Bearing 309 is socketed on rotating part 3041 and is located in bearing storage space 308a, and the quantity of bearing 309 can be with It is one or more.In the present embodiment, the quantity of bearing 309 is but is not limited to two, and in the axial direction of drive shaft 304 It is arranged side by side, bearing 309 includes outer ring, inner ring and the rolling element being disposed there between, and rolling element can be ball, roller It is to be mounted on bearing block 308 Deng, outer ring, inner ring is mounted in drive shaft 304, is provided with and is socketed between two bearings 309 Bearing spacer sleeve 9 on rotating part 3041 and in bearing storage space 308a, so as to be kept between two bearings 309 default Distance.

In another embodiment, the quantity of bearing 309 is one, then can be not provided with bearing spacer sleeve 9.

In another embodiment, the quantity of bearing 309 is multiple, is provided with bearing spacer between adjacent bearing 309 Set 310.

Referring to Fig. 6 to 8, step structure 308b is respectively formed on bearing block 308, to install the outer of bearing block 308 Circle, in the present embodiment, is respectively formed with step structure 308b corresponding with bearing 309 on the both ends inner wall of bearing block 308, The both ends end face of bearing spacer sleeve 310 is abutted with the end face of the inner ring of two bearings 309 respectively, and bearing spacer sleeve 310 is driving Length dimension in the axial direction of axis 304 is greater than spacing of two step structure 308b in the axial direction of drive shaft 304.

Specifically, bearing block 308 includes the annular protrusion of winding body 3081 and projection on 3081 inner wall of winding body 3082, entire circumferentially extending of the annular protrusion 3082 along winding body 3081, top and the installation base plate 3020 of the winding body 3081 The second face 3022 be connected and fixed, the internal diameter of the winding body 3081 is greater than the aperture of the second pilot hole 3024, annular protrusion 3082 Internal diameter and the second pilot hole 3024 aperture it is identical or essentially identical.The annular protrusion 3082 has the axis in winding body 3081 Two supporting surfaces 3083 relative to each other on line direction, the side towards another 309 inner ring of bearing of the inner ring of bearing 309 Face is connected on supporting surface 3083, and above-mentioned step structure is constituted between winding body 3081 and the end of annular protrusion 3082 308b, that is to say, that length dimension of the bearing spacer sleeve 310 in the axial direction of drive shaft 304 is greater than annular protrusion 3082 and is driving The length dimension of length dimension in the axial direction of moving axis 304, the length dimension of the bearing spacer sleeve 310 and annular protrusion 3082 it Difference in 0.05mm between 0.15mm, preferably 0.1mm.In this way, using the length of bearing spacer sleeve 310 than bearing block 308 two The distance of a step structure 308b will slightly be grown, to guarantee that two bearings 309 will not make the inner ring of bearing 309 by axial direction after mounting Power is excessive or even rolling element is destroyed, to keep drive mechanism more stable.

Referring to Fig. 6 to 8, drive shaft 304 is connected with the discoid driven grinding wheel press cap 311 being located on driven wheel 306, from Driving wheel gland 311 has the inner hole 3111 passed through for interconnecting piece 3042, the inner wall and interconnecting piece 3042 of driven grinding wheel press cap 311 Side wall between be provided with and both make fixed connection structure；The outer diameter of driven grinding wheel press cap 311 is greater than the outer of driven wheel 306 Diameter size.In this way, driven wheel 306 can be pressed in drive shaft 304, by driven grinding wheel press cap 311 to limit driven wheel 306 separate with drive shaft 304, and the outside diameter wall driven wheel 306 of driven grinding wheel press cap 311 is slightly larger, in this way, can facilitate transmission belt 307 Assembly, and after driven grinding wheel press cap 311 is connect with drive shaft 304, it realizes rib function, prevents belt in transmission process from wheel While skidding off, so that the transmission performance of transmission belt 307 is solid and reliable.

Specifically, connection structure includes the threaded portion of the side wall of interconnecting piece 3042 being arranged in, and be arranged in inner hole 3111 Hole wall on and the thread fiting part with threaded portion cooperation, driven grinding wheel press cap 311 is using Screw assembly to drive shaft 304 On interconnecting piece 3042, and compress driven wheel 306.

In another embodiment, driven grinding wheel press cap 311 is connected and fixed by screw with drive shaft 304.

Referring to Fig. 6 to 8, driven wheel 306 has non-circular rotation stop hole 3061, and mounting portion 3043 has and rotation stop hole 3061 The cross-sectional shape that matches of shape, screw can be used between driven wheel 306 and drive shaft 304 and be connected and fixed.In this implementation In example, rotation stop hole 3061 is but is not limited to waist-shaped hole, and mounting portion 3043 has the cross to match with the shape in rotation stop hole 3061 Cross sectional shape, in such manner, it is possible to be convenient for the dismounting of driven wheel 306 and drive shaft 304,304 power transmission of drive shaft after assembly is more Add stabilization, avoid using screw connection when, because screw bears excessive torsion cause screw easily loosens even drop out show As occurring.

From Fig. 6 to 8 as can be seen that projection formation limiting section 3062, limit on 3061 inner wall of rotation stop hole of driven wheel 306 Portion 3062 is formed with the recess portion 3045 of annular on the side wall of mounting portion 3043, in driven wheel along the circumferentially extending of driven wheel 306 306 with drive shaft 304 assemble when, with limiting section 3062 cooperate limit, so that it is opposite with drive shaft 304 to limit driven wheel 306 It is mobile.

Referring to Fig. 6 to 8, the driving mechanism 300 of the present embodiment further includes detection device, to detect turning for drive shaft 304 Dynamic angle.In the present embodiment, detection device includes Magnetic testi bracket 315, magnetic encoder 313, magnetic orientation pedestal 314 and magnetic Iron 312, Magnetic testi bracket 315 are fixedly connected on bearing block 308 using all existing fixed forms such as screw, welding, and A detection space is defined jointly with bearing block 308；Magnetic encoder 313 is fixed on Magnetic testi bracket 315, magnetic encoder 313 include Magnetic Sensor, which is but is not limited to Hall sensor；Magnetic orientation pedestal 314 uses screw, welding etc. All existing fixed forms, which are fixed on, to be connected on rotating part 3041 and is located in detection space, and magnet 312 is fixed at On magnetic orientation pedestal 314；The center of magnetic encoder 313 and the center of magnet 312 are respectively positioned on the extension of the axis of drive shaft 304 On line.Magnetic encoder 313 and above-mentioned control circuit board 110 are electrically connected, and magnetic encoder 313 is because pass through Magnetic testi branch Frame 315 is connected with bearing block 308, be it is fixed, magnet 312 is connected by magnetic orientation pedestal 314 with drive shaft 304, is It is rotated together with driven wheel 306, therefore, opposite rotation can have occurred when rotating rotation for magnetic encoder 313 and magnet 312 Turn, control circuit board 110 can detect the rotational angle of driven wheel 306 from magnetic encoder 313, and to drive shaft 304 Movement angle is controlled.

In another embodiment, detection device also may include Photo Interrupter (also referred to as penetrating type photoelectric sensor), the light Breaker includes luminescence component and photosensory assembly, can open up loophole in drive shaft 304, using shading principle to realize detection function Energy.

The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this Made any modification, equivalent replacement or improvement etc., should be included in the utility model within the spirit and principle of utility model Protection scope within.
