时间:2018-11-04 11:39   tags: products information  

XNUMX. The original information and data of the design
1. The type, specification, speed, power (or torque), starting characteristics, short-time overload capacity, moment of inertia, etc. of the prime mover.
2. The type, specification, purpose, speed, power (or torque) of the working machine.Work system: constant load or variable load, variable load load diagram; starting, braking and short-time overload torque, starting frequency; shock and vibration degree; rotation direction, etc.
3. The connection mode of the prime mover and the reducer, whether the shaft extension has radial force and axial force.
4. Installation type (relative position of reducer and prime mover, working machine, vertical type, horizontal type).
5. Transmission ratio and its allowable error.
6. Requirements for size and weight.
7. Requirements for service life, safety and reliability.
8. Environmental conditions such as ambient temperature, dust concentration, air velocity and pH; lubrication and cooling conditions (whether there is circulating water, lubrication station) and restrictions on vibration and noise.
9. Requirements for operation and control.
10. The source and inventory of materials, blanks, standard parts.
11. The manufacturing capacity of the manufacturing plant.
12. Requirements for batch size, cost and price.
13. Delivery deadline.The first four items mentioned above are necessary conditions. Other aspects can be designed according to conventional rules. For example, the design life is generally XNUMX year. When used in important occasions, the reliability should be higher.
XNUMX. Select the type and installation type of the reducer.
XNUMX. Preliminarily determine the performance level of various technological methods and parameter selection, preliminarily determine the materials of gears and main parts, heat treatment technology, finishing methods, lubrication methods and lubricants
XNUMX. Determining the number of transmission stages According to the total transmission ratio, determine the number of transmission stages and the transmission ratio of each stage.XNUMX. Preliminary geometric parameters Preliminary calculation of gear transmission center distance (or pitch circle diameter), modulus and other geometric parameters.
XNUMX. The overall plan design determines the structure of the reducer, the size of the shaft, the span and the bearing model, etc.
XNUMX. Check the strength of load parts such as gears, shafts, keys, etc., and calculate bearing life.
XNUMX. Lubrication and cooling calculation XNUMX. Determine the accessories of the reducer
XNUMX. To determine the carburizing depth of the gear, it is necessary to calculate the tooth profile and tooth profile modification amount and other process data.
XNUMX. Drawing construction drawings should implement relevant national and industry standards in the design.
