What are the components of the carbide saw blade gear grinding machine that make up the gear?
 
 
 
(1) Passing motion accuracy We require that the gear can transmit motion more accurately and keep the gear ratio constant. That is, the angular error of the gear in one revolution is required to be smaller than a certain range.
 
(2) Transfer of motion stability
 
We require gears to move smoothly to reduce shock, vibration and noise. That is, it is required to limit the change of the instantaneous speed ratio when the gear rotates.
 
(3) Load distribution uniformity
 
When we require the gear to be made, the teeth should be evenly contacted so that the gear does not cause uneven contact due to uneven load distribution when transmitting power, causing premature wear of the tooth surface. In addition to the uniformity of the tooth surface contact, the contact accuracy includes the contact and the contact position.
 
(4) Rationality of transmission backlash
 
When we require the gear to be made, there is a certain gap between the non-working tooth surfaces to store the lubricating oil, to compensate for dimensional changes caused by temperature and elastic deformation, and some errors in assembly and assembly.
 
Since the manufacturing precision of the gear and the flank clearance are mainly determined according to the use of the gear and the conditions of the upper gear. In practical application: for the gears for indexing transmission, the movement precision of the gears is mainly required; for the gears for high-speed power transmission, in order to reduce the impact and noise, there is a high requirement for the smoothness of the upper; for heavy-duty low speed Gears for transmissions require higher contact accuracy of the tooth surface of the gear grinding machine to ensure that the gears do not wear prematurely; for gears for the reversing drive and reading mechanism, the tooth side clearance should be strictly controlled, if necessary, The gap must be eliminated.
 
 
Carbide saw blade grinding machine consists of the following parts:
 
(1) Bed. The support parts of the machine tool, the rigidity of the machine tool and the joint accuracy between the parts are mainly guaranteed by the bed;
 
(2) z-direction CNC slide table. Mounted on the column and reciprocated parallel to the gear axis;
 
(3) Grinding wheel frame. Installed on the z-direction slide table, the grinding wheel frame can drive the entire grinding head and the moving plate of the indexing mechanism to rotate the indexing of the fixed disk to grind the helical gear. The grinding head is driven by an electric motor, and the grinding wheel is rotated at a high speed through a belt;
 
(4) Grinding wheel dressing device. The grinding wheel dressing device performs the involute interpolation by the linkage of the x slide table and the y slide table, and trims the end surface of the grinding wheel into the same involute shape as the tooth profile of the workpiece;
 
(5) C-direction CNC rotary table. Drive the gear to turn over the indexing angle until all the teeth are finished;
 
(6) X-direction CNC slide table. The workpiece table is moved horizontally, and the machine tool is adjusted in the x direction to control the tooth thickness and the tooth angle. When the grinding wheel needs to be trimmed, the dressing device is brought closer to the grinding wheel;
 
(7) l, to the mechanical slide. The column is moved in the direction of l, used to adjust the machine parameters, and the inner and outer gears of different diameters are processed.
