Mechanical Engineer 2002.6 Oblique Axis Reducer Liu Yuxin Wang Yanxiu 2 4. Baoding Gas Company, Baoding, Hebei, 712. Baoding Yimian Group Co., Ltd., Baoding, Hebei, 751 At present, the speed reducers produced by most reducer factories are in accordance with national standards. Made by series, its input and output axes are not parallel or intersect at 90. There are few oblique crosses. Although oblique crossings are used sparingly, they can sometimes be needed and can even play an important role.
For example, a user needs to install a waxing device on the original sizing machine. The side shaft of the sizing machine and the main machine are oblique. To transfer power from the side shaft to the upper roller, it is necessary to reduce the speed and adjust the output shaft. Direction, the measured cross angle is 3 users put the input and output shaft transmission ratio is 185, the error does not exceed 1. To this end, we designed and manufactured the skew axis reducer.
1 Transmission plane unfolding and transmission principle The transmission plane is unfolded.
The transmission is divided into a part of the shifting zone and a part of the changing angle zone. From the side axis to the 3 axis is the shifting zone, and the 3rd to 4th axis is the variable angle zone.
The power of the transmission line is transmitted from the 34-tooth sprocket on the side shaft to the worm on the 1 axis to drive the worm on the 1 axis. The worm drives the worm wheel on the 2 axes to form the first stage shift, the transmission ratio = 146; the 220 teeth on the 2 axes and The 3-axis is 0-toothed to form the first-order shift, 3=20 is 0; the 3-axis 732 tooth is transmitted to the 4-axis 224 to realize the turning direction and the shifting 4=2, 82, 8. At this time, the 4-axis and The three axes are crossed with each other, the angle is 3, and the direction of rotation is the helical gear transmission. Since this part mainly aims to change direction, the gears of the selected gear are the same, and the deflection direction is the gear For the adjustment of the direction of the rotation and the direction of rotation, select the driving wheel 224 teeth left-handed, do 1=2 passive wheel 1224 tooth right-handed, 2=5 2 theoretical calculation 3 conclusion in selecting the direction of the two gears and the angle of the helix On the top, if the driving wheel is right-handed and the driven wheel is left-handed, the deflection angle will be clockwise; if the driving wheel is left-handed and the passive wheel is right-handed, the angle of deviation will be counterclockwise.
The skew shaft reducer has been put into use by the user and has been well reflected, which has brought considerable economic benefits to the user.
Emphasis on simplicity and practicality under the premise of work requirements, reducing instability.
The price is low. The low-volume production cost of this machine is less than the productivity of similar functional machine tools produced in Taiwan. Processing productivity 0 = 3, hours.
Beautiful appearance. From the perspective of ergonomics, the design of the machine tool has been considered in many aspects such as the vision of the machine operator's layout operation panel color line operator. Yang Guang and theoretical research.
