is compared with existing technology the advantage that has and is: the transmission shaft contact surface abrasion is less.The cross section of the initiative drive shaft of coupling transmission device of the present invention and the connecting head of passive transmission shaft (comprising upper connection and lower contact) is comprised of minor arc and straight flange.Like this, after a side of the surface of contact of upper connection and lower contact contacts, form wedge shape between the surface of contact of upper connection and lower contact.At this moment, be provided with wedge-shaped blocks between upper connection and the lower contact, make between the surface of contact and fit fully.Like this, the active area of transmitting torque strengthens, and has avoided the situation of upper connection and lower contact local pressure, can overcome the impact of the connecting head serious wear that the unfavorable factors such as transmission shaft load increase, speed are accelerated, change in torque is irregular bring.

Embodiment
The following stated only is preferred embodiment of the present invention, does not therefore limit protection scope of the present invention.
Embodiment, see Fig. 5 and shown in Figure 6: coupling transmission device comprises initiative drive shaft 10 and passive transmission shaft 20.Certainly, initiative drive shaft 10 is connected to motor.Wherein, initiative drive shaft 10 right-hand members are provided with upper connection 11, passive transmission shaft 20 left ends are provided with lower contact 21, and this upper connection 11 and lower contact 21 match, and upper connection 11 and lower contact 21 external stabilities have coupling band 30.That is, upper connection 11 and lower contact 21 stop mutually in that coupling band 30 is interior, thereby can transmitting torque.Simultaneously, the cross section of this upper connection 11 and lower contact 21 surrounds by minor arc and straight flange, and is provided with wedge-shaped blocks 40 between upper connection 11 and the lower contact 21.Like this, greatly reduced the gap between the surface of contact of upper connection 11 and lower contact 21, make this coupling transmission device can overcome the unfavorable factor impacts such as transmission shaft load increase, speed are accelerated, change in torque is irregular, thereby contact surface abrasion has been less.
Optimize, coupling band 30 is provided with interior flat screw 31, and flat screw 31 and wedge-shaped blocks 40 match in this.That is, this flat screw 31 holds out against wedge-shaped blocks 40.Like this, it is comparatively simple to make this coupling transmission device change accessory.That is: unscrew interior flat screw 31, with wedge type block 40 top pines, unclamp the fixedly retaining screw of coupling band 30, at last coupling band 30 being struck from the installation position is replaceable part of damage.
