cycloidal speed reducers rapid development of China's domestic reducer to enhance the overall
70 - 80 years, the world reducer skills have been carried out very much, and with the development of new skills closely linked.
Since the reform and opening up, China has introduced a number of advanced processing equipment, after the introduction, digestion, foreign advanced skills and scientific research, and gradually grasp the various types of high-speed and low-speed heavy-duty gear installation design and manufacturing skills. However, most of our slowdown in the skill level is not high, the old product can not be immediately replaced by new and old products coexist transition will experience a longer period of time.
Because of the impact of the global economic crisis, a number of the original main export reducer enterprises have fought in the domestic market, competing for Helical Worm Geared Motors market share, so that competition has been targeted at the domestic market reducer manufacturers brought greater competition and pressure. With China's tax policy and the impact of external economic pressures, some reducer companies began to buy high-end equipment such as grinding machine, and such behavior also opened the screw press drive industry norms.
From the previous gear accuracy of 7 to the accuracy of overdue prelude to imported reducer equipment compared to, can have been comparable with the duration is far shorter than the near-mouth reducer, more competitive.

Reducer is a common power transmission mechanism, in all types of mechanical transmission systems are used

small bevel gearbox is a common power transmission mechanism, in all kinds of mechanical transmission systems are used. Reducer of the device and the use of direct operation related to the reducer results, to fit the skills standards and norms. Reducer reasonable device and use, pay attention to the following points.
1, the hollow shaft gearmotor in the device, we must pay special attention to the middle of the transmission center of the alignment, the error can not be exceeded by the reducer used in the amount of compensation for the coupling. Reducer in accordance with the requirements of the center, you can get more fantastic transmission results and more durable life.
2, the output shaft of the reducer on the device transmission parts, we must pay attention to the operation of the soft, to stop the use of hammer and other things rough device, it is best to use the assembly fixture and the end of the internal thread of the device, Drive parts into the reducer, so that maintenance of internal parts of the reducer will not be damaged.
3, reducer used in a variety of optional coupling type, but it is best not to use a steel fixed coupling, the coupling device is more difficult, once the device will increase the load will be defective , Easy to form the bearing damage, and even the formation of the output shaft fracture.
4, miniature bevel gearbox fixed is very important, to ensure that the smooth and strong, in general, we should reducer installed in a degree of foundation or base, but also the oil tank oil tank should be able to remove, and cooling air cycle fluent. Reducer fixed is not good, the foundation is not reliable, it will show the formation of vibration and other scenes, will make the bearings and gears have been unnecessary damage.
5, the reducer transmission coupling should be installed when necessary protective installation, such as the connector with a protrusion or the use of gears, sprocket drive, etc., if the output shaft to accept the radial load is large, it should be used to enhance type.
6, reducer position to ensure the operation of the staff, including easy access to the cursor, ventilation plug and drain plug and other status. After the completion of the reducer, the consoles should be in accordance with the specific order to reflect the accuracy of the status of the device to determine the integrity of the fasteners and so on.
7, before the operation of the reducer, but also to do the preparatory work, the oil pool of the vent hole plug removed into the ventilation plug, open the oil plug plug screw to reflect the oil line height, add smooth oil beyond the oil level plug Hole overflow, and then screw on the oil plug and be sure, you can start trial run.
8, reducer test run time can not be less than two hours, the normal operation of the specification is smooth, no vibration, no noise, no leakage, no impact, if the abnormal situation should be cleaned in real time.

Installation and reducer of axle reducer and precautions and installation.

First, the installation of shaft-mounted reducer
(A) the relationship between the reducer and the installation of the working machine
In order to avoid the work machine spindle deflection and in the reducer bearing on the additional force, the distance between the reducer and the working machine, without affecting the normal working conditions should be as small as possible, its value is 5-10mm.
(B) cycloidal speed reducer and work machine connection
The reducer is directly mounted on the working machine spindle, and when the reducer is running, the counter-torque acting on the reducer housing is installed on the reducer chassis or is balanced by other methods. Machine directly match the other end with the fixed bracket connection.
(C) the installation of anti-torque bracket
The counter-moment bracket shall be mounted on the side of the working machine towards which the reducer is oriented to reduce the bending moment attached to the working machine shaft. The counter-moment bracket and the sleeve of the fixed support link use elastomers such as rubber to prevent the occurrence of deflection and absorption of the generated torque ripple.

How to do the lubrication of the planetary gear reducer do it.

precision gearmotor and other reducer when running the same need to lubricate the following, so not only can accelerate the operation of the planetary reducer, and can protect the normal work of the reducer. How to do the lubrication work on the planetary reducer? Look at the specific details of the following Shanghai rehearsal machine to elaborate on it
According to the travel Helical bevel gear motor bearing load selection grease, the heavy load should be selected into the small grease. In the high pressure work in addition to small penetration, but also a higher oil film strength and extreme pressure function. Calculate the grease based on environmental conditions, calcium-based grease is not easy to dissolve in water, suitable for dry and less water environment. When the grease is selected according to the working temperature, the main indexes should be the dropping point, the oxidation stability and the low temperature function. The dropping point can generally be used to evaluate the high temperature function. The actual working temperature of the bearing should be lower than 10-20 ℃. The use of synthetic grease temperature should be lower than the drop point 20-30 ℃.
