Effect of gear design on the power transmission unit of a small-sized multipurpose agricultural utility vehicle

Purpose The purpose of this paper is to examine the impact of organizational justice and conflict management on employee relations (ER) through the mediating role of climate of trust. Design/methodology/approach This study was conducted with a sample of 331 employees working in a power transmission unit of Odisha. Data were collected by administering a structured questionnaire and analyzed using structural equation modeling (AMOS 20). Findings The results reveal that climate of trust plays the role of a partial mediator between organizational justice and ER and conflict management and ER. Also, it was found that organizational justice, conflict management and climate of trust are the positive and significant predictors of ER. Research limitations/implications The study was confined to a single state-owned power transmission unit of an Indian state, which restricts its generalizability. The research would benefit from exploration in alternative units. Practical implications This scholarly work may encourage managers and decision makers to develop trust building climate by focusing on organizational justice and conflict management to flourish an environment of harmonious ER, furthermore to formulate effective strategies for cultivating facilitative work environment to enhance positive attitude among the employees to challenge future goals. Originality/value The research is exclusive in determining the influence of organizational justice and conflict management on ER through the mediator of climate of trust in the new perspective of the power sector that provides empirical evidence to the extant literature.

Standard involute gear designs dominate high-power transmission applications because they combine sufficient bending strength with high pitting resistance, while retaining an adequate contact ratio. In this paper, a non-standard, optimal alternative involute gear design has been presented, which has the same pitting resistance as the standard involute gears but exhibits maximum resistance to bending. The optimization procedure is based on the complex algorithm, where the root stress, as calculated through tabulated boundary element analysis values, is the objective function and the active constraints include all of the kinematical, manufacturing and geometrical conditions, which must be satisfied by the optimal design, including the pitting resistance. The results indicate that optimal designs can achieve up to 8.5 per cent reduction of the fillet stress. Two-dimensional photoelasticity was used to verify the optimization results.

The Given

Conjugate curves have been put forward previously by authors for gear transmission. Compared with traditional conjugate surfaces, the conjugate curves have more flexibility and diversity in aspects of gear design and generation. To further extend its application in power transmission, the geometric and meshing properties of conjugate curves are discussed in this paper. Firstly, general principle descriptions of conjugate curves for arbitrary axial position are introduced. Secondly, geometric analysis of conjugate curves is carried out based on differential geometry including tangent and normal in arbitrary contact direction, characteristic point, and curvature relationships. Then, meshing properties of conjugate curves are further revealed. According to a given plane or spatial curve, the uniqueness of conjugated curve under different contact angle conditions is discussed. Meshing commonality of conjugate curves is also demonstrated in terms of a class of spiral curves contacting in the given direction for various gear axes. Finally, a conclusive summary of this study is given.
