An output shaft and a positioning shaft are provided with chainwheels and bearing seats. The utility model has the advantages of compact structure, small size and convenient installation. The utility model is widely suitable for various object conveying systems, such as automatic production lines, turning migration mechanisms, supporting plate type hoisters, etc. The utility model perfectly solves the problems which can not be solved in the power driving devices of the multi-layer production line for a long time.
Description
The utility model relates to the transmission device of automatic production line.
At present, the transmission device on each bar automatic production line, its reduction gearing mechanism generally all are to adopt worm type of reduction gearing, gear reducer, cycloidal-pin wheel retarder, add mechanism's discrete devices such as motor shaft, bearing support, sprocket wheel, belt pulley; The turning mechanism of dividing a word with a hyphen at the end of a line adopts above discrete device too; The support-board type elevator mechanism adopts these devices again equally.So just make production line have complex structure, installation workload is big, and the shortcoming that the volume exclusion position is also big is especially brought many insurmountable contradictions to the multilayer automatic production line.
The purpose of this utility model is to provide a series of motorized pulleys for automatic production line, devices such as motor, reducing gear, sprocket driving are combined into an integral body, simple in structure, volume is little, easy for installation, noise is low, driving torque is big, the life-span also improves greatly.
The utility model is finished as follows: motor, retarder combination coaxial line are installed in the cylindrical shell outside device output shaft, sprocket transmission device, bearing support and the electric source connecting box of cylindrical shell.Motor is a kind of motor special, and its output shaft holds with the one-piece rotor shaft of retarder such as cycloidal-pin wheel retarder and cooperates.Drive one-piece rotor shaft during the motor start-up rotation and hold, make eccentric motion thereby drive cycloidal gear around the motor shaft axis, this is revolution; Simultaneously, form engagement epicyclic transmission mechanism in the tooth difference because the pin tooth of arranging on cycloidal gear and its pin wheel housing is meshed, but around self axis to tooth of revolution direction rotation, rotation that Here it is.At this moment, cycloidal gear is the spinning motion of low speed, cooperated with one group of bearing pin guide on the gear shaft flange by cycloidal gear spoke and one group of equidistant pin-and-hole of arranging.The spinning motion that makes cycloidal gear passes to the gear shaft of plane table thermoconductivity meter by bearing pin, and this just finishes the first order and slows down.The back first class reducer structure such as the plane table thermoconductivity meter of retarder combination, the sun gear gear teeth meshing of planet wheel and gear shaft then, again with housing on internal tooth engagement, the low-speed motion of prime output at this moment passes to planet wheel, force planet wheel to do rotation around self axis, the spider gear shaft axis that detours again revolves round the sun, and by needle bearing and planet wheel shaft the revolution motion of planet wheel is passed to output shaft then, slows down thereby obtain the second level.Because output shaft connects with roller tube, so just make roller also produce the circumference uniform motion of low speed according to the rotating speed of output shaft.
According to the deceleration requirement of different automatic production lines, i.e. the different requirements of drive line speed, then the content of retarder combination is also different: can be slowed down by a cycloidal-pin wheel retarder and the synthetic one-level of motor unit and take action; Also can be by a cycloidal-pin wheel retarder and plane table thermoconductivity meter and motor unit Synthetic 2 level gearing down; Also can be by 2 cycloidal-pin wheel retarders and motor unit Synthetic 2 level gearing down; Can also be with 2 or 2 above cycloidal-pin wheel retarder step planetary gear retarders and the synthetic multi-stage speed-reducing transmission of motor unit.
Because motor field frame, retarder combination housing can not rotate, thereby make fastening connection, and end fitting fan blade at motor, in order to the ventilated machine temperature rise, improve electric motor power, simultaneously the front cover and the also change of rear end cover structure of motor, make it to be fit to the installation of retarder combination and output sprocket, the power lead of motor is taked the positioning shaft structure with axle center hollow, the terminal box of guiding the positioning shaft end into.The power turn-on switch, promptly starting electrical machinery is finished automatic production line deceleration requirement, and can directly place line belt on the cylinder, forms the working surface of automatic production line motion.
Owing in the retarder combination cycloidal-pin wheel retarder is arranged, plane table thermoconductivity meter, thereby make transmission device have that volume is little, in light weight, compact structure; The transmission efficiency height especially adopts one-piece rotor shaft to hold, and bearing capacity is enhanced about more than once, and the radial force of bearing improves 20%; Also avoided the overhang in the conventional transmission device, stressing conditions is improved greatly, life-span and raising greatly; Running is steady, noise free.
