Oil leakage prevention device of reducer housing

摘要

1. TECHNICAL FIELD OF THE INVENTION;The present invention relates to a device for preventing oil leakage of a reducer housing related to a structure of a housing capable of preventing leakage of oil filled in a reducer housing that decelerates and increases power.;2. The technical problem the invention is trying to solve;Conventionally, by installing the output shaft through the output shaft hole and the bearing 8 through the housing it is not possible to prevent wear in the bearing and the rotating portion. In this gap caused by wear caused oil leakage, there was a disadvantage in that it is impossible to prevent friction, wear and frictional heat caused by oil in the reducer.;3. Summary of solution of design;The output shaft hole formed in the interlocking gear group casing housing of the reduction device of the present invention is projected inwardly from the housing by a shaft tube integral with the housing, but the output gear 40 is formed by the bearing 11 in the shaft tube 20 formed inside the housing. The output gear 40 is fixed to the output shaft 50 and the flange 51 inserted into the shaft tube 20 by the stable shaft installation of the output gear 40 and the oil seal 31 and the coupling 30 together with the stable soccer performance. ) And the design of the feature that can increase the sealing effect by the sealed configuration consisting of the bearing (11).;4. Important uses of the devise;The present invention is designed to prevent leakage due to wear together with the output shaft fixing means of the reduction gear or the transmission.
