1, the adjustment of the chain
Chain adjustment should pay attention to the looseness of the chain and the phenomenon of chain climbing, too tight will increase the wear and tear. When adjusting, pay attention to the force of the top tensioning slide rail should be within 5-10 kilograms, in order to be able to pressure the loose edge chain is appropriate, if the use of pressure does not move, then the chain is too tight.
2. Adjustment of bearing clearance
There are two ways to adjust: First, increase or decrease the shims. For bearings with fixed inner ring and adjustable outer ring, the axial clearance can be adjusted by increasing or decreasing the gasket at the bearing cover. Using this method to adjust the bearing clearance mainly include: 1 meter rotary cultivator first axis, 1.25-1.75 meter side rotation rotary cultivator on the first axis and the second axis of the cone bearing, intermediate transmission rotary cultivator cylindrical gear shaft and Knife shaft A tapered bearing at the spline shaft. After checking the adjusted bearing clearance, if there is no measuring instrument and special tool, the shaft can be turned by hand according to experience. There should be no obvious axial turbulence and rotation is flexible. If it is too tight and the rotation is difficult, the spacer should be added. Matsushita should remove the gasket. The second is the adjustment nut. All bearings that are fixed in the outer ring and adjustable in the inner ring can be used to adjust the axial clearance. Adopt this method to adjust mainly include: 1 meter of rotary cultivator middle gear box second shaft, 1.25-1.75 meter side drive rotary cultivator middle gear box on the third shaft cone bearing, middle gear transmission rotary cultivator gear box bevel gear Axle (first axis) bevel gear.
