Problems solved by technology

[0002] The quenching coil of the traditional vacuum pump rotor is circular, and the head of the entire vacuum pump rotor is completely quenched. The disadvantage is that it is not easy to quench the root of the cross groove of the vacuum pump rotor, so that the product is not wear-resistant, and it is easy to quench the center hole, resulting in cracks

Embodiment Construction

[0011] A vacuum pump rotor quenching coil. The quenching coil is connected to a base 1. The quenching coil is bent from a square pure copper tube into two symmetrical U-shaped coil heads 2. The two U A conductor magnet 3 is uniformly bonded in the font-shaped coil head 2 respectively, and a conductor magnet 3 is evenly bonded between the two U-shaped coil heads 2 and the two U-shaped coil heads 2 Keep it level, the verticality between the two U-shaped coil heads 2 and the base 1 is 0.1-0.2max.

[0012] The thickness of the square pure copper tube is 4.5-5.5mm, the width of the U-shaped coil head 2 is 7-9mm, the length of the magnet 3 is 8-10mm, the width is 5-7mm, and the height is 10-15mm. .

[0013] The end surface of the magnetic conductor 3 is lower than the end surface of the U-shaped coil head 2 by 1-2 mm.

Abstract

The invention relates to a quenching coil for the rotor of a vacuum pump. The quenching coil is arranged on and connected with a base and is composed of two symmetrical U-shaped coil heads formed by bending a square pure copper pipe, wherein a magnetizer is arranged in and uniformly bonded with each of the two U-shaped coil heads; another magnetizer is arranged between and uniformly bonded with the two U-shaped coil heads; the two U-shaped coil heads are maintained horizontal; and the perpendicularity of the two U-shaped coil heads to the base is 0.1-0.2 max. Compared with conventional circular coils which carry out complete quenching on the whole heads and have the disadvantages of easy incurrence of cracks and hard quenching of the roots of cross recesses, the quenching coil of the invention is improved, can carry out quenching inside the cross recess of the vacuum pump rotor and achieves magnetic field-shielding effect in virtue of the magnetizers, thereby avoiding small hole cracksdue to quenching to middle small holes in products.

Description

Technical field [0001] The invention relates to a vacuum pump rotor coil, in particular to a vacuum pump rotor quenching coil. Background technique [0002] The quenching coil of the traditional vacuum pump rotor is round, and the head of the entire vacuum pump rotor is completely quenched. The disadvantage is that it is not easy to be quenched to the root of the vacuum pump rotor cross groove, which makes the product not wear-resistant, and is easy to be quenched to the center hole, causing cracks. Summary of the invention [0003] In order to solve the above problems, the invention provides a vacuum pump rotor quenching coil with simple structure, improved rotor wear resistance, no cracks in the rotor center hole, fully quenched rotor cross groove, convenient processing and long service life. [0004] The technical solution of the present invention is: the quenching coil is connected to the base, the quenching coil is bent from a square pure copper tube into two symmetrical U-shap...
