According to the design requirements of the device, the required motor power is 22 kW, the motor speed is 1470 r/min, and the output speed is 45 r/min. Since the required gear ratio is large, it is preferable to further connect a planetary gear train to the output tie rod H of the epicyclic gear train based on the illustrated scheme, and the inner ring gear of the first-stage epicyclic gear train by the magnetic powder brake. b Braking, the calculated braking torque is 1076.5N/m, so the braking torque of the brake should be at least 1100N/m. The CZ-100 magnetic powder brake is selected to have a diameter of about 630 mm and an axial dimension of about 260 mm. The required diameter and axial dimensions of the two-stage planetary gear reducer are about 400 mm and 580 mm, respectively, and the shape of the magnetic powder brake can be seen. The size is larger than the size of the main part of the device, resulting in an unbalanced shape. Therefore, the solution must be improved to reduce the braking torque, so that the layout of the device is reasonable, the shape is harmonious, the appearance is beautiful, and the manufacturing cost of the device is reduced.
Improvement and innovation of the start-drive scheme, the proposal of the innovative scheme When designing the epicyclic gear train, it is customary to use the center wheel a as the input member, the tie rod H as the output member, and the inner ring gear b as the fixed member or the control link. There are many advantages to doing this. However, for the design examples discussed in this paper, in order to meet the requirements of reducing the braking torque, this design idea needs to be changed.
The transmission efficiency analysis of the scheme can be derived from the Kpe/Hec formula, and the transmission efficiency of the device in the initial scheme into the steady-speed operation phase is G=1-iHabGH1-iHab: GH-the efficiency of the turnover train conversion mechanism. Similarly, the transmission efficiency of the first-stage epicyclic gear train of the improved scheme under the steady running state is G=GH-iHab1-iHab. Since the GH is close to 1 and less than 1, the difference between the two types of transmission efficiency values ​​is small. By multiplying the efficiency value of the equation by the efficiency G1 of the fixed-shaft transmission pair and the efficiency G2 of the second-stage planetary gear train, the transmission efficiency of the device in the improved scheme can be obtained. From the above analysis, it can be seen that the transmission efficiency of the device in the improved scheme is slightly lower than the initial scheme.
Further improvement of the scheme In the above-mentioned process of improving the design, the author uses the creative thinking in the innovative design, and the creative thinking activity can be further expanded, and then proposes a variety of alternative design schemes, for example, based on the illustrated scheme. The motor and the magnetic powder brake are interchanged, and the start-drive scheme is shown. In this scheme, the center wheel a is still used as the input member, and the inner ring gear b is used as the brake control link. In addition to the advantages of reducing the braking torque, the scheme has the input and output coaxiality of the scheme. The characteristics of the line layout, the overall layout is more reasonable, the appearance of the device is more coordinated, and at the steady speed, the transmission efficiency is slightly higher but also to be seen, and the two improved design schemes shown are added. The first-stage fixed-shaft transmission pair, and the speed-up transmission pair appears on the transmission route from the input member to the brake link, which is a deficiency of the two improved solutions with respect to the initial design shown, but this disadvantage Only present in the start-up phase of the device. At the end of the start, after the device enters the steady speed operation state, the speed increase transmission pair stops running.
The use of the characteristics of creative thinking, the comprehensive use of a variety of thinking skills, jumping out of the habit of habitual thinking, is very important for the introduction of innovative design and the improvement of the original program. Only by using creative thinking consciously in the design process can we achieve high-quality, high-efficiency design, and then develop a variety of new products that meet functional requirements, high performance, good quality, low price, and competitive market.
