Description
Technical field
The utility model belongs to chain processing technique field, relates to a kind of chain, specifically a kind of chain tensioner fatigue experimental device.
Background technology
Chain is generally chain link or the annulation of metal, multiplexly does mechanical drive, traction.The quality of chain is the basis ensureing chain safe handling, and the chain processed needs to detect its performance by multiple means.As checked, whether its inside/outside chain sheet is out of shape, whether pin is out of shape or rotate, whether joint gets loose distortion, running time be as good as sound or abnormal vibration etc.In addition, when chain length precision measure, the measurement load specified need be applied on chain, make upper and lower both sides chain tension; For removing the play of whole chain, measure pulling tension state to a certain degree will be applied on chain under.Now in order to ensure machining precision and the serviceable life of chain, provide a kind of tensioner fatigue experimental device.
Utility model content
The purpose of this utility model is to provide a kind of easy to use, chain tensioner fatigue experimental device of saving manpower and cost.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of chain tensioner fatigue experimental device, this test unit comprises motor-driven drive roll, drive roll is connected with chain one end;
The chain other end is connected to driven roll, and driven roll two ends roll shaft is arranged on the first draw frame and the second draw frame middle level, and the first draw frame is connected by the framework bottom it with the second draw frame, and the first draw frame bottom is provided with work drive motor;
Work drive motor, by belt drives belt pulley, makes the roll shaft at the first helical worm, the second helical worm driving driven roll two ends.
The first described draw frame bottom is also provided with movable motor, and movable motor is run along guide rail by the pulley of the second gear case drive installation bottom the first draw frame and the second draw frame.
Described first helical worm, the second helical worm lay respectively at the middle level of the first draw frame and the second draw frame.
The beneficial effects of the utility model: the utility model eliminates hand labor, save manpower; Reduce the cost buying testing equipment; Avoid the generation of chain unfavorable condition, during test, chain is smooth, a degree is consistent, improves product quality, ensure that serviceable life.
Accompanying drawing explanation
The utility model to be further described below in conjunction with accompanying drawing for the ease of it will be appreciated by those skilled in the art that.
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model Worm gear mechanism structural drawing.
Embodiment
A kind of chain tensioner fatigue experimental device, this test unit is for detecting chain under long-time tensioner duty, the service condition of chain, as shown in Figure 1, the drive roll 3 that motor 1 is driven by the first gear case 2, drive roll 3 two ends are arranged in the frame 20 at two ends by bearing and bearing seat, drive roll 3 is provided with tested chain 4, chain 4 other end is connected with driven roll 5, driven roll 5 two ends roll shaft is arranged on the middle level support body of the first draw frame 6 and the second draw frame 7 by bearing and bearing seat, first draw frame 6 and the second draw frame 7 may carry driven roll 5 and move.First draw frame 6 and the opposing parallel setting of the second draw frame 7, the framework 11 bottom it is connected to the first draw frame 6 and the second draw frame 7.First draw frame 6 bottom support body is provided with movable motor 10 and work drive motor 13, and movable motor 10 is by the second gear case 12 drive pulley 8, and pulley 8 is bottom the first draw frame 6 and the second draw frame 7, and the second gear case 12 drive pulley 8 is run along guide rail 9.Work drive motor 13 drives the 3rd gear case 14, and by belt 15 drive pulley 16.Belt pulley 16 rotation direction drives Worm gear mechanism by transmission axle 18, as Fig. 2, and drives the second helical worm 19.Vertical strap is taken turns in 16 rotation directions, drives the other end of the first helical worm 17, first helical worm 17, second helical worm 19 also all to be driven the roll shaft at driven roll 5 two ends by Worm gear mechanism by Worm gear mechanism.First helical worm 17, second helical worm 19 lays respectively on the middle level support body of the first draw frame 6 and the second draw frame 7.
During work, movable motor 10 drives the first draw frame 6, first draw frame 6 to utilize framework 11 to drive the second draw frame 7 jointly to run on the rail 9, in order to adapt to the test needs of different size length chain.Work drive motor 13 is by belt 15 drive pulley 16, and sprocket wheel 16 drives the first helical worm 17, second helical worm 19, thus drives the roll shaft at driven roll 5 two ends to run, and chain 4, by driven roll 5 at the uniform velocity synchro-draw, completes drawing work.Otherwise motor 1 drives drive roll 3 by the first gear case 2, at the uniform velocity synchro-draw chain 4, completes negative drawing work.Repeat aforesaid operations, carry out the torture test of chain tensioner.
This tensioner fatigue experimental device, eliminates hand labor, saves manpower; Reduce the cost buying testing equipment; Avoid the generation of chain unfavorable condition, during test, chain is smooth, reticulate pattern varicose degree is consistent, improve product quality.
Above content is only to the utility model structure example and explanation; affiliated those skilled in the art make various amendment to described specific embodiment or supplement or adopt similar mode to substitute; only otherwise depart from the structure of utility model or surmount this scope as defined in the claims, protection domain of the present utility model all should be belonged to.
