Description

A motor flange that is easy to install and fasten

technical field

The utility model relates to the field of flanges, in particular to a motor flange which is convenient for installation and fastening.

Background technique

Flange is otherwise known as flange flange or flange. Flanges are parts that are connected to each other between pipes and are used for connection between pipe ends; they are also useful for flanges on equipment inlets and outlets, And can be used as connection between two equipments, example reducer flanges. Flange connection or flange joint refers back to the detachable connection of flange, Gasket and bolt as a team of combined sealing structure. Pipe flange refers back to the flange used for piping in the pipeline installation, And used on the equipment refers to the inlet and outlet flange of the equipment. There are holes in the flange, and the bolts tightly connect the two flanges. The flanges are sealed with gaskets. Flanges are divided into threaded (screw connection) flanges, welding flanges and clip flanges. Flanges are usually employed in pairs, very poor-work pipes can use wire flanges and welding flanges with pressures greater than 4 kg. Add sealing points within the two flanges, immediately after tighten with bolts. Flanges with different pressures have different thicknesses, and the bolts they use are also different. When the water pump and valve are connected to the pipeline, some parts of these equipments are also made into corresponding flange shapes, also called flange connection. All connecting parts that are closed at the same time by using bolts around the two planes are generally called "flanges". For example, the connection of ventilation pipes, such parts can be called "flange parts". But this connection is only a part of the equipment, Such as the text between the flange and the pump, it is not easy to call the pump 'flange parts'. Smaller ones such like valves Wait, always be called 'flange parts'.

When producing and installing motor flange parts, motors of different sizes and models need to be adapted to flanges of different weights. The larger the motor shaft, the heavier the flange installed, and it is not easy to install and fasten, resulting in time-consuming and labor-intensive work for the staff. A solution to the above problems is proposed below.

Preferably, the sealing collar divides the limiting ring and the flange body into a fastening area and a limiting area.

Preferably, the diameter of the through screw hole is larger than that of the screw hole.

Preferably, the top end surface of the ear is smaller than the top end surface of the chime.

Preferably, the mounting frame is triangular in shape.

Preferably, a placement groove is opened in the through screw hole on the back of the flange body.

Beneficial effects: when installing the motor flange body on the motor shaft, it is more convenient for the staff to install the flange body in place through the convex edge and side ears, and the position of the flange body can be quickly aligned and installed by holding the convex edge. The sides and side lugs can play a good role in positioning, and speed up the efficiency of workers installing motor flanges in batches.
