Abstract
The utility model discloses a novel-type bearing mechanism for electrical machines. The mechanism consists of a roller bearing (1) and a ball bearing (2) which are arranged in parallel. The external diameter of the ball bearing (2) is smaller than that of the roller bearing (1) while the internal diameter of the ball bearing (2) is greater than that of the roller bearing (1). The designed structure of the utility model can ensure that an electrical machine withstands the bearing strength at a smaller size and lighter weight, therefore greatly reducing production costs.
Description
Technical field
The utility model relates to a kind of fore bearing composite structure of motor, relates in particular to a kind of novel bearing structure that is used for motor.
Background technique
At present, the fore bearing structure that middle size motor is commonly used is made up of two bearings, one is the single row roller bearing of ISO size 2 series, one is the single-groove grooved ball bearing of ISO size 2 series, the internal diameter of two bearings, external diameter and width dimensions are the same, roller bearing is used for the radial load of bear rotor, and ball bearing is used for the axial load of bear rotor.This bearing structure can not guarantee the load requirement of motor sometimes, and cost is also bigger, can have influence on the price of complete machine of motor.
Summary of the invention
The purpose of this utility model provides the novel bearing structure that a kind of load that can guarantee motor requires.
The problem of the required solution of the utility model realizes by the following technical solutions: it comprises that roller bearing and ball bearing form side by side, it is characterized in that: the outside dimension of described ball bearing is less than the outside dimension of roller bearing, and internal diameter size is greater than the internal diameter size of roller bearing.
The said structure that the utility model adopts can guarantee the load requirement of motor, reduces the boundary dimension and the weight of motor, has also reduced cost.
Description of drawings
Be described further below in conjunction with 1 pair of the utility model of accompanying drawing:
Accompanying drawing 1 is depicted as structural representation of the present utility model
Embodiment
By accompanying drawing 1 as can be known, this novel bearing structure that is used for motor comprises that roller bearing 1 and ball bearing 2 form side by side, and the outside dimension of described ball bearing 2 is less than the outside dimension of roller bearing 1, and internal diameter size is greater than the internal diameter size of roller bearing 1.Bearing the ball bearing of axial force and can select ISO size 0 serial bearing littler than roller bearing outside dimension, the big 10mm of internal diameter size for use, greatly reduce cost, is example with 6228 bearings, 6228 bearing prices are 1410 yuan, after changing 6030 bearings into, price is 958 yuan, cost savings nearly 47%.
Claims (1)
1. novel bearing structure that is used for motor comprises that roller bearing and ball bearing form side by side, and it is characterized in that: the outside dimension of described ball bearing is less than the outside dimension of roller bearing, and internal diameter size is greater than the internal diameter size of roller bearing.
