Abstract
A combined bearing device for bearing an axial load through combination of a ball, a small shaft and a bearing belongs to a combined bearing device capable of simultaneously bearing a radial load and a larger axial load; and the problem that the traditional bearings for bearing the axial load, such as thrust bearings and radial-thrust bearings, cannot bear larger axial load or the friction resistances of the traditional bearings are increased when the axial forces are increased is solved so as to increase the mechanical efficiency. According to the utility model, the combined bearing device comprises a stopping block, a ball, a small shaft, a small bearing, a device main body and a big bearing, wherein as contacting surfaces between the ball and the stopping block, between the ball and the small shaft and between the ball and a rotating shaft are very small and relative rotating resisting moments between the ball and the threes are also very small, power loss is very small during the rotation of the rotating shaft. The combined bearing device provided by the utility model has the advantages of simple structure, easiness for machining and convenience for maintenance and is suitable for supporting rotating shafts with axial load.
Description
Technical field
The utility model belongs to a kind of radial load and larger axis of can bearing simultaneously to the combination bearing device of load, is specifically related to a kind ofly utilize ball, little axle and bearing combination to bear the supporting type of thrust load.Can be used for being supported with larger axis to the running shaft of power load.
Background technique
In engineering, when running shaft has thrust load, usually adopted thrust-bearing and radial thrust bearing etc. to bear thrust load in the past.
Summary of the invention
The utility model provides a kind of incompatible device that bears thrust load of ball, little axle and bearing pack that utilizes, the bearing that the existing thrust-bearing of solution and radial thrust bearing etc. bear axial force load can not bear larger axis to the problem of load or surface friction drag increase when axial force increases, to improve mechanical efficiency.
The utility model is a kind ofly to utilize ball, little axle and bearing combination to bear the device of thrust load; It is characterized in that: it comprises block, ball, little axle, little bearing, apparatus main body and large bearing; Block has been processed as externally threaded cock, and the screwing device main body contacts with ball; Ball is spherical steel ball; Little axle contacts with ball and cooperates with little bearing inner race; Little bearing is radial bearing; Apparatus main body is a cylindrical shell, one end external diameter is processed into shoulder and is threaded the hole, be used for installing, center hole at this end has one section to be processed as internal thread screw-in block, ball, little axle and little bearing are installed for through hole in the middle part, the other end is processed with large bearing mounting hole, also can be designed as required the end and is threaded the hole, in order to bearing (ball) cover to be installed; Large bearing is radial bearing, diametrically running shaft is had supporting role.
Described device, it is characterized in that: ball and little axle are under the responsive to axial force of running shaft, when in the apparatus main body endoporus, rotating, although the active force (axial force) between steel ball and block, little axle and the running shaft is larger, but because ball and block, little axle and running shaft surface of contact are very little, resistance is just very little in relative rotation between ball and the three.The power loss of running shaft was very little when therefore ball rotated in apparatus main body.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure, block 1, ball 2, little axle 3, little bearing 4, apparatus main body 5, large bearing 6, running shaft (7).
Embodiment
As shown in Figure 1, the utility model comprises block 1, ball 2, little axle 3, little bearing 4, apparatus main body 5 and large bearing 6.Wherein block 1 plays rotating bearing ball 2; Ball 2 bears thrust load; Little axle 3 rotating bearing balls 2; Little bearing 4 is little axle 3 radial locations; Apparatus main body 5 is combined on the equipment of being installed in each part, plays the fixed installation effect; Large bearing 6 has the supporting positioning action to running shaft (7) diametrically.In use, running shaft (7) passes large bearing 6, axial end contacts with ball 2, because ball 2 is very little with the surface of contact of each end of block 1, little axle 3 and running shaft (7), so resisting moment is also very little in relative rotation between ball 2 and three's end face, so the power loss of ball 2 running shaft (7) when apparatus main body 5 interior the rotation is less.
In the utility model, block 1 all can be determined according to the concrete condition of carrying with the quantity of Placement, ball 2, little axle 3, little bearing 4 and the large bearing 6 of apparatus main body 5 and material and the size of each part.
The utility model is simple in structure, is easy to processing, and is easy to maintenance, is applicable to the supporting of the running shaft of axial force.
