Description
[ technical field ] A method for producing a semiconductor device
The utility model relates to a power transmission technology especially relates to a power transmission structure for coating production.
[ background of the invention ]
In the coating production process, the power drive of the traction roller is generally driven by a decelerated motor, the rotating speed of the power is decelerated by connecting the motor with a gearbox, and the motor and the gearbox are in transmission connection, as shown in fig. 1, the internal and external spline tooth type coupling is adopted and consists of parts such as an inner gear ring with the same number of teeth and a flange half coupling with external teeth. The external teeth are divided into two tooth forms of straight teeth and crowned teeth, the crowned teeth are characterized in that the external teeth are made into spherical surfaces, the centers of the spherical surfaces are on a gear axis, the tooth side gaps are larger than those of common gears, and the crowned tooth coupling can allow larger angular displacement (relative to a straight tooth coupling), so that the contact condition of the teeth can be improved, the capacity of transmitting torque is improved, and the service life is prolonged. Moreover, when the gear coupling works, the two shafts generate relative displacement, and the tooth surfaces of the inner teeth and the outer teeth periodically perform axial relative sliding, so that tooth surface abrasion and power loss are inevitably formed, and therefore, the gear coupling needs to work in a good lubricating and sealing state.
The gear coupling has the advantages of small radial size, large bearing capacity and reliable work, is long used for shafting transmission under the working conditions of low speed and heavy load, and can be used for high-speed transmission such as shafting transmission of a gas turbine through the gear coupling with high precision and dynamic balance. Compared with other couplings, the coupling has the same size, the transmitted torque is maximum, and the two shafts are allowed to have larger parallel error. Meanwhile, the angular compensation of the crowned tooth type coupler is larger than that of a straight tooth type coupler, the crowned tooth type coupler is widely adopted at home and abroad, and the crowned tooth type coupler has high rigidity, flexibility and no elasticity, so the crowned tooth type coupler is not suitable for machinery which requires strict requirements on vibration reduction, buffering and two-axis centering, and is difficult to manufacture and cannot buffer and damp due to the fact that the crowned teeth need to be processed.
The tooth type coupler adopting the internal and external splines shown in fig. 1 is continued, because the internal and external spline small teeth are thinner, the adaptability to the use working condition is poorer, and under the condition that the motor bears alternating load, impact load or vibration is larger, the small teeth of the coupler are easy to be rapidly worn and even fail. Meanwhile, as the transmission structure is a closed structure, the lubrication condition of the spline small teeth cannot be observed under the condition of not disassembling; therefore, in the coating production and processing process, a gear coupling is adopted between the motor and the gearbox, so that the maintenance performance is poor, and the transmission stability cannot be effectively guaranteed.
