First, the design of raw materials and data

1. Types, specifications, speed, power (or torque), starting characteristics, short-time overload capacity, 💫moment of inertia, etc..

2. Types, specifications, uses, spee𓄧d, power (or torque) of the working machines. Work sys🐬tem: constant load or variable load, variable load diagram, start and braking, short-term overload torque, starting frequency, impact and vibration degree, rotation direction, etc..

3, the prime mover is connected to the reducer, whether the shaft has radi🧸al force and axial force.

4, installation type (r🐎educer and the prime mover, the relative position of the machine, vertical, horizontal).

5, transmission ratio and its allowable error.

6. Requirements for size and weight.

7. Requirements for servi𝕴ce life, safety and reliabilꦓity.

8. Environmental conditions such as ambient temperature, dust concentration, air flow rate and pH, lubricatio🌌n and cooling conditions (whether circulating water, lubrication stations), as well as restrictions on vibration and noise.

9 、 requirements for operation and control.

10, ma🗹terials, rough, stand😼ard parts, sources and inventory.

11. Manufacturing capacity of 🔜🎐a manufacturing plant.

12. Requirements for lot size, cost and price.

13, delivery time.

The first four ℱare necessary, and other aspects can be conventionally designed, for example, the design life is generally "years.". For important occasions,✨ the reliability should be higher.

Two, selec♑t the type of reduc𓆏er and installation type

Three, the initial process and parameters

The selected level of performance, the initial ﷺgear and main parts materials, hಌeat treatment, machining method, lubrication and lubrication oil.

Four, determine the transmission series

According to the total transmission ratio, the series of transmission and the transmission ratio at different lℱeཧvels are determined.

Five, the initial geometric parameters

Initial gear transmission center distance (or ღpitch diameter), modulus and other geometric parameters.

Six, the overall design

Determine t☂he s✱tructure of the reducer, shaft size, span and bearing type, etc..

Seven, School

Check the strength of the gears, sh🙈afts, ke✅ys, etc., and calculate the life of the bearings.

Eight. Calculation of lubrication and cooling

Nine. Determine the accessories of the reducer

Ten, determine gear carburizing depth

When necessary, the data of too🅠th shape and tooth direction modification are calculated.

Eleven, drawing drawings

The relevant standards of theꦚ state and industry should be implemented in the design.
