Abstract
The utility model relates to a torque motor with a hollow shaft. A main shaft of the torque motor is a hollow shaft, the torque motor further comprises a rotor, a stator, a front end cover, a rear end cover and a machine casing, wherein the front end cover and the rear end cover are fixed with the hollow shaft through a bearing, the machine casing is fixed with the front end cover and the rear end cover through a motor fastening rod, the rotor and the stator are arranged among the front end cover, the rear end cover and the machine casing, and the rotor is fixedly connected with the hollow shaft to form an internal rotor structure. The hollow shaft is used for replacing the solid through-shaft adopted by the ordinary torque motor, so that the weight of the motor is reduced, the hollow shaft allows the workpiece to pass through when the longer workpiece is processed, the direction of the cutter head is not required to be greatly changed to adapt to the position of the workpiece and the influence on length of the workpiece is free; a step type structure is adopted at one end of the hollow shaft and used for installing the cutter head, the operation is very convenient, the torque motor can be taken as a blower when running in a connection with the cutter head, the heat emission speed of the motor is increased and the service life of the motor is prolonged; and the rated rotational speed can reach 3000 rpm and the powder is 0.5-3.0 KW.
Description
Technical field
The utility model is a kind of torque motor, is specially a kind of hollow shaft torque motor.
Background technology
The drive motors of at present a lot of machining industry has all adopted torque motor, because torque motor is with constant force square outputting power, can directly drive, saved belt drive system, improved running precision, and the rotating speed of torque motor can pass through the encoder free adjustment, so the use of torque motor is subjected to increasing welcome.
But general torque motor is because the rotor resistance height, loss is big, the heat that is produced is also big, even more serious when low cruise and stall especially, therefore, except that less 100 seat No. of output torque and following motor, motor generally is equipped with independently axial flow or centrifugal fan on rear end cap, do the forced ventilation cooling.
The main shaft of existing torque motor all is a solid shafting, the cutterhead that processing work is used is installed in an end of solid shafting, owing to be solid shafting, want that the overall weight that alleviates torque motor just is restricted, when processing long workpiece simultaneously, the putting position of workpiece is restricted, and often needs to increase intermediate gearing to change hand of cutter significantly, position between cutterhead and the workpiece is met the requirements, and usually putting of workpiece and cutterhead is very difficult.
Summary of the invention
The technical problems to be solved in the utility model is: the ventilation cooling problem that the torque motor that existing machine work is used exists, the weight of existing torque motor reduces and is restricted simultaneously, complicated operation difficulty during the long workpiece of processing length.
The technical solution of the utility model is: the hollow shaft torque motor, the main shaft of torque motor is a hollow shaft, also comprise rotor, stator, front end housing, rear end cap and casing, front and rear cover is fixed by bearing and hollow shaft, casing is fixed by motor anchorage bar and front and rear cover, rotor and stator are arranged between front and rear cover and casing, and rotor is fixedlyed connected with hollow shaft, constitute inner rotor core.
The utility model hollow shaft outside also is provided with lining, and described lining is positioned at by the rotor.Lining can be used as the support of air-cored axis, makes hollow shaft need not other structure setting and strengthens rigidity, as the part of main shaft, plays the effect of damping, has made full use of the space in the motor simultaneously, makes internal structure of motor compact more.
As further improvement, the utility model air-cored axis one end is provided with staircase structural model, is convenient to the installation of cutterhead.
Main shaft of the present utility model adopts hollow shaft structure, the solid axis that replaces the employing of general force torque motor with air-cored axis, thereby reduced the weight of motor device, one end of hollow shaft is installed the cutterhead that processing work is used, when the long workpiece of processing, during as the external screw thread of cutting long size work, air-cored axis can allow workpiece pass through, do not need to change the position that hand of cutter adapts to workpiece significantly, compare original solid shafting torque motor, be not subjected to the effect length of workpiece; Hollow shaft one end connects cutterhead, is equivalent to air blast during running, has accelerated motor radiating, has prolonged motor useful life; The utility model rated speed can reach 3000rpm, power 0.5～3.0Kw, and when being applied in the machine work, hollow shaft one end adopts staircase structural model, is used for installing cutterhead, and is very convenient.
Description of drawings
Fig. 1 is the utility model structure chart.
Embodiment
As Fig. 1, the hollow shaft torque motor, the main shaft of torque motor is a hollow shaft 1, also comprise rotor 2, stator 3, front end housing 4, rear end cap 5 and casing 6, front and rear cover 4,5 is fixing with hollow shaft 1 by bearing 7, and casing 6 is fixing with front and rear cover 4,5 by motor anchorage bar 8, and rotor 2 and stator 3 are arranged on 6 of front and rear cover 4,5 and casings, rotor 2 is fixedlyed connected with hollow shaft 1, constitutes inner rotor core.One end of hollow shaft 1 is provided with staircase structural model 10, is used to the cutterhead that processing work is used is installed, and is very convenient.
The utility model hollow shaft 1 outside also is provided with lining 9, and described lining position 9 is other in rotor 2.Lining 9 can be used as the support of air-cored axis 1, makes hollow shaft 1 need not other structure setting and strengthens rigidity, as the part of main shaft, plays the effect of damping, has made full use of the space in the motor simultaneously, makes internal structure of motor compact more.
Main shaft of the present utility model adopts hollow shaft structure, the solid axis that replaces the employing of general force torque motor with air-cored axis, thereby reduced the weight of motor device, when processing long workpiece, as when cutting the external screw thread of long size work, air-cored axis can allow workpiece pass through, and does not need to change significantly the position that hand of cutter adapts to workpiece, compare original solid shafting torque motor, be not subjected to the effect length of workpiece; Hollow shaft one end connects cutterhead, is equivalent to air blast during running, has accelerated motor radiating, has prolonged motor useful life; When the utility model was applied in the machine work, hollow shaft one end adopts staircase structural model, is used for installing cutterhead, and was very convenient.
