GEARBOX

摘要

A gearbox comprises an input shaft, an input shaft bearing, an output shaft bearing (9, 10), a box body (1), and an output shaft (2). The input shaft is supported on the box body (1) through the input shaft bearing. The gearbox further comprises a detachable sub-box body (3) disposed on the box body (1). The output shaft (2) is supported in the sub-box body (3) through the output shaft bearing (9, 10). The output shaft (2) realizes power transmission with the input shaft through a gear on the output shaft. The output shaft (2) is mounted in the sub-box body (3), so that the sub-box body (3) is connected to the box body (1) in a detachable manner. By detaching the sub-box body (3) from the box body (1), the output shaft (2) can be removed and replaced easily and conveniently, thereby facilitating the repair of the gearbox and reducing the repair costs.
