Technology application of reducer

Electric machinery


Characteristic


As a relatively independent part of this product series, there are five varieties and ten series for users to choose. According to varieties: standard motor, speed motor, electromagnetic brake motor, speed electromagnetic brake motor, DC motor. According to the power points: 6W, 15W, 25W, 40W, 60W, 90W, 120W, 140W, 200W, 300W. According to the voltage used, single-phase 110V/220V and three-phase 220V/380V. The motor has independent terminal box to facilitate electrical connection. Because the product line is precision small power machinery, its appearance is exquisite and its size is exquisite. It is strictly forbidden to knock excessively during assembling and using in order to prevent the damage of internal structure. At the same time, attention should be paid to the axial and radial loads of the output shaft in the selection process. In order to ensure the service life, please select the type carefully and use it rationally.

For an independent motor with a circular output shaft, the tolerances of the mounting joint holes of the shaft end parts are 6H7, 8H7, 10H7 and 12H7, respectively, depending on the type. In addition to the design structure, the recommended flexible coupling should be used. It is recommended to use the right angle installation feet of the corresponding specifications when the end face is difficult to install. In addition, when installing the motor with cooling fan, it is advised not to plug the suction outlet at the rear of the motor and to leave no less than 10 mm of space.






Combination of standard gearbox and motor


Characteristic


The motor can be precisely positioned by the end face positioning ring and the standard reducer, which can provide a combination of 1/3~1/200 standard deceleration ratio. For example: speed regulation, electromagnetic brake and other forms.


install


Standard decelerator and motor are precision machinery. The installation process after design and selection is one of the factors that determine the service life.

Connection between motor and standard gearbox


As the assembly of precision machinery, the motor matched with the gearbox has flange port on its connection end. The end face of the gearbox is fitted with the countersink mouth. Users can adjust the gearbox and motor assembly phase according to their own actual situation, that is, can rotate the motor or gearbox according to the illustration. After adjusting to the ideal position, four screws on the fastening flange of the motor. Pay attention to the order of fastening screws, through the diagonal gradually tightening, can make the motor and reducer body close.

Connection with equipment


The connecting surface of the output shaft end of the reducer is a plane, and the connecting hole on it is a threaded hole. The surface is a finely machined plane, which can be directly connected with the machined connecting surface of the equipment. Attention should be given to tightening the way in which the diagonal angle should be gradually tightened. Or the equipment connection is limited, or the design structure difference, recommends the use of special configuration of the right angle installation foot for installation, so that more reliable connection, convenient speed regulation, but also with this matching high-precision flexible coupling for choice.


Similarly, when installing a motor with a cooling fan, be careful not to plug the suction outlet at the rear of the motor. It is recommended that no less than 10 mm of space be left.


The motor, reducer and intermediate reducer of this product series are all tightly geared components, which should be paid special attention when connecting with the load. Strong knocking and wrenching are strictly prohibited. In order to facilitate assembly in the product design career has taken into account such issues, the following is the keyway width of 4mm when the size, shaft diameter tolerance level is h7.

Combination of right angle reducer and motor


Characteristic


Unlike traditional standard gearboxes (or parallel axle gearboxes), in order to provide designers with more choice space, so that the overall equipment is more compact, the company also provides a right angle gearbox transmission form. In addition to all the functions of the standard reducer, the right-angle reducer has a wide range of speed ratio selectivity (i = 3 ~ 600), excellent transmission performance, high strength housing, and compact installation, which is beyond the standard reducer.


Similarly, under the aforementioned conditions, different functional combinations can be realized by selecting different functions of the motor.


For example: speed regulation, electromagnetic brake, reversible and so on.

install


The right angle reducer, intermediate gear box and motor are compact machine guns. The assembly quality after design and selection will directly affect its service life and performance.

Connection between motor and right angle reducer

As the assembling of the compact machine, the motor matched with the right-angle reducer has a flange stop on its connecting end surface besides an independent connecting terminal box. The end face of the right angle reducer is fitted with the countersink port. The user can rotate the relative rotation of the motor and the right angle reduction gear according to the actual situation. After adjustment, four screws are attached to the connecting flange from the firm motor.

Pay attention to the order of fastening screws: gradually tighten diagonally.

Connection with equipment

The end face of the output shaft of the right-angle reducer is a finish machining plane with four through holes distributed on its four corners, which can be directly connected with the machined connection surface of the equipment. The output mode of the right-angle reducer can be divided into two types: the solid shaft and the hollow shaft. Users can choose according to the form of the load, and the bolts should also be fastened. The way of diagonal gradually tightening.

Connection of solid shaft output in right angle reducer


The real shaft output of the right-angle reducer is keyway structure, corresponding to different specifications, and the dimensions of the assembly holes of its output shaft are respectively 12H7, 15H7, 20H7. In connection with load
