Abstract
The utility model relates to a driving device of a drum comprising a direct drive servo motor and a drum body. A motor housing, wherein a motor stator is directly disposed on a supporting base, is also provided in the utility model. A flange is fixedly disposed on one end of the drum body. A drum transmission shaft is fixedly disposed on the center of the flange, and is inserted into an inner chamber of the motor rotor. The drum transmission shaft and the motor rotor are in a tolerance cooperation, and can be fastened together by a fastening part. In the driving device provided in the utility model, a rotatable rigid integral body can be formed by the motor rotor, the transmission shaft, the flange and the drum body, and a stationary integral body can be formed by a motor stator, the supporting base, and an installation wallboard, besides, the reliable two-point support of the rotatable part and the stationary part can be realized by bearings. According to the requirement of the direct drive motor, the precision of the transmission shaft and the supporting base can be guaranteed by the mechanical design, and the high speed stable rotation of the drum directly driven by the motor can be realized.
Description
Technical field
The utility model relates to tobacco machine, and concrete is the drum actuating device in cigarette machine and the filter-stick forming device.
Background technology
On cigarette and filter stick formation equipment; Drum assembly inside is furnished with negative pressure; The part groove position of surface of tub wheel communicates with negative pressure, can adsorb that cigarette props up and filter stick, thereby makes drum transmit when rotating that cigarette props up and filter stick; Can realize the online cutting of being correlated with on this basis, detect and removing function.
Like Fig. 1, drum assembly comprises drum body 9, flange 8, and supporting seat 3, transmission shaft 4, and bearing 5 and 6, it is installed on the wallboard 7 by supporting seat 3.Its conventional drive is designed to: motor 12 drives transmission shaft through engaging gear 11 and 10, and flange 8 is given drum body 9 with transmission of power then, has realized the transmission of power that drum drives.
Traditional drum drives and has disadvantage: 1, motor drives drum through the multi-stage gear engagement, and noise is big, and efficient is low.2, gear mesh is gapped, and wearing and tearing are arranged after the long-time running, the driving error of accumulation on long messenger chain, can occur, causes the transmission synchronization accuracy not high.3, gear transmission must adopt grease lubrication, and machine design is complicated, and maintaining bothers, and has the risk of oil leaking pollution.4, under a drive power source, the number of slots of the modulus of gear 10 and drum body 9 must be consistent, and could realize the synchronized operation of multistage drum.Therefore when changing drum body 9 at the conversion production specification, must be synchronously gear changing 10 more, implement pretty troublesome.
Summary of the invention
In order to overcome the shortcoming of traditional drum wheel drive pattern, the utility model provides a kind of new design of drum direct drive unit.
The utility model solves the technical scheme that its technical matters adopted:
The actuating device of this drum comprises a directly-drive servo motor and drum body, and this motor stator and rotor connect for no bearing; Electric machine casing, promptly motor stator is directly installed on the supporting seat, and an end of drum body is fixed with flange; The center fixation of flange has the drum transmission shaft, it is characterized in that, the drum transmission shaft stretches in the rotor inner chamber; Both pass through tolerance fit, and are locked by fastener.
Assembly &Disassembly becomes department of assembly's cover with motor, transmission shaft, supporting seat and design bearing for ease, the whole Assembly &Disassembly that on wallboard, carries out.
In the actuating device of the utility model; Rotor, transmission shaft, flange and drum body constitute the rigid unitary of a rotation; Motor stator, supporting seat and installation wallboard constitute a static integral body, and rotating element and stationary part are realized 2 supports of failure-free by bearing; According to the requirement of direct driving motor, machine design guarantees the precision of transmission shaft and supporting seat, can realize motor direct-drive drum high-speed smooth rotation simultaneously.
The beneficial effect of the utility model is:
1. the direct rigidity of motor drives drum, and noise is little, and driving efficiency is high.
2. the transmission of power of rigidity does not have the gap error of transmission, add the high precision and the high dynamic response performance of servo driving, so the synchronization accuracy between the drum is very high.
3. cancelled transmission gear and grease lubrication, machine design is simplified with installing, and the maintaining work in the equipment operation reduces, and has eliminated grease and revealed the hidden danger that pollutes.
4. when the conversion production specification, only need to change the drum body, servo driving is according to the parameter that is provided with of drum groove number, can the synchronous speed of automatic compensation, therefore satisfy the quick specification change request of producing.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is described further:
Fig. 1 is the cutaway view of traditional drum wheel drive.
Fig. 2 is the cutaway view of the utility model drum direct drive.
Among the figure: 1. motor stator, 2. rotor, 3. supporting seat, 4. transmission shaft, 5. bearing, 6. bearing is 7. installed wallboard, 8. flange, 9. drum body, 10. gear, 11. gears, 12. motors.
The specific embodiment
In Fig. 2, drum drives the directly-drive servo motor of employing standard, and this motor stator 1 connects with rotor 2 no bearings; With electric machine casing, promptly motor stator 1 is installed on the supporting seat 3, and drum transmission shaft 4 stretches into rotor 2; Both pass through tolerance fit, and are directly locked by tightening screw.
In this type of drive; Rotor 2, transmission shaft 4, flange 8 and drum body 9 constitute the rigid unitary of a rotation; Motor stator 1, supporting seat 3 and installation wallboard 7 constitute a static integral body, and rotating element and stationary part are realized 2 supports of failure-freies by bearing 5 and 6; According to the requirement of direct driving motor, machine design guarantees the precision of transmission shaft 4 and supporting seat 3, can realize motor direct-drive drum high-speed smooth rotation simultaneously.
