Abstract

The invention discloses a novel two-end rotor of a single-stage roots blower. The novel two-end rotor comprises a rotor shaft (1), and a first rotor (2) and a second rotor (4) which are arranged on the rotor shaft (1) and is characterized in that a first rotor bus (3) of the first rotor (2) and a second rotor bus (5) of the second rotor (4) are not positioned on the same straight line. The buses of the conventional two-end rotor are positioned on the same straight line; and the buses of the novel two-end rotor of the single-stage roots blower are staggered from each other at a certain angle. By the novel two-end rotor of the single-stage roots blower, air flow is more steady, and air flow pulse of the single-stage roots blower can be effectively reduced.

Description

The novel two ends rotor of single-stage roots blower
Technical field
The present invention relates to the roots blower field, especially a kind of 2 segmentation roots blower rotor structures.
Background technique
Such as Fig. 1, roots blower is the positive displacement blower fan, air quantity and the revolution carried are proportional, reach between impeller end face and the blower fan front and rear cover that the person remains small gap between the draught fan impeller, are transported to a side of discharge from air inlet along inner walls in the drive leeward of synchromesh gear.
Summary of the invention
The object of the present invention is to provide a kind of 2 segmentation roots blower rotor structures, to overcome defects.
Technological scheme of the present invention is:
A kind of 2 segmentation roots blower rotor structures comprise rotor shaft 1, are arranged on the first rotor 2 and the second rotor 4 on the rotor shaft 1, and the second rotor bus 5 of the first rotor bus 3 of described the first rotor 2 and the second rotor 4 is not on same straight line.
Angle between the second rotor bus 5 of the first rotor bus 3 of described the first rotor 2 and the second rotor 4 is that 10 degree are to 45 degree.Be preferably 30 degree.
The invention has the beneficial effects as follows:
The bus of tradition two ends molded lines of rotor on same straight line, the bus of 2 segmentation roots blower rotor structures of the present invention certain angle that staggers.
Adopt 2 segmentation roots blower rotor structures of the present invention, air-flow is more steady, can effectively reduce the gas of whole blower.
Description of drawings
Fig. 1 is the structural representation of traditional roots blower rotor.
Fig. 2 is the structural representation of roots blower rotor of the present invention.
Among the figure: 1 is that rotor shaft, 2 is that the first rotor, 3 is that the first rotor bus, 4 is that the second rotor, 5 is the second rotor bus.
Embodiment
The invention will be further described below in conjunction with accompanying drawing:
Such as Fig. 2, a kind of 2 segmentation roots blower rotor structures comprise rotor shaft 1, are arranged on the first rotor 2 and the second rotor 4 on the rotor shaft 1, and the second rotor bus 5 of the first rotor bus 3 of described the first rotor 2 and the second rotor 4 is not on same straight line.
Angle between the second rotor bus 5 of the first rotor bus 3 of the first rotor 2 and the second rotor 4 is that 10 degree are to 45 degree.Be preferably 30 degree.
Embodiment recited above is described preferred implementation of the present invention; be not that the spirit and scope of the present invention are limited; do not breaking away under the design concept prerequisite of the present invention; common engineers and technicians make technological scheme of the present invention in related domain various modification and improvement; all should fall into protection scope of the present invention, the technology contents that the present invention asks for protection all is documented in claims.

Claims (2)

1. segmentation roots blower rotor structure, comprise rotor shaft (1), be arranged on the first rotor (2) and the second rotor (4) on the rotor shaft (1), it is characterized in that the second rotor bus (5) of the first rotor bus (3) of described the first rotor (2) and the second rotor (4) is not on same straight line.
2. 2 segmentation roots blower rotor structures according to claim 1 is characterized in that the angle between the second rotor bus (5) of the first rotor bus (3) of described the first rotor (2) and the second rotor (4) is that 10 degree are to 45 degree.Be preferably 30 degree.
