The 'integration of industrialization and industrialization' is not only about integrating information technology into mechanical products, accelerating the development of mechanical products to digital and intelligent, and realizing the improvement of traditional mechanical product functions and reliability; it is also not only about applying information technology to machinery enterprises.

 

Operation management enables the development , production and enterprise management to informatization, automation, and networking, and greatly improves the operation and management level of the enterprise; the in-depth advancement of 'informatization and industrialization' can promote the establishment of new development concepts and promote capabilities ,Wholesale Bevel Helical Gearboxes Product level, market model, service system and other aspects of innovation to improve the efficiency and effectiveness of design, processing and manufacturing, corporate management and marketing services.

 

The fifth is the 'green first' strategy. Energy conservation, emission reduction and environmental friendliness should become the basic requirements that the machinery industry itself must pay attention to during the 'Twelfth Five-Year Plan' period, especially for thermal processing enterprises that are high energy-consuming links in the machinery industry.

 

The machinery industry must actively develop high-efficiency and energy-saving products, vigorously develop new energy equipment, and provide advanced equipment for users in all walks of life to save energy, reduce consumption and reduce emissions.

 

At the same time, the design and manufacturing of mechanical products must pay more attention to the green concept that reflects the full life cycle, and factors such as 'high efficiency, low pollution, recyclability, and reusable resources' must be put in priority. It is necessary to develop remanufacturing of mechanical products and adhere to the new industrialization path of green manufacturing and circular economy.

There is no additional slip loss to change the pole pair speed regulation, and the efficiency is high; the control circuit is simple, easy to maintain, and the price is low; it can be combined with the stator voltage regulation or electromagnetic slip clutch to obtain smooth speed regulation with higher efficiency.

Stepless speed regulation cannot achieve stepless and smooth speed regulation. And due to the limitation of the motor structure and manufacturing process, usually only 2 to 3 kinds of pole pairs can be achieved, and the speed range is quite limited. Frequency conversion speed regulation has no additional slip loss, high efficiency, and wide speed regulation range; it can save electricity and protect the motor for long running time under low load or frequent start and stop occasions.

The technology is more complicated and the price is higher. The speed regulation of commutator motor has simple structure of AC synchronous motor and good speed regulation performance of DC motor; power supply voltage at low speed and back EMF natural commutation at high speed, reliable operation; no additional slip loss, Parallel Shaft Gearboxes high efficiency, and applicable It is suitable for the start and speed regulation of high-speed and large-capacity synchronous motors.

The overload capacity is low, and the original motor capacity cannot be fully utilized. Cascade speed regulation can feed back and utilize the slip energy generated in the speed regulation process. High efficiency; the capacity of the device is proportional to the speed adjustment range, and is suitable for 70%-95% speed adjustment.

The power factor is low, there is harmonic interference, and there is no braking torque during normal operation. It is suitable for loads that operate in single quadrants. The stator voltage and speed regulation circuit is simple, the device is small in size, and the price is cheap; it is convenient to use and maintain. The slip loss is increased during the speed regulation process.

In particular, pay attention to ensure the matching tolerance of the shaft and the inner hole of the felt ring. The gearboxes are all equipped with vents in structure. Therefore, when installing the gearbox and the motor, be sure to find the alignment and leveling to ensure that they are concentric. Therefore, the amount of oil must be appropriate and cannot be added. In this way, part of the oil flows back to the oil pool, and part of the oil leaks out of the box along the shaft through the bearing.

For the oil leakage of the non-shaft extension cover, the main reason is that the clearance between the end cover and the box body is large. And a drainage hole communicating with the felt groove is opened on the end cover. The circumferential speed of the large gear in the reduction box of the crane is generally not large.The guide plate is as large as possible in its rotation range, so that as little oil as possible enters the bearing. This structure of the reducer is used when the diameter of the gear is not much different from the diameter of the shaft.. It is the base of transmission parts and should have sufficient strength and rigidity.

The upper box cover and the lower box body are connected together by bolts.The reducer is mainly composed of transmission parts (gear or worm), shaft, bearing, box and accessories. In order to simplify the process and reduce the cost of a single-piece reducer,China Explosion-proof Gear motors Manufacturers a steel plate welded box can be used. The box is an important part of the reducer.

Deep groove ball bearings are used for both shafts. At this time, the gear and the shaft are fixed in the circumferential direction by a flat key connection, and the parts on the shaft are axially fixed by the shaft shoulder, shaft sleeve and bearing cover.

The bottom surface of the lower box seat of the reducer adopts two longitudinal strips to process the base surface. The box is usually made of gray cast iron, and cast steel box can also be used for the reducer with heavy load or impact load. In order to avoid the possibility of splashing thin oil from falling off the grease, it can be separated by a stopper. The pinion and the shaft are made into one body, called the gear shaft.

It must be less than 2 times the rated output Wholesale Bevel Helical Gearboxes Manufacturers torque of the reducer. At this time, the overload capacity of the drive motor will continue to increase its output, which may cause the output bearing of the reducer to be affected. This is not only to protect the reducer, but also to prevent the output shaft of the reducer from being twisted.

Except for the broken shaft of the reducer caused by poor assembly concentricity at the output end of the reducer, if the output shaft of the reducer breaks, there are nothing more than the following reasons. First, the rated output torque of the equipped motor is multiplied by the reduction ratio, and the value obtained is in principle smaller than the product The rated output torque of the reducer provided by the sample is similar.

In theory, the maximum working torque required by the user. Second, the overload capacity of the drive motor and the maximum operating torque required in practice must also be considered. In particular, some applications must strictly abide by this criterion. First of all, the wrong selection caused insufficient output of the reducer. The force exceeds 2 times the rated output torque and twists the output shaft of the reducer.

This is mainly because if there is a problem with the installation of the equipment, the output shaft of the reducer and its load are jammed. Some users mistakenly think that as long as the rated output torque of the selected reducer meets the working requirements, it is not true. Secondly, in the process of acceleration and deceleration, if the instantaneous torque applied to the output shaft of the reducer exceeds twice its rated output torque, and this acceleration and deceleration are too frequent, the reducer will eventually be broken
