Service HotlineAt present, Portlandshaft retaining rings are mainly divided into three categories: elastic retaining rings for shafts, flattened wire retaining rings for shafts, and wire retaining rings for shafts. Among them, the spring retaining ring for the shaft is generally installed with circlip pliers, and the flattening wire retaining ring for the shaft and the wire retaining ring for the shaft are generally installed with a sharp screwdriver or needle-nose pliers. The defects and deficiencies of these two methods will be discussed in detail below: First, the above two installation methods require the operator to use a large force to open the retaining ring, which is more laborious; For the installation of the flattened steel wire retaining ring for the shaft and the steel wire retaining ring for the shaft, because the wire retaining ring has low elasticity and has no force point, it is very easy to cause the retaining ring to break or the installation tool to slip during the installation process. Higher skills and experience can be competent for the installation of wire retaining rings.
The main purpose of the screw is to make the industrial product form a fixed one. In use, it often happens that the teeth cannot be closely attached, the screw head will be broken if the screw is locked too hard, or the tooth pattern is not properly locked, etc., and the use conditions are not met, all of which are quality. the problem of accuracy. Screws are mass products, not handmade works of art. In mass production, the purpose is to achieve high-precision and stable quality and popular prices to supply consumers. The accuracy of screws is usually 6g, and the rough screws used in construction projects are 14g. The value of screws is very important. In the world, there are examples of automobile factories going bankrupt because of poor screw quality; there are also examples of planes falling and vehicles being overturned because of poor screw quality.
The circlip lifting and tightening mechanism includes a lifting mechanism and a tightening mechanism; the lifting mechanism includes a lifting cylinder and a ball screw; the output shaft of the lifting cylinder is connected with the ball screw; the ball screw drives the tightening mechanism to achieve up and down move; the tightening mechanism includes a tightening motor, and the output shaft of the tightening motor drives a pinion sleeved on the output shaft to rotate; the pinion drives the largest gear meshed with it to rotate, and the largest gear is driven by The second largest gear meshed with it rotates; the diameter of the first largest gear is the same as that of the second largest gear; the lower ends of the rotating shafts of the first largest gear and the second largest gear are equipped with rotating discs, and each rotating disc is fixedly installed A probe; two probes can be inserted into the two holes of the circlip at the same time, and the circlip can be tightened or loosened as the motor rotates.
The side gear thrust washer used in the automobile differential is a flat washer, which is installed between the differential housing and the side gear to prevent the side gear from retreating. Due to the high-speed rotation of the side gear when the differential is working, it is necessary to ensure that the contact surfaces on both sides of the flat gasket are well lubricated.
The material of the round head three PortlandPortlandPortlandcombination screw is divided into iron and stainless steel. The iron ones are made of different iron screw wires. Generally, the wire of the PortlandPortlandPortlandcombination screw is 1010, 1018, 10B21 and so on. 10B21 is used to make 8.8 grade PortlandPortlandPortlandcombination screws. Like 8.8-grade socket head Portlandcap screws, 10B21 wires are often used to make them. When done, go to heat treatment. After heat treatment, remove hydrogen and electroplating. This is to prevent the PortlandPortlandspring washer of the socket head Portlandcap screw from breaking. Stainless steel PortlandPortlandPortlandcombination screws, in the PortlandPortlandPortlandcombination screw market, generally refer to stainless steel SUS304 PortlandPortlandPortlandcombination screws. 201 PortlandPortlandPortlandcombination screws generally do very little. Few manufacturers of round head three PortlandPortlandPortlandcombination screws produce 201 PortlandPortlandPortlandcombination screws. Because the hardness of the screw wire of stainless steel 201 is not well controlled, it is easy to produce cracks. Introduction to the basic knowledge of electroplating round head PortlandPortlandPortlandcombination screw electroplating generally refers to the de-plating of iron PortlandPortlandPortlandcombination screws. Electroplating is divided into environmental protection and non-environmental protection. Commonly used PortlandPortlandPortlandcombination screw electroplating colors include green color zinc, green blue zinc, green white zinc, green nickel, red color, white zinc, white nickel, etc. Cross recessed PortlandPortlandPortlandcombination screws, hexagon combination bolts and self-tapping PortlandPortlandPortlandcombination screws are used in the same way as the corresponding cross recessed screws, hexagon head bolts and self-tapping screws. The main feature of these PortlandPortlandPortlandcombination screws is that they are equipped with corresponding washers, which are very convenient to use.
