Bevel Gears – Wear and Bushings

Bheem removed the the bevel gears connecting the four faces. The top gear shows considerable amount of wear. The edges have become sharp as evident from the pictures. His initial plan was to exchange the top bevel gear with the lower one which has much less wear. This didn’t work out as the two gears had different mounting holes. The pics are already in the drive folder.    After showing the gears to Prof. Sangwan the gear were put back next day. He was also saying the bushings on the faces have worn out too which need to be replaced after convocation.Bottom gear 2 Bottom gear 1 Top gear 1 Top gear 2
