19 tooth single-groove double-bore semi-circular bottom gear

Although standard cylindrical Gear transmission has the advantages of simple design and good interchangeability, it also has some shortcomings, such as
When the number of lost teeth is less than a certain number of teeth, root cutting will occur, and the actual center distance is not equal to the standard center distance of the dry trunk
Method installation or side follower is too large, the bearing capacity and life difference of large and small gears in a pair of meshing gears are large. head
In order to improve the above deficiencies of standard gears, necessary modifications must be made to standard gears, which are currently the most widely used
It is the conjugation correction method. Gear displacement is achieved by changing the relative position of the gear machining tool and the wheel break, the tool is far from the wheel damage center, and the processed gear is a positive shift gear. Conversely, if the cutter approaches the center of the wheel break, add
T's gear is a negative shift gear. Compared with standard gears, the indexing circle, base circle and tooth pitch of the variable strike wheel are not the same
However, the tooth thickness, cogging width, working section of the tooth profile curve, tooth top height, tooth root height, etc. have changed. The degree of gear displacement correction depends on the displacement coefficient, if the displacement coefficient of both meshing gears is zero, it is standard gear transmission; If the deflection coefficients of the two gears are opposite and the magnitude is equal, it is an isostatically variable gear transmission; If the sum of the displacement coefficients of the two gears is not equal to zero, it is an unequal gear transmission. The gradual opening is manufactured by the conjugation correction method
Line cylindrical gear, not only can avoid the root cutting phenomenon, but also can match the center distance, improve the bearing capacity of the gear pair and reduce the structural size of the mechanism, and will not increase the difficulty of processing and manufacturing, so the variable gear transmission has been widely used in various machinery.

In addition, we have other accessories such as Circular machine oiler, Control Panel, Adjustable Yarn Bobbin Cover, Synchronous Belt, Needle Cylinder and so on.
