Problems solved by technology

[0002] The forged flange has accurate blank shape and size, small processing amount, and low cost, but has casting defects (pores, cracks, inclusions); the internal structure of the casting is poorly streamlined; at present, a small number of inferior flange castings are cast, and the dimensional accuracy is required Higher small castings can be used for special casting, such as permanent casting, precision casting, pressure casting, investment casting, etc.
The disadvantage is that this type of flange is prone to leakage during use, so forged flanges are generally used now. Since continuous and uniform metal fiber structures can be obtained after forging, the mechanical properties of this type of flange are guaranteed to be better. Commonly used in environments with complex forces
[0003] When the connecting flange is in use, it is necessary to fix the two shafts. It is forbidden to slip and fall off when the transmission is connected. Generally, the shaft and the flange will not fall off on the shaft, but it is easy to slip in the radial direction. The shafts at both ends of the flange cannot accurately transmit speed and torque

Embodiment Construction

[0019] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0020] see figure 1 , a connection flange according to a preferred embodiment of the present invention, including a connection flange, including a flange 1, the left and right sides of the flange 1 are respectively provided with a left boss 2 and a right boss 3. The left boss 2 and the right boss 3 are respectively provided with a large shaft installation hole for installing the large shaft 4 and a small shaft installation hole for installing the small shaft, which is characterized in that: the left boss 2 is large A plurality of convex grooves 3 are arranged in the shaft mounting hole.

[0021] - The number of the convex grooves 3 is four, which are evenly spaced on the...

Abstract

The invention relates to a connecting flange which comprises a flange plate (1). A left boss (2) and a right boss (3) are arranged on the left side and the right side of the flange plate (1) correspondingly. A large shaft installation hole used for installing a large shaft (4) is formed in the left boss (2), and a small shaft installation hole used for installing a small shaft is formed in the right boss (3). Multiple protruding grooves (31) are formed in the large shaft installation hole of the left boss (2). It is ensured that the friction force of the large shaft and the end face of the large shaft installation hole is large enough through a concave groove in the large shaft and the protruding grooves in the large shaft installation hole, and therefore radial sliding of the large shaft in the large shaft installation hole can be prevented.
