Bookmark or Share- Gear Drive - an overview | ScienceDirect TopicsAn increase of bearing capacity of the gear drive is the goal of the gear drive of novel design composed of gears with the surface hardness of the tooth flanks ≤400HB. The gear drive ( Fig. 2.45 ) is comprised of two gears 1 and 2 having tooth profiles feature involute portion 3, that intersects the pitch line, and two off-pitch-point ...
- Design principle and numerical analysis for cycloidal drive considering ...Cycloidal drives are essentially specialized planetary transmissions that utilize a pin gear as the internal gear, cycloidal gears as the planetary gears, and a planetary carrier in the form of an eccentric shaft as the power input. Various studies have derived the ideal cycloidal gear tooth profile equation using different methods [11], [12 ...
- Computerized design, generation and simulation of meshing and contact ...In case of conventional design of a worm-gear drive, the hob for generation of worm-gear is identical to the worm of the gear drive. Such an approach must be avoided because errors of alignment will cause edge contact on worm-gear tooth surface and transmission errors of unfavorable shape and impermissible magnitude [4], [6].
- Design, simulation of meshing, and contact stresses for an improved ...A modified worm gear drive of Klingelnberg type is considered initially. The worm-gear is generated by an oversized hob with Δr = 2 mm, but parabola coefficient a t of generating disk of the hob is considered zero. The basic gear drive data are shown in Table 1. Fig. 6 shows the results from TCA
- Study on the vibration characteristics of worm helical gear driveSince the worm helical gear drive is a point-contact transmission form, with no specific contact line between its teeth, tooth profile modification is mainly employed to improve the drive. Due to manufacturing inaccuracies that occur during production, the actual tooth profile deviates from the ideal form and becomes an arbitrary curve on the ...
