Problems solved by technology
For example, Chinese patent CN 204528409 U discloses a gear with bearings. Since the structure adopts the form of deep groove ball bearings embedded in the inner hole of the gear, after long-term use, the inner hole of the gear is prone to wear, resulting in deep groove ball bearings slip off

Embodiment
[0014] Example: as attached figure 1 As shown, this new type of bearing unit with gears includes an outer ring 1, an inner ring 2, rolling bodies 4, a cage 5 and an outer ring gear 7, and the outer ring 1 and the inner ring 2 are held by the cage 5 There are several rolling bodies 4; one side of the outer ring 1 is the first end face 1-1, the other side is the second end face 1-2, the first end face 1-1 extends radially outward to form an extension 1-3, An outer ring gear 7 is arranged on the outer circumference of the extension parts 1-3, and the outer ring gear 7 can mesh with the output gear of the wheel motor to realize wheel driving, that is, the wheel motor drives the outer ring 1 of the bearing unit to rotate.
[0015] Further, a keyway 6 is formed on the outer circumference of the outer ring 1, and the keyway 6 can be connected to install a sun gear through a key, that is, the outer ring 1 rotates while driving the sun gear to rotate, and the sun gear cooperates with t...

The invention discloses a novel bearing unit with a gear, and relates to the field of bearings, the novel bearing unit comprises an outer ring, an inner ring, rolling bodies, a retainer and an outer ring gear, and a plurality of rolling bodies are kept between the outer ring and the inner ring through the retainer; one side of the outer ring is a first end face, the other side of the outer ring is a second end face, the first end face extends outwards in the radial direction to form an extending part, and an outer ring gear is arranged on the outer circumference of the extending part and used for being meshed with an external transmission gear. The bearing unit has the beneficial effects that the gear is integrated on the outer ring of the bearing unit, real integration is achieved, the outer ring gear and the bearing cannot be separated or disengaged after long-term use, the transmission efficiency is high, and the arrangement space in a vehicle is saved.
Description
technical field [0001] The invention relates to the field of bearings, in particular to a novel bearing unit with gears. Background technique [0002] With the development and popularization of electric vehicles, the wheel drive technology applied to electric vehicles has received extensive attention. Due to the limitation of the internal space of electric vehicles, the gears and bearing units required for wheel-side transmission are often designed as a whole to form a bearing unit with gears. For example, Chinese patent CN 204528409 U discloses a gear with bearing. Since the structure adopts the form of deep groove ball bearing embedded in the inner hole of the gear, after long-term use, the inner hole of the gear is prone to wear, resulting in the deep groove ball bearing. slip. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, and provide a novel bearing unit with gears, which has the advantages of...
