1. Precision comparison

1. CAM servo turntable adopts no gap meshing between roller and CAM curve surface, reverse

Small clearance, high indexing accuracy and reciprocating positioning accuracy. (The indexing accuracy is generally ±30 seconds, and the repeated positioning accuracy is generally within ±10 seconds).

2. The slewing support is the gear meshing, and the gear meshing should have clearance requirements, so the repeated positioning accuracy error is large when the reciprocating rotation (the general Angle error of the indexing accuracy is more than 6 minutes, 1 minute =60 seconds, and the repeated positioning accuracy is about 1 degree).

Second, the service life comparison

1. The CAM servo turntable is rolling friction when it works, so the friction is small, the precision loss is small, and the service life is long.

2. The gear return support is due to the meshing between the gears and the plane friction, so the wear is large, the precision loss is fast, and the service life is short.

Third, manufacturing time comparison

1. The CAM servo turntable is generally supplied by the manufacturer in a set of ways, and the user can directly assemble the rotating parts on the turntable, shortening the design time and manufacturing time.

2. The use of gear slewing-bearing requires the manufacturer to design a set of gear meshing between the mechanism and the servo motor, which increases the workload of engineers and extends the manufacturing period.
