Transmission mechanism capable of simplifying layout logic

Abstract

The invention provides a transmission mechanism capable of simplifying layout logic. The transmission mechanism is of a pure mechanical structure in whole and can be applied to the occasions such as power distribution, rotation speed change, clutch output and mechanical control. Seven application examples are adopted for explanation; because the vitality of mechanical transmission mechanisms relies on creation, under the situations that novel methods constantly emerge, available technologies are developed on the basis of the methods and the application range of a pure mechanical transmission mechanism is constantly narrowed, novel mechanical transmission mechanisms need to be created constantly, novel technical effects are needed, and the application range needs to be expanded.

Description

technical field [0001] The invention relates to the field of mechanical transmission, in particular to a transmission mechanism of at least one power source and at least one output end. Background technique [0002] At present, in the transmission mechanism of at least one power source and at least one output end, there are unavoidable technical design links of the power transmission route, such as power switching of a single power source driving multiple output ends, multiple power sources jointly driving several The power combination at the output end, however, due to the high degree of mechanical and electrical integration at the present stage, electrical technology is often used to implement the existing programming torque transmission logic problems, and less emphasis is placed on implementing, summarizing, improving, and even solving in the mechanical transmission mechanism. In addition, if a mechanical transmission mechanism is judged on the rationality of the actual ...

The technical solution adopted by the forklift is that the engine selectively drives the rear wheels of the forklift and the hydraulic pump. The hydraulic pump drives the lifting cylinder and the swing cylinder through the two manual two-way control valves controlled by the operation. This is a very practical solution, but it can be seen that The designer intentionally avoided the all-mechanical transmission scheme, and cleverly made a subtractive design with an oil pump, which resolved the existing three output terminals into a substantial parallel two output terminals, thus also resolving the logical technical difficulties of arranging any combination of outputs. In this example, if all mechanical structures are used, one power source can drive the three output terminals with a mechanical transmission mechanism. The three output terminals have any combination of arrangement logic, and it is difficult to achieve mechanical transmission. Of course, the It is difficult to do in addition to the structure, but also includes factors such as cost and practicality that are difficult to balance

[0005] One of the power sources is an electric motor, and it is necessary to switch between several speeds during use. According to conventional thinking, it is easy to think of frequency conversion technology as the first choice. In fact, the mechanical speed change method contains the practical value of controlling the change of torque. Commonly known as the "four-two dialing jack" feature, it can be seen that the frequency conversion technology cannot fully replace the mechanical transmission mechanism. When an occasion that needs to increase the torque by changing the speed, we still cannot do without the gearbox. The gearbox is composed of a series of shafts and gears. The fully enclosed transmission mechanism relies on a gear or a group of gears to slide axially when shifting, increasing or decreasing the meshing times of the gear pairs and the replacement form of the meshing of different sizes of gears to change the power transmission route. Shaft spacing, gear strength, calculation modulus, and then the overall transmission design, sometimes it is even necessary to choose a shifting gear. The gear shaft is the radial carrier of the gear and the guide of the axial sliding gear, and also serves as the axial positioning of the fixed gear. At present, mass-produced finished gearboxes can be purchased, but the gearbox technical solution itself has the defects of large number of transmission pairs, long transmission chain and low transmission efficiency. It is a mature product in terms of mechanical transmission form, but it is not the same as above. The best gear shifting products

[0006] There is a technical solution for a take-up and pay-off machine. There are several winding reels for retrieving and releasing insulated wires with different wire diameters and uses. The power source is an electric motor or manual. In the layout logic design of the pay-off wheel, because the overall coordination accuracy of this take-up and pay-off machine is not high, the manufacturing process is simple, it is useful but the added value is low, it is obviously not easy to install multiple clutches or use a complex power distribution mechanism, the existing The take-up and pay-off machine connects the reel and the axle with a pin or a set screw to replace the clutch. The manual operation procedure is complicated and inconvenient. It is necessary to find a clutch with simple structure, convenient operation and convenient realization of programming logic. Way
