Abstract

The utility model discloses a common base bi-rotor two-speed motor which comprises a shell base, stators fixed on the inner wall of a shell, rotors contained in inner rings of the stators, end coversfixed at the two axial ends of the shell and a rotary shaft fixed with the rotors; the outer end of the rotary shaft is fixed with the end cover by a bearing; the axial middle of the shell of the shell base is provided with a separating part; two groups of stators at the two axial sides of the separating part are mutually independent; the rotors comprise two independent rotors respectively arranged in the inner rings of the two groups of stators; the center of the two ends of the separating part is embedded and fixed with the bearing; and the rotary shaft at the inner ends of the rotors is fixed with the separating part by the bearing. The common base bi-rotor two-speed motor can output different rotating speeds on output shafts at the two ends of the base, meet the requirement of users onusing two rotating mechanisms at different rotating speeds simultaneously, bring convenience to the users and save cost.

Description

Cobasis seat birotor double-speed motor

Technical field

The utility model relates to a kind of cobasis seat birotor double-speed motor, relates in particular to the employed cobasis seat of a kind of centrifugal spraying spraying machine birotor double-speed motor.

Background technology

In the prior art, common motor generally all only is made of a stator and a rotor, and when stator was fixed on the housing pedestal, rotor can rotate in stator during work, and should rotate by epitrochanterian output shaft and be transferred to other mechanism.The motor of said structure can only be exported a kind of rotating speed at one time, when having two mechanisms to turn round with different rotating speeds simultaneously, just needs to be equipped with two independent motors and gives two rotating mechanism transmissions respectively.

Summary of the invention

The utility model purpose provides a kind of cobasis seat birotor double-speed motor, it can export different rotating speeds respectively on the output shaft at pedestal two ends, satisfy the needs that the user uses two rotating mechanism different rotating speeds simultaneously, provide convenience, saved cost to the user.

The technical solution of the utility model is: a kind of cobasis seat birotor double-speed motor, comprise package header, be fixed in the stator of inner walls, be placed in the rotor of stator inner ring, be fixed in housing shaft to the end cap at two ends and the rotation axis of fixing with rotor, the outer end of described rotation axis is fixed by bearing and end cap, described package header housing shaft is provided with separating part to the middle part, two groups of stators of the axial both sides of described separating part are separate, described rotor comprises two separate rotors that lay respectively at two groups of stator inner rings, the center at described separating part two ends is embedded and is fixed with bearing, and the rotation axis of described rotor the inner is fixed by bearing and separating part.

The two pairs of stators and rotor in the package header are separate, and its parameter can differently be provided with, and so just makes two rotors can export different rotating speeds.

The utility model advantage is:

1. the utility model is provided with two pairs of stator and rotors that parameter is different respectively in same pedestal, make the output shaft at the axial two ends of pedestal the same time to distinguish outputting two rotating speeds, replace and to need two independent motors being equipped with in the past, provide convenience, saved cost to the user.

Embodiment

Below in conjunction with drawings and Examples the utility model is further described:

Embodiment: shown in Fig. 1 to 4, a kind of cobasis seat birotor double-speed motor, comprise package header 1, be fixed in the stator 2 of inner walls, be placed in the rotor 3 of stator 2 inner rings, be fixed in housing shaft to the end cap 5 at two ends and the rotation axis of fixing with rotor 34, the outer end of described rotation axis 4 is fixing with end cap 5 by bearing 7, described package header 1 housing shaft is provided with separating part 6 to the middle part, two groups of stators 2 of described separating part 6 axial both sides are separate, described rotor 3 comprises two separate rotors 3 that lay respectively at two groups of stator 2 inner rings, the center at described separating part 6 two ends is embedded and is fixed with bearing 8, and the rotation axis 4 of described rotor 3 the inners is fixing with separating part 6 by bearing 8.

Between described two pairs of stators 2 and the rotor 3 is separate, and its parameter setting can be different, as different motor number of pole-pairs etc. is set, and makes in use, and the every pair of stator 2 and rotor 3 cooperate the output different rotating speeds.

Present embodiment is applied to the power drive of centrifugal spraying spraying machine, and an end output speed of motor rotation axis is 2800 rev/mins, connects the atomizing disk assembly; Other end output speed is 1400 rev/mins, connects the fan blade assembly; Adjust mist flow, throw wind speed, the carry of spray and the fogdrop diameter of spraying machine by the rotating speed of regulating the two ends rotation axis, thereby reach desirable atomizing effect.

The utility model can be exported different rotating speeds respectively on the output shaft at pedestal two ends, satisfy the needs that the user uses two rotating mechanism different rotating speeds simultaneously, provides convenience to the user, has saved cost.
