The use of mechanical equipment has gradually increased our demand for racks and gears, and gear racks have also ushered in good market development opportunities.Different mechanical equipment has different selection criteria for rack and pinion. The gap of a good rack and pinion is relatively small during transmission, so that a good transmission effect can always be achieved. Then it should be as much as possible. To reduce the gap of the rack and pinion transmission, let us understand together with the editor.

　　Large-scale CNC machine tools with large operating strokes usually use rack and pinion to achieve feed motion.When the feed force is not large, the double-thickness gear structure similar to the cylindrical gear transmission can be used to reduce the gap through the method of staggered teeth; when the feed force is large, the transmission structure of double thick gears is usually adopted.The feed motion is input by shaft 2, and the motion is transmitted to shaft 1 and shaft 3 through two pairs of helical gears, and then the rack is driven by two spur gears 4 and 5 to drive the worktable to move.The directions of the spirals of the two helical gears on the shaft 2 are opposite.If an axial force F is applied to the shaft 2 through the spring to make the helical gear produce a slight axial movement, then the shaft 1 and the shaft 3 will rotate through a small angle in the opposite direction, so that the gears 4 and 5 are in contact with the teeth respectively. The two tooth surfaces of the strip are close to each other, reducing the gap.The stability of rack and pinion in transmission The rack and pinion is quite stable during transmission, so it can be regarded as a relatively stable one among similar technologies, and it has its own characteristics.

　　The method of reducing the rack and pinion transmission gap needs to be treated according to different situations. In the above article, the editor has already introduced you clearly, and I hope that readers can help.Regardless of whether large-scale equipment or small equipment, gears play a particularly important role. We need the market to check the operating conditions of the gears. Seriously damaged gears need to be replaced in time, otherwise it will affect the use of the equipment. The gears play a role in the operation of the equipment. Plays an important role.
