The invention further provides that: the limiting rod is made of shape memory alloy materials, the limiting rod has a first shape in a first temperature range, the limiting rod has a second shape in a second temperature range, the central line of the limiting rod and the central line of the limiting groove are on the same horizontal line in the first shape, the first rack and the second rack are arranged in a meshed mode, the central line of the limiting rod is bent to be parallel to the central line of the positioning groove in the second shape, and the first rack and the second rack are separated.
The technical scheme is adopted, and the method has the advantages that: the limiting rod is made of shape memory alloy materials and can be made of nickel-titanium memory alloy materials, when the bearing starts to operate, the temperature in the bearing starts to rise and is gradually higher than 40 ℃, the temperature of the nickel-titanium memory alloy which deforms is more than 40 ℃, the deformation temperature is a first temperature range, when the bearing stops operating, the temperature can gradually fall below 40 ℃, the temperature is a second temperature range, when the temperature of the bearing reaches the first temperature range, the limiting rod is in a first shape, the central line of the limiting rod and the central line of the limiting groove are on the same horizontal line, the first rack and the second rack are meshed, when the bearing stops operating, the limiting rod is gradually changed from the first shape to a second shape, and the central line of the limiting rod is bent to be parallel to the central line of the positioning groove in the second shape and the first rack and the second rack are separated; the setting of above-mentioned technique ensures that the bearing when the shut down, and the restriction pole central line is not on same water flat line with the restriction groove central line for operating personnel can easily dismantle down the apron, makes things convenient for operating personnel to change bearing spare part or mends oil to bearing inside.
The invention further provides that: be formed with the roll chamber between bearing inner race and the bearing inner race, two it has the isolating ring, two all to extend towards the roll chamber direction on the apron inner wall the isolating ring sets up with the cooperation of rolling chamber both sides opening part grafting respectively, the isolating ring periphery wall sets up with bearing inner race internal perisporium clearance fit, the isolating ring internal peripheral wall sets up with bearing inner race periphery wall clearance fit.
The technical scheme is adopted, and the method has the advantages that: the setting of isolating ring in the above-mentioned technique ensures that external impurity can not invade in the rolling chamber, further increased the sealing performance of apron to the bearing.
