Description
Technical field
The utility model relates to field of motor manufacturing, and particularly a kind of motor is with the mounting structure of rotary encoder.
Background technology
In common electric machine control, generally adopt rotary encoder to carry out the rate signal collection.Rotary encoder is installed in the anglec of rotation of the axle head collection motor of motor, has rotated what what pulse signals of the corresponding output of dark lattice grooves in rotary encoder inside through its rotor and has calculated rotating speed of motor.But the installation requirement of rotary encoder is accurate, precision is high, and the axle head of machine shaft is directly installed encoder, and rotary encoder is impacted easily and damages, and data are also measured inaccurate.
Summary of the invention
The purpose of the utility model is to provide the mounting structure of a kind of motor with rotary encoder, can make things convenient for the direct installation of rotary encoder, and rotary encoder is not vulnerable to impact, and measurement data is accurate, precision is high.
In order to achieve the above object, the utility model adopts following technical scheme to be achieved.
A kind of motor is with the mounting structure of rotary encoder; Comprise the rotating shaft of motor, be arranged on the bearing in the rotating shaft, be installed in the internal bearing cover and the bearing end cover at bearing two ends; And the rotary encoder that the bearing end cover outside is set; It is characterized in that said bearing end cover inboard is provided with the encoder seat, the encoder seat comprises the fixed disk that is connected the rotating shaft axle head and is arranged on the fixed disk center and stretches out the little axle of transmission of bearing end cover; The little axle of said transmission is through the rotor of shaft coupling connection rotary encoder, and the stator of rotary encoder is fixed on the bearing end cover outside.
The characteristics of the utility model are with further improving:
Said bearing end cover arranged outside has retaining ring, and little axle of transmission and shaft coupling are positioned at retaining ring.
Said bearing end cover arranged outside is useful on the protective cover of rotary encoder.
In the mounting structure of the motor of the utility model with rotary encoder, be provided with the encoder seat in the bearing end cover inboard, the encoder seat comprises the fixed disk that is connected the rotating shaft axle head and is arranged on the fixed disk center and stretches out the little axle of transmission of bearing end cover; Wherein, the little axle of transmission is through the rotor of shaft coupling connection rotary encoder, and the stator of rotary encoder is fixed on the bearing end cover outside.The encoder seat is as the part of motor;, processes by motor when making; Guarantee the concentricity of the little axle of transmission of machine shaft and encoder seat easily; The little axle of transmission can adapt to the installation of dissimilar rotary encoders and avoid rotary encoder to be impacted through the rotor of shaft coupling connection rotary encoder.
In addition, the bearing end cover arranged outside has retaining ring, and little axle of transmission and shaft coupling are positioned at retaining ring, and the bearing end cover arranged outside is useful on the protective cover of rotary encoder, all can improve the degree of protection of motor.
