Checking the bearings of the driven shaft of a variable gearbox for durability

The distribution of bulbs along the length of the planting furrow during planting significantly affects the yield of onions, since the feeding area of the cultivated crop is formed. The planting apparatus has a significant impact on the quality of planting onions, the uniformity of the distribution of bulbs along the length of the planting furrow at the required distance from each other depends on its operation. To drive the planting machines of onion planters, chain reducers with replaceable sprockets are usually used. The design of a stepless gear of an onion planter with selected bearings and their calculation for durability is proposed.
