Abstract
The utility model discloses a mounting structure of a three-phase asynchronous motor speed sensor. A shaft housing is arranged on a motor shaft. The shaft housing is fixedly connected with the motor shaft. A gear sleeve mounting hole is arranged on the shaft housing, and a gear sleeve is fixed on the shaft housing. The mounting structure of the three-phase asynchronous motor speed sensor has the advantage that the speed sensor can be flexibly mounted to adapt to different motor design requirements.
Description
Technical field
The utility model belongs to traction and makes the field with Flame-Proof Three-Phase Induction Motors, is a kind of mounting structure of asynchronous motor velocity transducer specifically.
Background technology
Detection and rotor speed by motor stator, rotor relative position relation, turn to the detection with instantaneous position, can realize the controls such as motor operation, running under braking, conversion direction, and can change automatically adjustment output torque according to load torque, and rotating speed is constant.
Common tachogenerator generally is installed in the rear end of axle, generally comprises axially and radially install pattern, and concrete structure is seen Fig. 1 and Fig. 2.In these two kinds of patterns, sensor probe and geared sleeve are installed all than being easier to.But for the motor shaft that needs the mounted motor brake, for the consideration of intensity aspect, the rear end diameter of axle of motor can not be too small, and the installation that is enclosed within on the axle for sensor gear has like this caused difficulty indirectly.
The utility model content
In order to solve the problems of the technologies described above, the purpose of this utility model provides a kind of mounting structure that can be installed in flexibly the transducer of the relevant position on the axle, and concrete scheme is:
A kind of mounting structure of threephase asynchronous velocity transducer arranges an axle sleeve at motor shaft, and described axle sleeve and motor shaft are for being fixedly connected with; The geared sleeve installing hole is set on the described axle sleeve, and geared sleeve is fixed on the axle sleeve.
Described installing hole is screw.
The utility model has the advantages that: can accomplish that the flexible installation of tachogenerator is to adapt to different design of electrical motor requirements.
Description of drawings
Fig. 1 is axial mounting structure schematic diagram;
Fig. 2 is mounting structure schematic diagram radially;
Fig. 3 is the utility model structural representation;
Among the figure, 1 is motor shaft, and 2 is sensor probe, and 3 is sensor stand, and 4 is geared sleeve, and 5 is axle sleeve.
Embodiment
Specify the utility model below in conjunction with accompanying drawing, as shown in Figure 3, in the present embodiment, the installation site of transducer is in the posterior segment of motor shaft, and the mounted motor brake is also wanted in its rear end.Because the installation of brake, in order to solve this difficulty, the utility model arranges a thinner axle sleeve 5 at motor shaft 1, and before installation on axle sleeve 5 in advance machining gears overlap 4 installation screws.Axle sleeve 5 and motor shaft 1 are for being fixedly connected with; Geared sleeve 4 is fixed on the axle sleeve 5.
Claims (2)
1. the mounting structure of a threephase asynchronous velocity transducer is characterized in that: at motor shaft an axle sleeve is set, described axle sleeve and motor shaft are for being fixedly connected with; The geared sleeve installing hole is set on the described axle sleeve, and geared sleeve is fixed on the axle sleeve.
2. structure according to claim 1, it is characterized in that: described installing hole is screw.
