Abstract
The invention relates to a novel rolling bearing structure which comprises a bearing outer cover, an oil filling hole, a bearing sleeve, a bearing inner cover and a labyrinth ring. The bearing outer cover and the bearing inner cover are arranged at both ends of the bearing sleeve, a double-row cylindrical roller bearing is arranged between a motor shaft and the bearing sleeve, and an oil flinger A and an oil flinger B are respectively arranged on both sides of the double-row cylindrical roller bearing. According to the structure provided by the invention, as only one bearing is arranged at a transmission end, the limit rotating speed of only one bearing is taken into consideration during the design, so that the range limit to the limit rotating speed of a motor is loose so that the speed regulating range is wide.
Description
Technical field
The present invention relates to bearing structure, particularly relate to the new-type rolling bearing structure that is used in the Middle Size DC.
Background technique
Rolling bearing is that the axle of running and the sliding friction between the axle bed are become rolling friction, thus the mechanical component of a kind of precision of the loss of reducing friction.Raising along with the rolling bearing production technology, the direct current generator bearing of diameter of shaft between 220～280mm progressively adopts rolling bearing in recent years, but the diameter of axle greater than the direct current generator of 300mm adopt rolling bearing at home seldom, also be three bearing structures even adopt rolling bearing.So-called three bearing structures refer to that the driving end at axle is spheric roller bearing and roller bearing, and the non-transmision end of axle is roller bearing.Direct current generator needs speed governing, but because the motor diameter of axle is to calculate by base speed, and the bearing reference rotation velocity is by at a high speed examination, therefore direct current generator adopts three bearing structures, to consider simultaneously two bearing limit speeds, cause the speed adjustable range of motor to diminish, can not satisfy the speed governing operating mode of direct current generator, and driving end adopts the two bearings construction cost higher.
Summary of the invention
The object of the present invention is to provide a kind of speed governing operating mode that can satisfy direct current generator, can reduce again the new-type rolling bearing structure of motor cost.
The present invention realizes like this, the new-type rolling bearing structure, comprise bearing end cover, oil hole, bearing housing, internal bearing cover, labyrinth ring, it is characterized in that: the bearing housing two ends are provided with bearing end cover and internal bearing cover, be provided with Biserial cylindrical roller bearing between motor shaft and the bearing housing, the described Biserial cylindrical roller bearing left and right sides is respectively arranged with disc A and disc B.
Further, be provided with the oil hole 4 that is communicated to Biserial cylindrical roller bearing 5 in the described bearing housing.
The present invention only need to consider the limit speed of a bearing because driving end only has a bearing during design, the scope restriction of motor limit speed is wanted loose, and speed adjustable range is wider.
Description of drawings
Fig. 1 is structural representation of the present invention.
Among the figure 1, motor shaft, 2, bearing end cover, 3, disc A, 4, oil hole, 5, Biserial cylindrical roller bearing, 6, bearing housing, 7, disc B, 8, internal bearing cover, 9, labyrinth ring.
Embodiment
The invention will be further described below in conjunction with accompanying drawing:
A kind of new-type rolling bearing structure, comprise bearing end cover 2, oil hole 4, bearing housing 6, internal bearing cover 8, labyrinth ring 9, it is characterized in that: bearing housing 6 two ends are provided with bearing end cover 2 and internal bearing cover 8, be provided with Biserial cylindrical roller bearing 5 between motor shaft 1 and the bearing housing 6, the described Biserial cylindrical roller bearing left and right sides is respectively arranged with disc A3 and disc B7; Be provided with the oil hole 4 that is communicated to Biserial cylindrical roller bearing 5 in the described bearing housing 6.During implementation, driving end bearing of the present invention adopts Biserial cylindrical roller bearing, this bearing is except having very high radial load bearing capacity, also can bear the axial load that acts on both direction, and the energy self-aligning can bear larger alignment errors, not only economizes on the use of funds, reduce difficulty of processing, and can guarantee the good operation of motor; Oil circuit of the present invention is more reasonable, and grease injects in the middle of bearing housing 6, the shunting along Biserial cylindrical roller bearing 5 to both sides, and the disc A3 that Biserial cylindrical roller bearing 5 both sides arrange and disc B4 have guaranteed that effectively grease can discharge by oil circuit smoothly.
Claims (2)
