Description

TECHNICAL FIELD

[0001] The utility model relates to bearing anti -loose structure technical field, concretely relates to a taper bearing locking adjustment anti -loose structure. BACKGROUND

[0002] The differential mechanism is the mechanism that makes the left and right drive wheels rotate at different speeds, mainly composed of half shaft gears, planetary gears and differential mechanism housings. Adjusting the gap between the taper bearings plays a role in ensuring normal operation, improving stability and precision, preventing shafting from moving, reducing friction and wear, and adapting to the speed difference adjustment requirements. By accurately adjusting the gap, performance problems caused by over-tightening or over-tightening of the bearings can be avoided, ensuring efficient and stable operation of the differential mechanism under various working conditions, prolonging the service life of the equipment and improving the reliability of the transmission system. The parts that adjust the gap play a key role in the industrial production field, especially in the machining industry, and have a decisive influence on the precision and performance of the product. The adjusting washer is the most common part that adjusts the gap. For split bearing seats, it is not easy to measure the gap, and the thickness of the adjusting washer is difficult to be accurately determined. In addition, the disclosed technology CN206738417U is a bearing anti-loose structure for half shaft, which uses combined locking to prevent loosening, but its method still has room for improvement in application on the differential mechanism support seat. SUMMARY

[0003] The core of the utility model is to provide a taper bearing locking adjustment anti-loose structure, which gradually tightens the adjusting nut by pressing it against the outer ring of the taper bearing, until there is no gap inside, ensuring normal operation of the taper bearing, improving the stability and precision of the equipment, and preventing shafting from moving. The anti-loose washer is fixed on the differential mechanism support seat and used in conjunction with the adjusting nut to lock the adjusting nut and prevent it from loosening, ensuring stable operation of the bearing.

[0004] A taper bearing locking adjustment anti-loose structure, comprising a differential mechanism support seat, the differential mechanism support seat is connected to a reduction gearbox, the differential mechanism support seat and the reduction gearbox are connected by screws, an adjusting nut is placed in the center threaded hole of the differential mechanism support seat, the adjusting nut abuts against the taper bearing at one end, and an anti-loose washer is arranged at the other end of the adjusting nut.

[0005] The taper bearings in the differential mechanism support seat are mainly used for power transmission, friction reduction, rotation precision improvement, and speed difference adaptation during turning. After placing the taper bearings, the gap needs to be adjusted to ensure normal operation of the taper bearings, improve the stability and precision of the equipment, and prevent shafting from moving. In order to adjust the gap of the taper bearing, the adjusting nut is pressed against the outer ring of the taper bearing, and the adjusting nut is gradually tightened until there is no gap inside the taper bearing. After adjustment, the position of the adjusting nut is fixed with the anti-loose washer.

[0006] The anti-loose washer has an extension rod, and the adjusting nut is in a disc structure with a protruding positioning column on the end face. The extension rod can be just clamped between two adjacent protruding positioning columns. The protruding positioning column on the end face of the adjusting nut is designed to allow the anti-loose washer to be clamped in the middle, thereby fixing the position of the adjusting nut. The side surface of the extension rod tightly fits the side surface of the protruding positioning column, and the bottom surface of the extension rod abuts against the end face of the adjusting nut, thereby fixing the adjusting nut.

[0007] The anti-loose washer includes an anti-loose washer body, the side surface of which has the same curvature as the outer circle of the adjusting nut, and can perfectly fit the outer circle of the adjusting nut. The anti-loose washer has a threaded hole inside, and the end face of the anti-loose washer fits the surface of the differential support seat. The surface of the differential support seat also has a threaded hole at the extension position of the bottom of the threaded hole of the anti-loose washer. A screw is placed in the threaded hole, and the screw cooperates with the threaded holes of the anti-loose washer and the differential support seat, thereby fixing the anti-loose washer on the surface of the differential support seat.

[0008] The tapered bearing is in a circular ring structure, with the inner ring abutting against the differential inner shell and the outer ring abutting against the differential outer shell. The tapered bearing is mainly used for transmitting power between the differential inner shell and the differential outer shell and reducing friction therebetween, thereby improving the rotation accuracy.

[0009] The half shaft gear is placed in the differential inner shell hole and meshes with the planetary gear. In the automobile differential support seat, the planetary gear and the half shaft gear work together to ensure smooth operation of the vehicle during turning and reduce tire wear. The planetary gear is located at the center of the differential and is responsible for transmitting power from the drive shaft to the two half shafts. It adjusts the speed difference between the two sides of the wheel by meshing, to meet the demand of higher speed on the outside wheel during turning. The half shaft gear further transmits the power from the planetary gear to the wheels, ensuring that the left and right wheels operate independently at different speeds. When the vehicle is driving straight, the two sides of the wheel rotate at the same speed; when turning, the planetary gear and the half shaft gear can adjust the power distribution as needed to ensure that the wheels rotate at the appropriate speed, thereby improving driving stability and comfort.

[0010] The planetary gear is placed on the planetary gear shaft and can rotate freely around it. In the differential, the planetary gear shaft plays a key role in supporting and guiding the planetary gear, helping to transmit power from the input shaft to the two half shafts to achieve the power distribution function of the differential. The planetary gear shaft works with the planetary gear to adjust the speed difference between the two sides of the wheel during turning, allowing the inside and outside wheels to rotate independently, thereby avoiding skidding and improving the driving stability and comfort of the vehicle. Therefore, the planetary gear shaft is crucial to the normal operation of the differential, ensuring power transmission and smooth driving of the vehicle. The central axis of the adjusting nut, the central axis of the tapered bearing, the central axis of the differential inner shell, and the central axis of the half shaft gear are the same.

[0018] The tapered bearing 5 in the differential support 1 is mainly used for transmission power, reducing friction, improving rotation accuracy, and adapting to the speed difference when turning. After placing the tapered bearing 5, the gap needs to be adjusted to ensure that the tapered bearing 5 can operate normally, improve the stability and accuracy of the equipment, and prevent the shaft system from moving. In order to achieve the purpose of adjusting the gap of tapered bearing 5, the adjusting nut 3 is pressed on the outer ring of tapered bearing 5, and the adjusting nut 3 is gradually tightened until there is no gap in the tapered bearing 5.
