Abstract

The invention provides a speed reducer output shaft lengthening device which comprises a speed reducer output shaft 1, a transmission belt pulley 6 fixed to the outer side of the speed reducer output shaft 1 through a flat key 2, and a lengthening structure located on the lower face of the speed reducer output shaft 1. The lengthening structure comprises a lengthening shaft 4, two deep groove ball bearings 3 arranged outside the lengthening shaft 4 in a sleeved mode, and a sleeve 5 arranged outside the lengthening shaft 4 in a sleeved mode and located between the two deep groove ball bearings 3. The two ends of the sleeve 5 abut against the inner circles of the deep groove ball bearings 3. The lengthening structure is fixed into the lower portion of the transmission belt pulley 6 through the outer circles of the deep groove ball bearings 3. A cylindrical speed reducer support 7 is arranged outside the transmission belt pulley 6 and connected with the lower end of the lengthening shaft 4. The lengthening structure composed of the lengthening shaft 4, the sleeve 5 and the deep groove ball bearings 3 is added, and therefore the length of the speed reducer output shaft 1 is increased, the actual use requirements are met, and high cost for special customization is saved.

Description

technical field [0001] The invention relates to a lengthening device for a mechanical transmission system, in particular to a lengthening device for an output shaft of a reducer. Background technique [0002] The reducer is widely used in the driving part of mechanical equipment due to its characteristics of large reduction ratio, high precision, high rigidity and high load capacity. The output shaft of the reducer is an important part connected with mechanical equipment. The diameter and length of the output shaft of the reducer are important reference data for the design of the drive pulley. In practical applications, considering various factors of mechanical equipment, the length of the output shaft of the optional standard reducer is not long enough to meet the requirements of use, and special customization will lead to a significant increase in cost. Contents of the invention [0003] Aiming at the defects of the prior art, the technical problem to be solved by the p...
