A kind of used in new energy vehicles bearing, including bearing inner ring, ball fixed ring, bearing ball, outer race, transmission shaft are solid
Determine foot, bearing fixed feet, dust-proof cushion, sealing ring, oil filler point, oil fuel tube and check-valves, is provided with rolling on the outside of the bearing inner ring
Pearl fixed ring, the ball fixed ring roll inside are connected with bearing ball, and the outer side roll of the bearing ball is connected with bearing
Outer ring is fixedly connected with transmission shaft fixed feet inside the bearing inner ring, it is solid that bearing is fixedly connected on the outside of the outer race
Determine foot, the bearing inner ring and outer race two sides are fixedly connected to dust-proof cushion, are provided with oil filler point on the outside of the dust-proof cushion,
The oil filler point side is connected with oil fuel tube, and the oil fuel tube is internally provided with check-valves.
Further, described oil fuel tube one end is connected with bearing ball.
Further, sealing ring is provided between the dust-proof cushion and bearing inner ring and outer race.
Further, the transmission shaft fixed feet particular number is eight groups.
Further, the bearing fixed feet particular number is eight groups.
Compared with prior art, the utility model has the following beneficial effects: this kind of used in new energy vehicles bearing:
1, it is fixed by the transmission shaft of setting and bearing fixed feet, bearing main body and transmission shaft can firmly be inserted
Pin type is fixed, and is prevented bearing from following transmission shaft to rotate together during working rotation, is significantly increased bearing ball
Roll capability increases transmission efficiency, while reducing the abrasion efficiency of bearing, increases the service life of bearing.
2, by the bearing ball fixed ring of setting, bearing ball can be limited, prevents bearing ball free, increases
Add the globality of bearing ball, the sealing of bearing can be increased by increasing transmission efficiency by the dust-proof cushion and sealing ring of setting
Property, it prevents extraneous dust from entering inside bearing ball and causes greasy filth, effectively bearing is avoided the case where insufficient lubrication occur.
3, by the oil filler point of setting and oil fuel tube, maintenance personal can be facilitated to carry out oil injection operation to bearing ball, increased
The lubricating ability for adding bearing ball increases the roll capability of bearing, by the check-valves of setting, can prevent near bearing ball
Lubricating oil reflux, lubricant effect can be increased, increase the rolling efficiency of bearing.
