Parallel Keys, Deep Pattern

A flat key is a key that relies on two sides as working surfaces and transmits torque by extrusion of the key with the side of the keyway. There are three types of plain keys, thin keys, and guided keys. Ordinary type flat key has a good alignment, high positioning accuracy, and convenient folding and loading, but it can't realize the axial fixation of the parts on the shaft, which is used for high speed or the shaft subjected to impact and variable load; the thin flat key is used for the thin-walled structure and transferring torque of a small place; guided flat key is fixed to the shaft with a screw, which is used for the occasions that the parts on the shaft don't move a large amount of movement along the shaft.When the key length is longer than 500mm, its length should be selected according to the R20 series of GB/T 321. In order to minimize the problems caused by straightness, the key length should be less than 10 times the key width.

Flat keys are a common mechanical connection element used to connect rotating shafts and bushings. They are usually made of steel, stainless steel, copper, and other metal materials with high hardness and strength. Flat keys have a right angle, usually rectangular, on one side and a beveled angle on the other side, and are used to fit into the keyway on the shaft and lock the connection between the shaft and the bushing.

Flat keys have the following characteristics:

1. high strength: flat keys are usually made of high-strength metal materials, so they have strong mechanical strength and can withstand great loads and pressures.

2. Stability: Flat keys can provide a stable connection to keep the shaft and sleeve in the correct position to ensure that the machine will not be shifted or messed up during normal operation.

3. Simple structure: Flat key structure is simple, easy to process, low cost, easy to simplify, and design optimization.

4. Easy to install: Flat keys are easy to install, just insert and align them from the keyway, and no special tools or skills are required.

5. Versatility: Since flat keys are widely used in various shaft and bushing interfaces, they are highly versatile and can be used in different models of machines or equipment. The flat key is a small but important mechanical joint with a wide range of applications. It is suitable for many different industries and fields, including machining, manufacturing, automated production, aerospace, etc., and can help designers easily connect and fix rotating parts.
