1. Basic concept: Linear bearing is a linear motion system with high precision, low cost and low friction resistance. Linear bearings are used in combination with guide shafts, and use the rolling motion of balls to achieve infinite linear motion. Since the bearing ball is in point contact with the shaft, the load is small. …

Industrial automation is a trend in which automatic control and automatic adjustment devices are widely used in industrial production to replace manually operated machines and machine systems for processing and production. Under the conditions of industrial production automation, people only indirectly take care of and supervise the production of machines.
(1) For pulleys with parallel drive shafts, the tolerance of the parallelism of the two axes is (0.15/1000)L (L——the center distance between the two shafts), the wheel width middle plane of the two wheels should be on the same plane, and the tolerance is 0.5mm. (2) The geometric center lines of the gear teeth of …

Vibration barriers refer to problems caused by vibration during processing, inspection, and measurement. Vibration obstacles will have a significant impact on machining accuracy, quality, and inspection results, so it is necessary to select and implement appropriate vibration elimination and anti-vibration products. The main vibration obstacles are as follows.
1. Turning tool Generally uses the following types of turning tool tip: (1) Rough turning tool: It is mainly used to cut a large number of excess parts to make the diameter of the workpiece close to the required size. When rough turning, the surface finish is not important, so the tip of the turning …

The back of the polyurethane belt backing timing belt is used to bond and wrap the tensile element. It should have good flexibility and flex fatigue resistance, not easy to age, good oil resistance, and abrasion resistance, on the inner surface of the belt back A sharp-angled groove with an appropriate size can not only improve the flexural fatigue performance of the toothed belt due to process requirements, but also allow the intercepted air between the belt and the gear teeth to escape during operation to eliminate part of the noise.
Refers to the ability of a material to resist local deformation, especially plastic deformation, indentation or scratches. It is a measure of material softness and hardness.
The Preferred Path for eliminating hazardous conditions is to eliminate the hazard through improved design.
In the cutting process, the thin wall is easily deformed by the cutting force, which leads to an oval or a “waist shape” with a small middle and large ends.
Ancient machinery provides a new world for the development of human beings. With the continuous innovation and change of machinery, human ideas are also changing.
There are many reasons for the deformation of aluminum parts, which are related to the material, the shape of the parts, and the production conditions.
A set of reliable plastic mold design is mainly reflected in the quality of the molded plastic products (appearance quality and dimensional stability), convenient, rapid, and concise processing and manufacturing, which saves money and manpower, and leaves room for correction and improvement.
It is worth pointing out that no “lighthouse factory” has completed digital transformation alone. They all rely on partnerships to acquire or jointly develop new knowledge. And Microsoft has become the choice of many business partners.
The task of mechanical structure design is to draw a specific structure diagram based on the design task on the basis of the overall design conception, and to draw a specific structure diagram to achieve the functions required by the design.
Surface roughness Ra is a symbol often used by our machines. It is basically our old friend. If that drawing does not have it, it is estimated that the drawing will be scrapped. It is such a symbol for dealing with every day. Do you know why 0.8 is used , 1.6, 3.2, 6.3, 12.5, and not other numbers? I believe that members of the community have also encountered this confusion when they are learning and using it, but they have not studied the answer in detail. All of this must start with the great mathematics, and now I will explain it in detail.
