【Abstract】 Spline gear used in tower cranes is an important part of the transmission which is widely used in the main hoist of tower crane brake institution. In real use, often have the spline gear failure on key slot, if discover the maintenance is not seasonable, easily lead to a major accident. This article through in Pro/E 5.0 environment, with three-dimensional modeling the spline gear of tower crane, and using Pro/ MECHANICA STRUCTURE analysis module to benefit the structural analysis of the spline gear model, and concluded that the key slot on spline gear the reason of failure, and find out the weak part of the spline gear structure, and the optimization of improvement, the reliability of the spline gear significantly increased, so as to ensure that a tower crane in the operation of security.更多还原
