Backlash Adjustment in Plane Spiroid Gears

Volume 4: Fatigue and Fracture, Heat Transfer, Internal Combustion Engines, Manufacturing, and Technology and Society, 2006
Plane spiroid gears currently applied in feed motion rotary drives are roughly described in this paper. The theoretical possible methods of backlash adjustment in this kind of gear are mentioned. Referring to industry experience the only applied method, which uses the eccentric, is described. Its advantages as well as disadvantages related to operation

Estimation of Gear Backlash: Theory and Simulation

Journal of Dynamic Systems, Measurement, and Control, 1998
Machine and product condition monitoring is important to product quality control, especially for unmanned manufacturing. This paper proposes a technique for the estimation of clearance in mechanical systems under dynamic conditions with specific application to the estimation of backlash in gear systems of servomechanisms.

Parameters Design Platform of Adjustable Gear's Backlash

Applied Mechanics and Materials, 2011
Aiming at the merit and shortcoming of gear's backlash, the paper analyzes several typical gear drivec adjust action regulation. Seeks for the primary factor of influence gear backlash, establish the relationship between the adjustment parameter and the gear's backlash from the gear drive's meshing characteristic, then establishes the parameters design

Gear Train Mesh Efficiency Study: The Effects of an Anti-Backlash Gear

SAE International Journal of Commercial Vehicles, 2014
<div class="section abstract"><div class="htmlview paragraph">In recent years, the focus on engine parasitic losses has increased as a result of the efforts to increase engine efficiency and reduce greenhouse gasses. The engine gear train, used to time the valve system and drive auxiliary loads, contributes to the overall engine parasitic ...

Minimizing angular backlash of a multistage gear train

Proceedings of the Institution of Mechanical Engineers, Part B: Journal of Engineering Manufacture, 2002
An optimization model is constructed to select the optimum reduction ratios that minimize the total angular backlash of a gear train, under constraints on the total reduction ratio and available space. It is found that a proper layout of reduction ratios has a major effect on the total angular backlash of a gear train.

Innovative design of non-backlash worm gear drives

Archives of Civil and Mechanical Engineering, 2018
Abstract In this paper the authors present the newest designs of worm gear drives which allow to adjust or decrease the amount of backlash. This effect is achieved with innovative designs of worms and worm wheels. The designed drives are aimed to find their application in systems for precise positioning of measurement assemblies, precise drives of ...

Dynamics of gear-pair systems with backlash

1999
Dynamics of gear-pair systems involving backlash and time-periodic stiffness is investigated. First, the equation of motion is presented in a strongly nonlinear form, with periodic stiffness and external forcing terms. Then, several types of periodic steady-state response are identified and determined by applying a methodology, that is suitable for ...

The Self-Compensation Approach for Backlash on Gear Pair

Volume 6: Design, Systems, and Complexity, 2021
Abstract The way to properly account for variations in operating center distance and in functional tooth thickness are not obvious. The method presented here will give a good estimate of the range of operating backlash, provided the range of operating center distance and the range of operating functional tooth thickness is known.

Research on gears’ dynamic performance influenced by gear backlash based on fractal theory

Applied Surface Science, 2014
Abstract Gear backlash has an import influence on gear dynamics and due it has a strong non-linear character, so its effect on the gear dynamics is very complex. In order to get reasonable and precise dynamic analytic result, the fractal theory is employed here to express the backlash instead of the existed way of setting backlash as a fixed value or
