The slotted nut needs to be fixed with a cotter pin through the slot of the slotted nut, and the cotter pin must pass through the middle of the screw to fix the slotted nut. Usually, both ends of the screw need to be drilled, the diameter of the hole and the size of the slotted nut. The width and depth of the slot determine the size of the cotter pin. When the selected screw, cotter pin and slotted nut are relatively matched, the nut is fixed by the screw, so that the slotted nut does not loosen. This hexagonal slotted nut has the characteristics of high strength and is not easy to loosen when subjected to vibration. It is mainly used in occasions with vibration and shock, such as front and rear axles of automobiles, lifting equipment, presses and die-casting machines.
shaft retaining ring installation tool and an installation method thereof relate to an assembly tool and an installation method thereof, comprising a pressing cylinder and a taper sleeve. The maximum diameter of the tapered end is slightly smaller than the inner diameter of the circular straight hole of the pressing cylinder, and the lower end of the tapered sleeve has a positioning structure matched with the shaft of the shaft retaining ring to be installed. The method includes the following: place the taper sleeve on one end of the shaft where the shaft retaining ring is to be installed and position it well, then place the shaft retaining ring on the tapered end of the taper sleeve, and finally press down the pressure cylinder to make the shaft Use the retaining ring to slide down the conical surface of the taper sleeve to the shaft to be installed with the retaining ring for the shaft, and finally get stuck in the groove of the shaft. Yueluo does not need to open the retaining ring for the shaft, which reduces the operation force and labor intensity. The operation method is simple, the structure is simple and reliable, the cost is low, and it is easy to popularize and use.
The flat key is a key that relies on the two sides as the working surface and transmits the torque by the extrusion of the key and the side of the keyway, and is mostly installed on the shaft. If the flat key is used for a long time or is in a bad working environment for a long time, dust, oil, etc. will inevitably be stuck between the flat key and the keyway. Since the flat key has no ejector threaded hole for disassembly, it is difficult to dismantle, and during the disassembly process A little carelessness will cause damage to the flat key.
Supporting T-bolts for pre-embedded channels, including hot-rolled pre-embedded channels, the lower part of the pre-embedded channel is provided with a longitudinal opening, and the head of the T-bolt enters from the opening and is clamped in the pre-embedded channel. There are plane teeth at the connection between the buried channel and the T-bolt, and the T-bolt has a tooth-shaped structure matched with the plane teeth. The direction of the teeth is parallel to the slotting direction, and the tooth-shaped cooperation achieves anti-slip effect. However, when the nut tightened on the T-bolt becomes loose, it will cause the T-bolt to move into the embedded channel and lose the toothed fit, thus changing the fixed position of the T-bolt in the embedded channel.
The pin, also known as the pin, has a simple structure and is easy to assemble and disassemble. It is widely used in various fixed connections. The pin is mainly used to fix the relative position between two parts, also used to connect parts, and can transmit a certain load. , At present, the pins on the market generally have the problems of being easy to loosen and fall off.
