Abstract
The utility model discloses a tool for testing a slewing bearing. The tool comprises a base, a slewing bearing and a crane jib; an inner ring of the slewing bearing is fixed on the base through an inner ring connecting plate; the crane jib is fixed on an outer ring of the slewing bearing through an outer ring connecting plate; a hydraulic motor is fixedly arranged on one side of the base; the hydraulic motor is drivingly connected to the outer ring of the slewing bearing; and the crane jib is provided with a load. According to the tool for testing the slewing bearing, through applying a load that exceeds the bearing capacity of the slewing bearing on the crane jib and with the hydraulic motor driving the slewing bearing to be in a slew motion, the tool having a reasonable structure can test the damage of the slewing bearing so as to judge whether the bearing capacity can achieve technical requirements; the tool provided by the utility model is advantaged in convenient detection process and reliable detection results; further, the tool dose not need to be assembled on special equipment for performing testing and has a good practical value.
Description
Technical field
The utility model relates to the detection range of pivoting support, is specifically related to a kind of pivoting support test fixture.
Background technology
Pivoting support is turntable bearing again, is also referred to as: swivel bearing, the supporting of circling round.Pivoting support is used very extensive in real industry, is called as " joint of machine ", is need do relative gyration between the two articles, need bear the mechanical necessary important transmission original paper of axial force, radial force, tilting moment again simultaneously.Along with developing rapidly of mechanical industry, pivoting support has obtained using widely in ship equipment, engineering machinery, light industry and machinery, metallurgical machinery, medical machinery, industrial machinery people, rock tunnel(ling) machine, revolving stage lamp industry.
Pivoting support needed to detect the load-bearing capacity of swing bearing and the serviceable life of pivoting support before dispatching from the factory, to judge the load-bearing capacity of pivoting support.Existing detection mode all is swing bearing to be assembled on some special-purpose use equipment detect, and not only installation process is complicated, and cost is higher, and because the technical parameter of distinct device is different, testing result is not very reliable.
The utility model content
The purpose of the utility model provides a kind of pivoting support test fixture, detects the load-bearing capacity of pivoting support and the serviceable life of pivoting support.
The technical scheme of the utility model is following:
A kind of pivoting support test fixture; Include base, pivoting support and arm; It is characterized in that: the inner ring of said pivoting support is fixed on the base through the inner ring web joint, and described arm is fixed on through the outer ring web joint on the outer ring of pivoting support, and a side of said base is installed with oil motor; The outer ring of described oil motor and said pivoting support is in transmission connection, and on the described arm load is housed.
Described pivoting support test fixture is characterized in that: the outer wall around the pivoting support outer ring is provided with gear ring, on the said hydraulic motor output shaft gear is installed, the gear ring engagement on the outer ring outer wall of described gear and pivoting support.
The beneficial effect of the utility model:
The utility model is rational in infrastructure; Through being applied to the load that surpasses the pivoting support load-bearing capacity on the arm, drive pivoting support by oil motor and do gyration, the damaged condition of inspection pivoting support judges that can its ability reach technical requirement; Testing process is convenient; Testing result is reliable, need not to be assembled on the specialized apparatus to detect, and has good practical value.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the package assembly synoptic diagram of the utility model base, pivoting support and arm.
Embodiment
Referring to Fig. 1,2, a kind of pivoting support test fixture includes base 5, pivoting support 3 and arm 1; The inner ring of pivoting support 3 is fixed on the base 5 through inner ring web joint 4, and arm 1 is fixed on through outer ring web joint 2 on the outer ring of pivoting support 3, and a side of base 5 is installed with oil motor 7; Outer wall around pivoting support 3 outer rings is provided with gear ring; Gear 6 is installed on the output shaft of oil motor 7, the gear ring engagement on gear 6 and the pivoting support 3 outer ring outer walls, thus realize that the oil motor 7 and the outer ring of pivoting support 3 are in transmission connection; Oil motor 7 is in transmission connection with the outer ring of pivoting support, on the arm 1 load is housed.
On arm 1, apply the load above pivoting support 3 load-bearing capacitys, do gyration by oil motor 7 driven gears 6, gear 6 drives pivoting support 3 and does gyration, and arm 1 is done gyration with pivoting support 3.Through after the running of certain hour, pivoting support 3 is pulled down its damaged condition of inspection, thereby load-bearing capacity and the serviceable life of judging pivoting support 3 can reach technical requirement.
Claims (2)
1. pivoting support test fixture; Include base, pivoting support and arm; It is characterized in that: the inner ring of said pivoting support is fixed on the base through the inner ring web joint, and described arm is fixed on through the outer ring web joint on the outer ring of pivoting support, and a side of said base is installed with oil motor; The outer ring of described oil motor and said pivoting support is in transmission connection, and on the described arm load is housed.
2. pivoting support test fixture according to claim 1 is characterized in that: the outer wall around the pivoting support outer ring is provided with gear ring, on the said hydraulic motor output shaft gear is installed, the gear ring engagement on the outer ring outer wall of described gear and pivoting support.
