In actual use, when the system for controlling the gear transmission adopts the automatic control servo system, the system will oscillate because of the transmission gap plus the inertia of the transmission device, which is what is commonly called the part oscillation. European and American countries have adopted a two-piece combined gear transmission method in the low-power mechanical transmission system-instrument industry, which has achieved quite satisfactory results. The working mechanism is to use two pieces of / 0 modulus gear trains to form a combined gear on one shaft, one of which is fixed on the shaft, and the other is fixed on the shaft and riveted. The two can be rotated relative to each other, and the two pieces are connected by springs. In the transmission system, the main gear piece functions to transmit torque and movement. The gear plate is only responsible for eliminating the lateral clearance when the gear is bonded, thus achieving smooth operation of the system.
In the case of using an automatic control servo system to control the gear transmission, if a combined gear reducer that eliminates the backlash is used, it should be quite satisfactory. The principle is clear, the gear gap is eliminated, the friction torque of the transmission chain is increased, and the oscillation of the parts of the system is suppressed. Although the sensitivity will be slightly affected, the transmission accuracy is correspondingly improved.
The structure and processing drawing of the three-piece combined cylindrical gear is a schematic diagram of the structure of the three-piece combined cylindrical gear. It is mainly composed of a combined gear wheel seat, a side gap compensating wheel and a gear upper cover. The gear wheel seat serves as the main support and transmission. The side gap compensation wheel acts as a backlash compensation between the teeth, and the gear upper cover functions as a limit and transmission. The combined gear wheel housing and the gear upper cover are positioned by two round pins, and six hexagon socket head screws are used. The backlash compensation wheel can be flexibly rotated between the combined gear wheel housing and the upper cover of the gear. In order to ensure the accuracy and quality of the combined gears are completely consistent, in actual machining, the gears are manufactured according to standard accuracy. The gap compensator wheel is positioned by the three process cylindrical pins and the combined gear wheel seat, the gear upper cover is covered, the round pin is used for positioning, and the combined gear wheel seat, the side gap compensating wheel and the gear upper cover are fixed into one by screws. The three pieces are simultaneously processed by the gear. After the shaving or grinding, the assembly is disassembled, the sharp edge burrs are removed, and the assembly clearance is ground, so that the side gap compensating wheel can flexibly rotate in the combined gear. The absolute error of each positioning point measurement in the transmission system does not exceed the upper and lower, which fully meets the technical requirements of the system.
In practice, the three compression springs that provide thrust for the compensating wheel need to be carefully designed. The maximum working load of the spring must be used as the basis for the spring design according to the rated rotational speed specified by the design. The elastic force of the compression spring should not be too large. Excessive elastic force will increase the friction torque during transmission, and the wear will also increase, which will affect the service life.
In order to ensure that the technical quality of the reducer device meets the technical design standard of the system, the design parameters of the drive gear and the driven gear of the reducer are deliberately consistent, so that the main and driven gears can complete the machining of the gear at the same time. The complete consistency of technical quality is guaranteed.
The application of three-piece combined cylindrical gears has been driven by the continuous development of industrial technology, especially the rapid development of robot technology, which has promoted the development of transmission 1 machinery. The emergence of a three-piece combination gear has its background. For industrial technology, how to achieve modernization, improve the technical content of products, and improve production efficiency is a top priority. We still lag behind the developed countries in many industrial technologies. The ratio between energy consumption and "34" remains high, indicating that China's industrial technology still has a gap with developed countries.
Conventional small capacitor aluminum shells are formed by two methods, one is by continuous stretching using a thin aluminum plate, and the other is cold extrusion of aluminum particles. The preparation of the aluminum particles is obtained by punching and blanking the aluminum plate by punching. Since the aluminum particle structure is circular, the material utilization rate is extremely low regardless of the layout.
