Abstract

The utility model discloses a novel rolling bearing structure which comprises a bearing outer cover, an oil filler hole, a bearing sleeve, a bearing inner cover and a labyrinth ring, wherein the bearing outer cover and the bearing inner cover are arranged at the two ends of the bearing sleeve; a double-row cylinder roller bearing is arranged between a motor shaft and the bearing sleeve; and an oil flinger A and an oil flinger B are arranged on the left side and the right side of the double-row cylinder roller bearing respectively. According to the novel rolling bearing structure, only one bearing is arranged at a driving end, so that the limit speed of only one bearing is required to be considered in design, the limitation to the range of the limit speed of a motor is relaxed, and the speed regulating range is wider.

Description

The new-type rolling bearing structure
Technical field
The utility model relates to bearing structure, particularly relates to the new-type rolling bearing structure that is used in the big-and-middle-sized direct current generator.
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 examination at a high speed, therefore direct current generator adopts three bearing structures, to consider two bearing limit speeds simultaneously, 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 purpose of this utility model is to provide a kind of speed governing operating mode that can satisfy direct current generator, can reduce the new-type rolling bearing structure of motor cost again.
The utility model is to realize 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 utility model only need be considered the limit speed of a bearing because driving end has only a bearing during design, the scope restriction of motor limit speed is wanted looser, and speed adjustable range is wider.
Description of drawings
Fig. 1 is structural representation of the present utility model.
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 utility model is described in further detail below in conjunction with accompanying drawing:
The 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 concrete enforcement, the utility model driving end bearing 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 bigger alignment errors, not only economizes on the use of funds, reduce difficulty of processing, and can guarantee the good operation of motor; The utility model oil circuit 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.
