Description
Technical field
The present invention relates to a kind of sliding bear experiment machine, especially a kind of load maintainer of sliding bear experiment machine.
Background technology
Sliding bearing have load-bearing capacity strong, operate steadily, the advantage such as shock resistance is good, the life-span is long, thus can see its figure from small-sized household electrical appliance to large-scale steel rolling production-line.Sliding bear experiment machine is the fundamental test equipment analyzing sliding bearing bearing mechanism, is to analyze and the lubricating property of research bearing, the important practical basis carrying out innovative design.As the carrier of sliding bear experiment, sliding bear experiment machine is widely used in teaching, scientific research and production division, becomes the key of China's sliding bearing research and manufacture level.Traditional Sliding bearing work bench belongs to mechanical more, and manually to test, inefficiency is not said, has been difficult to the experiment that precision is higher.Some experiment tablees in recent years, owing to combining the present computer technology, in performance with functionally strengthen all to some extent, but from the angle of research, design, their research seems not enough, loading characteristic is single, can not the changeable load of simulating reality operating mode, is difficult to realize testing or testing being changed to synthetic study type by demonstration and verification type.
Summary of the invention
The present invention will provide a kind of load maintainer based on sliding bear experiment machine, it is a kind of sliding bear experiment device load maintainer can simulating actual condition, this load maintainer can provide the steady load of sliding bearing or the load that changes according to certain rules as alternate load etc., can carry out the performance test of sliding bearing according to designing requirement and actual condition.The simple reliable operation of this load maintainer structure, need not change, control plus load characteristic, as long as to change in advance according to testing requirements, install the requirement that specific loaded roll just can realize test load.
For achieving the above object, technical scheme of the present invention is: a kind of load maintainer based on sliding bear experiment machine, comprise sliding bearing base, guide pole, Compress Spring, load lid, guide pole nut, fixing end cap, end cover nut, rolling bearing, loaded roll, be characterized in: sliding bearing base is equipped with guide pole above both sides respectively, be slidably connected above two guide poles and load lid, load on the guide pole between lid and sliding bearing base and be socketed with Compress Spring, stretch out on the guide pole that loads and cover end face and be rotary with guide pole nut, load in lid to be connected by rolling bearing and load axle and loaded roll, before loading lid, rear two ends end cover nut is fixedly connected with fixing end cap.Loaded roll is cylinder loaded roll or the loaded roll by certain circular path.
The invention has the beneficial effects as follows:
Load maintainer based on sliding bear experiment machine of the present invention is a kind of sliding bear experiment device load maintainer can simulating actual condition.This load maintainer can provide the steady load of sliding bearing or the load that changes according to certain rules as alternate load etc., can carry out the performance test of sliding bearing according to designing requirement and actual condition.The simple reliable operation of this load maintainer structure, need not change, control plus load characteristic, as long as to change in advance according to testing requirements, install the requirement that specific loaded roll just can realize test load.This mechanism can provide larger operating load instead of general simulation load, is test more realistic operating mode.Due to the characteristic of loaded roll, for the scientific research, structure, material, lubricating condition exploration etc. of sliding bear experiment provide good basis.
Accompanying drawing explanation
Fig. 1 is structural front view of the present invention;
Fig. 2 is the left view of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the invention will be further described.
As Fig. 1, shown in 2, a kind of load maintainer based on sliding bear experiment machine, comprises sliding bearing base 1, guide pole 2, Compress Spring 3, loads lid 4, guide pole nut 5, fixes end cap 6, end cover nut 7, rolling bearing 8, loaded roll 9.
Sliding bearing base 1 is equipped with guide pole 2 above both sides respectively, two guide poles 2 are slidably connected above and load lid 4, load on the guide pole 2 between lid 4 and sliding bearing base 1 and be socketed with Compress Spring 3, stretch out load lid 4 upper surface guide pole 2 on be rotary with guide pole nut 5, load in lid 4 to be connected by rolling bearing 8 and load axle and loaded roll 9, load lid 4 forward and backward two ends end cover nut 7 and be fixedly connected with fixing end cap 6.
Each parts Main Function:
(1) sliding bearing base 1: for parts such as installation test bearing and connection guide poles.
(2) guide pole 2: one end and sliding bearing base are with being threaded, and the other end is connected with guide pole nut.Play at work and ensure to load cover rim and its guide direction and move and do not produce deflection.
(3) Compress Spring 3: the gap in eliminating machine.And utilize Compress Spring characteristic off-test or suspend time automatically recover virgin state need not manual intervention.
(4) lid 4 is loaded: the test load transmitting hydraulic cylinder during test.
(5) guide pole nut 5: pretension Compress Spring, produces certain pretightning force, keeps the duty of Compress Spring.
(6) fixing end cap 6: for loading the axis of axle, rolling bearing etc. and the fixing of horizontal direction.
(7) end cover nut 7: load lid 4 and fixing end cap 6 for connecting, fixing.
(8) rolling bearing 8: be arranged on the two ends loading axle and reduce loading axle frictional resistance at work and test additional load.
(9) loaded roll 9: loaded roll adopts two kinds of forms, common cylinder loaded roll and the loaded roll by certain circular path.Common cylinder loaded roll can realize stable load hold mode, is then oval roller and making by certain circular path etc. by the loaded roll of certain circular path.Utilize this class feature can realize the simulated condition of Study of Cyclic Loading etc.
Principle of work of the present invention is as follows:
By the assigned address of sliding bearing floor installation on the base of testing machine before test, test bearing, working shaft etc. are connected according to testing requirements and installs.By guide pole, Compress Spring and the loaded roll be pre-installed, rolling bearing, fixing end cap, load the charging assembly installations such as lid on the guide bar also with guide pole nut screwing clamping and locking, make Compress Spring produce certain pretightning force, keep the duty of Compress Spring.After testing machine runs according to testing requirements, hydraulic cylinder is implemented to load working pressure.Now due to loaded roll contacts with working shaft and by working pressure pass to working shaft and test bearing.Because loaded roll is rotated together with working shaft, therefore the contour curve of loaded roll determines the feature of test load.Loaded roll adopts various ways, common cylinder loaded roll and the loaded roll by certain circular path.Common cylinder roller can realize stable load hold mode, by certain circular path loaded roll then or be oval roller or for make by certain circular path.Utilize this class feature can realize the simulated condition of Study of Cyclic Loading.
