Roots pump mounting/fixing device

Abstract

The invention provides a roots pump mounting / fixing device. The roots pump mounting / fixing device comprises a connecting plate to the middle of which a locking sleeve is connected, and two supporting rods located on two sides of the locking sleeve and detachably connected with the connecting plate, respectively; the bottoms of the supporting rods are fixedly connected with a supporting plate; and a fixing hole matched with a position of a pin hole in a roots pump rotor is further formed in the locking sleeve. The roots pump mounting / fixing device is capable of realizing mounting and fixing work of transmission gears by one person and also capable of synchronously fastening the gears to ensure, in a gear mounting process and between two rotors, stable clearances between the rotors and an inner wall of the roots pump, and in such a manner, air can be removed smoothly and effectively.

Description

technical field [0001] The invention belongs to the technical field of glass deep processing equipment, and in particular relates to a commonly used coating line vacuum pump—a fixing device installed on a gear that drives a rotor to rotate in a Roots pump. Background technique [0002] In the pump chamber, the Roots pump has two "8" shaped rotors installed vertically on a pair of parallel shafts (such as Figure 1-2 As shown), one rotor is directly driven by the drive motor by the connecting shaft, and the other rotor is driven by the gear installed on the Roots pump rotor. A pair of gears with a transmission ratio of 1 drive the opposite synchronous rotation motion to control the rotor to perform reverse synchronous motion. There is a certain gap between the rotors and between the rotor and the inner wall of the pump casing, which can realize high-speed operation. The working principle of the Roots pump is: the rotor rotates continuously, the pumped gas is sucked into the ...

AI Technical Summary

Problems solved by technology

[0004] At present, the installation of Roots pump gear requires two people. By inserting the fixed pin at the driving end of the connecting shaft, the two ends of the pin are grasped by hand, and the force generated during the fastening process of the gear is resisted by manpower. The number of operators requires two people. , and the manpower stability is relatively poor

Because the two rotors are fixed by two gears, and the two gears are mutually driven, it is necessary to fix one gear first, and then fix the other gear according to the distance between the two rotors and the distance between the rotor and the inner wall of the chamber. , once the person who is supporting is not properly supported, it needs to be adjusted again. The reliability of the entire installation process is poor and the efficiency is extremely low
