Description

、 Instruction of creation (1) [Technical field of the new type] It belongs to a power transmission wheel structure of a double-shaft circular saw machine. It uses a special setting of a double-layer transmission wheel to pass a transmission belt. The circular saw blade on the shaft and the pre-cutting blade on the passive shaft rotate in the opposite direction, and the first and second transmission belts will not interfere with each other. Therefore, this creation belongs to the technical field of power transmission of a round miner. [Previous technology] According to the circular saw machine generally used for sawing wood materials, it can be divided into single-knife = double-knife shaft. The double-knife shaft is mainly used for more burrs or more brittle materials on wood to reduce its burrs or It broke during the sawing process, and the power transmission structure of the double-blade shaft of the conventional circular saw machine is mainly shown in the first and second figures. The machine is provided with a height-adjustable base 10 on the machine. On the body 10 = there is a driving element 11 which drives a driving shaft 12 with a circular saw = 15 using a belt, and a driving wheel 16 is provided at one end of the driving shaft 12 different from the circular saw blade 15. In addition, the machine is provided with a passive shaft 20 on the side of the base body 10. The passive shaft 20 is provided with a pre-cutting blade 21 which is in line with the circular saw blade 15, and the other end of the passive shaft 20 is provided. There is a passive wheel 22, and an elastic transmission belt 23 is wound between the driving wheel 16 and the passive wheel 22. At the same time, in order to make the circular saw blade 15 and the pre-blade 21 rotate in the reverse direction, the elastic transmission belt 23 is inverted 8 The staggered shape surrounds the active and passive wheels 16, 22; however, there are some problems in its use, such as the second and third wheels. As shown in the four figures, due to the different thickness of the wood, in order to achieve a better sawing effect M268122, creative instructions (2) 'the position of the body 10 of the circular saw blade 15, and' for the dimensional transmission belt 23 at any time Very high, intangible properties are not resistant to high yield reduction; Moreover, the high temperature rise due to heavy friction in the central part will be more likely to be loose due to lack of power transmission structure through the circular saw machine. Based on this experience, we can make great efforts based on this experience, and actively seek for a successful structure that finally succeeds. At the same time, it can be adjusted according to the thickness of the wood, so it is necessary to change the seat frequently. ^ The active and passive shafts are changed. The effect of the gap between 2 and 20 is lost, so you must use the elastic effect of the bullet Up to do 2 goals, but the general price, strictness, and cost of the elastic transmission belt 23, and this kind of elastic transmission belt 23 due to material cracks 'As a result, it will also increase its maintenance costs and the generation of power transmission stacks (such as degrees, and it breaks when it overheats, and it will also explain that the existence of my transmission structure is' easy', in other words, to enhance its competition. The person seeking the solution to the above habits makes a truly effective reduction of the structure. The fourth graphical transmission, the damage affects the design can not be damaged. (Considering, it will) 'If the understanding of simultaneous transmission with 23 is not perfect' "Chengfu's long-term circular saw with economical and multi-year phase structure has elasticity. This is due to the elasticity of the high temperature resistance during operation. . Due to the current high cost and transmission structure benefits. Industry-related problems and needs of the research machine When the double-blade shaft is long and the life belt 23 is used, due to the characteristics, the conveyor belt 2 3 is tired and the double-blade shaft is habitual. And development, the efficacy of power transmission life Page 6 M268122 Creative instructions (3) [new content] Therefore, the actual circular saw machine fruit. In addition, the original circular saw machine has two blades, and the original realization of this creation reaches the upper body, and the active rod of the circular saw blade, the passive shaft driving wheel and the passive blade can transmit the power in the opposite direction, and the sleeve is turned to the One end is provided with a drive-out wheel, and then the wheel ', and the front belt of the active shaft layer transmission wheel is wound around the double-layered active wheel in an inverse direction, and the passive shaft is fixed on the bottom edge of an adjusting wheel, and then another eye shaft power is used. The transmission is mainly through the function described above and the drive shaft is provided on the body, and the wheel is provided with a rotation between the wheels; the transmission structure is connected to the active fixing plate of the motor vehicle by the rod side harness between the two wheels of the active wheel.
