Abstract

The utility model discloses an adjusting driving device used for the seeding tank and the fermenter in pharmaceutical industry, which can also be used in chemical industry, food industry, etc., comprising a belt driving device which is driven by electrical machine and is arranged on the support frame. The support frame is arranged on the speed reducer through a bearing and a connecting plate; the drive main shaft is supported in the shaft sleeve with a bearing; a pair of belt pulleys are respectively arranged on the drive main shaft and the motor shaft. The utility model can meet the requirement of the adjustable speed of renewing pharmacon kinds, having easy replacement and short construction period, and can obviously reduce the labour intensity of the constructor.

Description

Adjustable speed transmission gear for pharmaceutic production

Seeding tank, fermenting tub speed-regulating actuator that the utility model provides a kind of pharmaceutical industry to use.It also can be used for chemical industry, food service industry.

At present, be widely used in the seeding tank on the pharmaceutical industry manufacturing mechanism or the revolution of fermenting tub, after the medicine typing is produced, fix.Produce new pharmacopoeia if change, the revolution of used seeding tank or fermenting tub will be according to the requirement change of production technology.Traditional practice is that the speed reducer on the jar is dismantled, and changes original pulley gear and carries out speed governing.Therefore the workload of Plant reconstruction plant modernization is big, long construction period, and influence is produced, and this has become the main difficult problem that need solve when pharmaceutical industry is transformed manufacturing mechanism.

The purpose of this utility model provides a kind of improved seeding tank, fermenting tub speed-regulating actuator, and it can not only satisfy the speed governing requirement of changing new pharmacopoeia, and changes easily, and short construction period can reduce labor intensity.

The purpose of this utility model is achieved in that this device is by being assembled on the support and utilizing motor-driven belt drive unit to constitute.Its medium-height trestle is packed on the speed reducer by axle sleeve and joining plate, and the transmission main shaft that installs with the input end of speed reducer utilizes bearing to be bearing in the axle sleeve, and a pair of belt pulley is assembled in respectively on transmission main shaft and the motor shaft.When changing the rotating speed that new pharmacopoeia need change jar, as long as take off motor on the existing equipment speed reducer, change the utility model, and its main shaft is packed in the speed reducer input end can uses.

Because the utility model adopts overall structure, speed reducer integral body that will original equipment is pulled down, and only need pull down the motor of speed reducer input end, the transmission main shaft that installs this device then can use, so change easily, obviously shorten construction period, alleviate workmen's labor intensity greatly.If in the time of need changing the rotating speed of jar in addition once more, as long as change the requirement that the speed ratio of belt pulley just can satisfy rotation speed change rapidly.Therefore, when improving Utilization ratio, also can reduce the expense of equipment rehabilitation.

Below in conjunction with accompanying drawing the utility model is further described.

Fig. 1 is a kind of concrete structure schematic representation of the utility model.

Fig. 2 is the sectional view of Fig. 1 along the A-A line.

Describe concrete structure of the present utility model in detail according to Fig. 1-3.1 belt pulley, 2 motors are adjusted plate, 3 belts, 4 belt pulleys, 5 joining plates, 6 axle sleeves, 7 transmission main shafts, 8 supports, 9 supporting sleeves, 10 motors among the figure.This device is an integrated mechanism.Its belt drive unit is the belt pulley 1 and 4 by a pair of different-diameter, and belt 3 formations.Belt pulley 1 is packed on the axle of motor 10, and belt pulley 4 utilizes supporting sleeve 9 to be packed on the transmission main shaft 7.The other end of transmission main shaft 7 is packed in the input end of speed reducer, and utilizes bearing to be bearing in the axle sleeve 6.Motor 10 is assembled on the support 8, and adjusts the tightness that plate 2 is adjusted belt pulley 1 and 4 belts 3 of belt pulley by motor.Support 8 is packed on the speed reducer by axle sleeve 6 and joining plate 5.The installation of this appliance stand 8 and the replacing of belt pulley are very easy to, so that it can solve effectively is that industries such as present pharmaceutical industry or chemical industry, food exist, by the manufacturing technique requirent reforming equipment, carry out the problem of speed governing, particularly the desirable speed-regulating actuator of pharmaceutical industry seeding tank or fermenting tub.

Claims

1, a kind of pharmaceutical purpose speed-regulating actuator, comprise by motor-driven belt drive unit, it is characterized in that the support in the device is packed on the speed reducer by axle sleeve and joining plate, the transmission main shaft that installs with the input end of speed reducer utilizes bearing to be bearing in the axle sleeve, and a pair of belt pulley is assembled in respectively on transmission main shaft and the motor shaft.
