Between dc motor and spindle components adopt synchronous belt transmission, due to the use of dc motor speed at 20 v speed can reach 15000 r/min, so the choice of transmission ratio is 1, CNC woodworking engraving machine spindle component structure as shown in the figure below.
Dc motor output torque through the synchronous belt is passed to the output shaft, reduces the performance of dc motor speed and precision requirements, at the same time also can partition the motor vibration transfer and overload protection.
Due to the angular contact bearings to count more than deep groove ball bearings, the rated load in the ball bearing is the largest, strong rigidity, smooth operation, angular contact bearings can bear radial load and axial load at the same time, high speed, the greater the contact Angle, the higher the axial bearing capacity.
Due to the single bearing can only carry axial load in one direction, when bear radial load, will cause the additional axial force, and can only limit shaft or shell axial displacement in one direction.
If double installed in pairs, can avoid the additional axial force, and can make the shaft in two direction or shell limits in the range of the axial clearance.
CNC woodworking engraving machine spindle component structure of the CNC woodworking engraving machine carved error depends mainly on carving the radial and axial runout of spindle component, in order to reduce the error, take the following methods:
1, choose a pair of 25 at the end of the output shaft & deg; Angular contact bearing to bear the axial and radial load of output shaft, pairs of bearing to avoid additional axial force, ensure the accuracy of the output shaft axis, but also improve the rotary accuracy of cutting tool.
2, with the top of the output shaft adopt deep groove ball bearing support, distance gland have certain gap, ensures axis high-speed heating has the certain scale space, avoid expansion deformation of shaft.
3, the output shaft end USES the taper hole honing guarantee and ER11 cutter holder to cooperate; The fixed end of the shaft to the length of the cutting tool is short as far as possible; The two measures can reduce the axial radial runout.
4, internal space of the shaft is up and down with a sealing ring gland seal, prevent dust and crumbs carved into the internal wear components, improve the service life and accuracy.
