The ZQ Series cylindrical gear reducer for coal mine winch plays the role of matching the speed and transmitting torque between the prime mover and the working machine, and is also the main part of the ground mine hoist.Coal mine winch reducers are widely used in modern machinery. In the 1970s and 1980s, the world's reducer technology has developed greatly.
The main factors that promote the improvement of the level of coal mine winch JZQ850 cylindrical speed reducer are:
(1) Development and improvement of hard tooth surface technology, such as large grinding technology, carburizing and quenching technology, gear strength calculation method, shaping technology, deformation and optimization design method, root reinforcement and its meta-transition, new structure, etc. .
(2) With good materials, various high-quality alloy steel forgings are generally used, and the quality control of materials and heat treatment is high.
(3) The structural design is more reasonable.
(4) The machining accuracy is improved to ISO5-6.
(5) Improved bearing quality and life.
(6) The quality of lubricating oil is improved.
Classification of coal mine winch JZQ Helical Gear Box drive reducer: The Helical Gear Shaft Mounted Gear Boxcan be divided into two categories: general reducer and special reducer according to the application. The design, manufacture and use characteristics of the two are different. According to the performance, it can be divided into adjustable gear ratio reducer, fixed ratio gear reducer or grading variable speed reducer, stepless variable speed reducer; according to its transmission structure can be divided into gear reducer, other new reducer and so on. In some precision, ultra-precision mechanisms with high speed requirements and complicated working processes, a large number of new speed reducers are used.
high precision motor planetary gearbox are the most commonly used because of the mature gear manufacturing technology, low working environment requirements and convenient maintenance. There are many types, types and types of wholesale 2 speed planetary gearbox. At present, there are more than 40 types of reducers for the line (country). The types of gear reducers are divided according to the gear tooth profile and tooth profile curve used; It is a reducer with different structure designed according to the needs of use; the type of Electric Motor Reduction Gearbox is designed based on the basic structure, according to the factors such as tooth surface hardness, transmission series, discharge type, assembly type, installation type, connection type and so on. Different reducers.
1.2m coal mine winch reducer, 1.6m mine winch reducer, 2m mine winch hoist reducer and 2.5m mine winch reducer load classification and reducer connection work machine load state is more complicated, the impact on the reducer is very Large, is an important factor in the selection and calculation of the reducer. The load state of the reducer is the load state of the working machine (slave). It is usually divided into three categories: 1 uniform load, 2 medium impact load, and 3 strong impact load. . The design plan should be appropriately enlarged according to the type of load to ensure the service life of the reducer. When designing the reducer, according to the selection conditions of the working machine, technical parameters, performance of the power machine, economy and other factors, compare the dimensions of the reducer of different schemes, transmission efficiency, load capacity, quality, price, etc., choose the most suitable planetary transmission variator.
