Abstract
The utility model discloses a bearing device used in a driving wheel. The bearing device comprises two rolling bearings (3) placed in through holes (11) of a driving wheel (1), the bearing device is characterized in that the two rolling bearings (3) are parallelly arranged in the through holes (11) of the driving wheel (1) in a spaced mode, and a spacing ring (41) is arranged between the end surfaces of opposite outer rings (31) of the two rolling bearings (3); and a spacer ring (42) is arranged between the end surfaces of the opposite inner rings (32) of the two rolling bearings (3), when the rolling bearings (3) and driving shafts (2) are fixed together, the driving shafts (2) on the left and right end faces of the rolling bearings (3) are respectively provided with a lock sleeve (5). The design has the advantages that the two rolling bearings are arranged between the driving wheel and the driving shafts, the contact areas between the rolling bearings and the driving wheel are increased, the carrying capacity of the driving wheel is strengthened, the two rolling bearings are symmetrically arranged, the stress of the driving wheel is uniform, and the operation smoothness of the driving wheel is increased.
Description
Technical field
The utility model relates to a kind of bearing means, especially refers to a kind of bearing means for drive wheel.
Background technique
belt pulley, the wheel type drivings such as sprocket wheel are to use the very general kind of drive, only be provided with single rolling bearing between drive wheel in the wheel type driving of prior art and transmission shaft, this structure has following shortcoming: the end face width of single rolling bearing is limited, cause the stress surface between bearing face and drive wheel less, so the bearing capacity of drive wheel is less, also make drive wheel easily produce the phenomenon of application of force inequality in the transmission loading process, thereby the unbalance stress that causes bearing face, make bearing produce eccentric phenomenon, affect the normal operation of bearing, and then affect working life of bearing, therefore its structure is further improved.
The model utility content
Technical problem to be solved in the utility model is to provide a kind of design ingenious, simple in structure for above-mentioned prior art problem, the strong and bearing means that is used for drive wheel that operates steadily of bearing capacity.
the utility model solves the problems of the technologies described above the technological scheme that adopts: this is used for the bearing means of drive wheel, comprise the rolling bearing that is placed in the drive wheel through hole, it is characterized in that: described rolling bearing is two, also to be arranged at column-spacingly in the through hole of drive wheel, and be provided with cage ring between the relative cycle surface of two rolling bearings, be provided with isolating ring between the relative inner ring end face of two rolling bearings, when described rolling bearing and transmission shaft are fixed together, be respectively arranged with lock sleeve on the transmission shaft of both ends of the surface position, described rolling bearing left and right.
As improvement, be provided with internal thread on the inwall of described lock sleeve, and be provided with outside thread on the outer circumferential face of described transmission shaft, described lock sleeve and transmission shaft are by internal thread and externally threaded being spirally connected and fixed with each other.
As improvement, be provided with check washer between described rolling bearing and lock sleeve.
As improvement, be respectively arranged with dust cover between the outer ring at two ends, described rolling bearing left and right and inner ring.
As improvement, the left and right both ends of the surface of described rolling bearing are mutually concordant with the opposite ends face of drive wheel.
Compared with prior art, it is two that the utility model adopts described rolling bearing, also to be arranged at column-spacingly in the through hole of drive wheel, and be provided with cage ring between the relative cycle surface of two rolling bearings, be provided with isolating ring between the relative inner ring end face of two rolling bearings, when described rolling bearing and transmission shaft are fixed together, be respectively arranged with lock sleeve on the transmission shaft of both ends of the surface position, described rolling bearing left and right.The design's advantage is: be provided with two rolling bearings between drive wheel and transmission shaft, and be provided with cage ring between the outer ring of two rolling bearings, be provided with isolating ring between the inner ring of two rolling bearings, increased the area of contact between rolling bearing and drive wheel, strengthened the bearing capacity of drive wheel, again because two rolling bearings for being symmetrical arranged, make the stressed even of drive wheel, thereby increased the drive wheel traveling comfort.
