Application of Gear Rack And Pinion
The working principle of pinion and rack is to convert the rotary motion of the gear into the reciprocating linear motion of the rack, or the reciprocating linear motion of the rack into the rotary motion of the gear. Suitable for fast and accurate positioning mechanism, suitable for heavy load, high precision, high rigidity, high speed and long stroke CNC machine tools, machining centers, cutting machinery, welding machinery, etc., suitable for factory automation fast transplanting machinery, industrial robot arm grasp mechanism, etc.
Features of Gear Rack And Pinion
Rack has the following characteristics:
1) The tooth profile on the same side of the rack is a parallel line, and it has the same tooth distance on any line parallel to the fixed line of the tooth.
2) Each point on the linear tooth profile of the rack has the same pressure Angle, which is equal to the tooth profile Angle of the linear tooth profile, which is generally the standard value;
When the rack and pinion is installed standard, the dividing circle of the gear coincides with the dividing line of the rack, and the meshing Angle is equal to the tooth shape Angle. The gears turn at an angular speed,
Drive the rack to move in a straight line with linear speed.
Center distance increases, away from the axis of the gear rack 01 mobile X distance) (below the dotted line, according to the characteristics of the rack straight tooth profile and meshing line will not change, change with rack position so the node position P does not change, at this point, the gear of dividing circle still coincide with the pitch circle, meshing Angle is equal to the rack tooth profile Angle, which is equal to the pressure Angle of gear indexing disk; However, the change of rack position makes the midline and nodal line of the rack no longer coincide, and the tooth side gap j increases, and the top gap increases. Namely: rack and pinion positive displacement transmission,
