Abstract
The utility model, which belongs to the bearing test machine technology field, brings forward a radial connection structure for a test bearing and a drive shaft. The radial connection structure includes a shaft sleeve (5) that is used for connecting a test bearing (1) and a drive shaft (2); the shaft sleeve (5) is clamped on the drive shaft (2) and the test bearing (1) is sleeved on the shaft sleeve (5); and an expanding sleeve (4) is arranged on a combining end surface of the shaft sleeve (5) and the drive shaft (2). According to the utility model, the radial connection structure for the test bearing and the drive shaft is provided, so that defects of many replaced tools, high labor intensity for assembling and disassembling and low production efficiency during the test bearing installation process can be overcome. And test bearings with different types, different loads and different rotating speeds can be installed without need of drive shaft replacement.
Description
Technical field
The utility model belongs to the bearing tester technical field, relates generally to the radially syndeton of a kind of test bearing and driving shaft, is used for bearing tester, is particularly useful for a testing machine and changes different model size test bearing.
Background technology
The mounting means of test bearing be divided into loading between fulcrum with loading in overhanging end; Loading needs to change support wheel, driving shaft and a series of parts of bearing enclose between fulcrum the time, and the frock number of packages is many; Big, the waste material of mounting or dismounting labour intensity, part is easy to damage.Loading is when overhanging end, and the axle of test bearing needs to change with a disunity of accompanying the examination bearing, the axle head of test bearing, and such two shaft connection places form weakest link, rigidity, strength degradation, and deflection increases.If the test bearing model is many, the frock frequent change has more increased workman's labor capacity.
The utility model content
The replacing frock is many when installing in order to overcome test bearing; Mounting or dismounting labour intensity is big; The low shortcoming of production efficiency; The utility model proposes the radially syndeton of a kind of test bearing and driving shaft, makes it not only the test bearing of different model, different loads, different rotating speeds can be installed but also need not change driving shaft.
The utility model adopts following technical scheme for accomplishing the foregoing invention task:
The radially syndeton of a kind of test bearing and driving shaft, described radially syndeton has the axle sleeve that is connected with driving shaft in order to test bearing; Described axle sleeve clamping is on driving shaft, and test bearing is nested with on axle sleeve; And axle sleeve is provided with expansion set with the end face that combines of driving shaft.
Has groove on the periphery of said axle sleeve; Be locked in the test bearing and withstand on the bottom surface of sleeve outer circle groove that face has.
The interior cover of said test bearing is compressed by the shaft end ring that is positioned at the axle sleeve left side, and the overcoat of said test bearing is compressed by the left end cap that is positioned at the axle sleeve left and right sides, right end cap; Described left end cap, right end cap are fixed on the loading head.
A kind of test bearing that the utility model proposes and the radially syndeton of driving shaft; It is many to change frock when having overcome in the prior art test Bearing Installation; Mounting or dismounting labour intensity is big; The shortcoming that production efficiency is low can be installed the test bearing of different model, different loads, different rotating speeds and need not be changed driving shaft again.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: 1. test bearing, 2. driving shaft, 3. left end cap, 4 expansion sets, 5. axle sleeve, 6. shaft end ring, 7. right end cap, 8. loading head.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
As shown in Figure 1, the radially syndeton of a kind of test bearing and driving shaft, test bearing has the axle sleeve 5 that is connected with driving shaft 2 in order to test bearing 1 with the radially syndeton of driving shaft; Described axle sleeve 5 clampings are on driving shaft 2, and test bearing 1 is nested with on axle sleeve 5; And axle sleeve 5 is provided with expansion set 4 with the end face that combines of driving shaft 2, through expansion set 4, produces enough friction force, so that axle sleeve 5 transmitting torques, axial force, radial force.Have groove on the periphery of said axle sleeve 5, being locked in the test bearing withstands on the bottom surface of sleeve outer circle groove that face has.The interior cover of said test bearing is compressed by the shaft end ring that is positioned at the axle sleeve left side 6, and the overcoat of said test bearing is compressed by the left end cap that is positioned at the axle sleeve left and right sides 3, right end cap 7; Described left end cap 3, right end cap 7 are fixed on the loading head 8.
During the installation test bearing, shift the axle sleeve 5 that is fit to test bearing onto driving shaft 2, make the position that arrives design code, will unscrew the expansion set 4 of screw and pack connecting hole smoothly into, test bearing 1 is enclosed within axle sleeve 5 cylindricals, withstand end face screw-driving.Shaft end ring 6 is compressed cover in the bearing 1, and left end cap 3 compresses test bearing 1 overcoat with right end cap 7.Left end cap 3 is fixed on the loading head 8 with right end cap 7.The internal diameter of axle sleeve and the external diameter of driving shaft need not to change, and axle sleeve 5 is cooperate with the different model test bearing a plurality of; Only need when needing to change the test bearing model axle sleeve 5 is unloaded, change the axle sleeve 5 that adapts to test bearing, and need not to change driving shaft.
Claims (3)
1. the radially syndeton of test bearing and driving shaft, it is characterized in that: described radially syndeton has the axle sleeve (5) that is connected with driving shaft (2) in order to test bearing (1); Described axle sleeve (5) clamping is on driving shaft (2), and test bearing (1) is nested with on axle sleeve (5); And axle sleeve (5) is provided with expansion set (4) with the end face that combines of driving shaft (2).
2. the radially syndeton of test bearing according to claim 1 and driving shaft is characterized in that: have groove on the periphery of said axle sleeve (5); Be locked in the test bearing (1) and withstand on the bottom surface of sleeve outer circle groove that face has.
