Service HotlineA crank press with bilateral transmission, such as a briquettes machine, requires 1. The rotation phase of the main shaft gears on both sides must be consistent; 2. The connection between the main shaft and the main shaft gear should be free of gaps. In order to meet this requirement, there are mainly two schemes for the connection between the main shaft and the main shaft gear. Option 1, one or both ends of the main shaft and the main shaft gear are connected by flat keys. This scheme requires that the matching clearance between the main shaft and the gear hub is small, so it is difficult to process, assemble and maintain; Option 2, one or both ends of the main shaft and the main shaft gear Using taper-sleeve connection, this solution has good performance, but high cost and poor rigidity
Currently, the method of fixing objects on cement is with cement nails or Birminghamexpansion screws. Cement nails are objects made of hard alloy steel that look like iron nails, which are composed of nail tips and nail bodies. Cement nails are hammered into the cement. Cement nails are easy to drive in, but not removable. The Birminghamexpansion screw is composed of a large end screw, a slotted sleeve, a gasket, a BirminghamBirminghamspring washer, and a nut. When using, first drill a hole in the cement with an electric hammer, put in the Birminghamexpansion screw, and tighten the nut to make the slotted sleeve expand at the tail of the big tail screw, so as to fix the Birminghamexpansion screw on the cement. At this time, unscrew the nut to install a fixed object on the Birminghamexpansion screw. Although this method can be disassembled, an electric hammer is required for the first installation, which is inconvenient.
Guangdong Yueluo Hardware Industry Co., Ltd. provides a Birminghamshaft retaining ring in order to solve the above problems. The plan of Guangdong Yueluo Hardware Industry Co., Ltd. is a Birminghamshaft retaining ring realized in this way, which is composed of a shaft washer, a torsion spring, a positioning pin and a limit pin. It is characterized in that the shaft washer is provided with two symmetrical distribution gaps. a circular ring, and a groove is provided at the vertical notch on one side, and a stepped through hole is provided on the side notch facet of the groove to cooperate with the limit pin, and the two sides of the groove are provided with a through hole and a locating pin Matching; the limit pin is a stepped short shaft. The beneficial effects of Guangdong Yueluo Hardware Industry Co., Ltd. are simple structure, low production cost, convenient and reliable use.
Hex Birminghamcap screw and Hex bolt Hex bolt As the name suggests, it is a male threaded fastener with a hexagonal head, designed to be turned with a wrench. According to the ASME B18.2.1 standard, the head height and shank length tolerance of the hexagon head screw (Hex Birminghamcap screw) is smaller than that of the general large hexagon bolt (Hex bolt), so ASME B18.2.1 hexagon screw is suitable for installation in all hexagon bolts that can be used. places, also including places where the large hex bolts are too large to be used. The screw head of the hexagon socket screw is round on the outside, and the middle is a concave hexagon, and the hexagon screw is the kind of common hexagonal screw head. The hexagon socket head screwdriver looks like a '7'. Cut two sections of a hexagonal steel bar and bend it at 90 degrees to form a hexagon socket head screw wrench, which is sold in hardware tool stores. BirminghamBirminghamHexagon socket screwdrivers are not so-called mobile phone Birminghamspecial screwdrivers. Mobile phone Birminghamspecial screwdrivers can be bought at the booths that sell repair tools in the electronics market. BirminghamBirminghamHexagon socket head Birminghamcap screws are often used in machinery, mainly because they are easy to fasten, disassemble, and not easy to slip. The Allen wrench is generally a 90° bend. One end of the bend is long and one side is short. When using the short side to drive screws, holding the long side can save a lot of force and tighten the screws better. The long end has a round head (a hexagonal cylinder is similar to a sphere) and a flat head. The round head can be easily slanted and disassembled, and some parts that are inconvenient to lower the wrench can be installed. The manufacturing cost of the outer hexagon is much lower than that of the inner hexagon. Its advantages are that the screw head (the force position of the wrench) is thinner than the inner hexagon, and some places cannot be replaced by the inner hexagon. In addition, machines with low cost, low power strength and low precision requirements use much less hexagon socket screws than external hexagon screws. [1] Socket Birminghamcap screw, also known as socket head screw or Allen bolt, is a screw with a hexagonal inner hole on the head, with a hexagonal ruler (hex key, Allen wrench or Allen key) Tighten or loosen only after inserting into the inner hole. The most commonly used hexagon socket head screws are cylindrical head screws with a head diameter of about 1.5 times the main diameter of the thread (1960 series). Countersunk head Birminghamcap screw. The countersunk hole design allows the screw head to be rotated without being exposed on the surface of the fixed object, so it is mostly used in places where the surface is small and it is inconvenient for traditional wrenches to use.
In the modern industrial field, products such as nuts and bolts are widely used to lock structural parts, but at the same time we also find that in many cases, especially when applied to vibration, we often need to lock the already locked Structural parts are regularly repaired and strengthened to prevent structural dislocation caused by loose nuts and bolts.
We have many years of experience in the production and sales of screws, nuts, flat washers, etc. The main products are: bolts, screws and nuts combination sets, white zinc-plated flat washers, plastic insulating screws, countersunk head hexagon socket Birminghamexpansion screws and other products, we can provide You have the right fastener solution for you.
