Description

Agricultural machinery chain fatigue wear testing machine
Technical field
The utility model relates to a kind of chain wear testing machine, a kind of chain in agricultural machinery abrasion tester under complex loading conditions of simulating specifically, can test many bar chains simultaneously, it is a kind of compact conformation, efficiency is high, stable drive, the Novel rural facility friction wear testing machine that dependable with function is strong.
Background technology
Traditional chain wear testing machine, the failure mode of research is fracture or the abrasive wear of chain under simple stress condition mostly. And the condition of work of the chain of agricultural machinery is generally more severe, stress condition complexity, chain withstands shocks after load may there is fracture by fatigue, concussion fracture, traditional experiment machine can not be simulated practical application condition well. Therefore, can produce a kind of efficiency high, the Novel rural facility friction wear testing machine tool that the shock loading that can bear in actual applications for the chain of agricultural machinery is simulated is of great significance.
Summary of the invention
The purpose of this utility model is to improve conventional efficient, and the simulation chain stress condition of complexity in actual applications, has optimized testing machine impact loading mechanism and transmission mechanism.
The technical scheme in the invention for solving the technical problem is: the utility model contains (10) such as base (6), column (5), installing plate (4), annular backup pad (3), lower retainer (7), holder (2), loading disc (11), shock loading loading motor (16), main shaft (15), spindle motor (13), magnetic powder brakes. Bracing frame is connected with base by bolt, and installing plate is bolted on bracing frame, and annular backup pad and upper and lower retainer are arranged on installing plate. Sprocket wheel, magnetic powder brake and loading disc are installed on retainer. Gear reduction and slider-crank mechanism are installed on shock loading loading motor, and one end of loading spring is connected with slide block by pin, and the other end is connected with load bar by pin. Main shaft planetary reduction gear is installed at the installing plate back side, and spindle motor is arranged on planetary reduction gear shell, and main shaft is connected on planetary reduction gear output shaft by key.
The beneficial effects of the utility model are the chargers that increased shock loading, make testing machine experiment condition closer to actual service conditions. Adopt asymmetrical load mode, reduced testing machine volume, strengthened testing machine rigidity, can carry out the test of multichain bar simultaneously. Can regulate the size of shock loading by changing the loading spring of different coefficient of elasticity.
Brief description of the drawings
Fig. 1 is the overview of this chain wear testing machine.
Fig. 2 is transmission and the load maintainer figure of this chain wear testing machine.
In figure, be labeled as: 1-chain to be tested, 2-holder, 3-annular backup pad, 4-installing plate, 5-column, 6-base, 7-lower retainer, 8-by movable sprocket, 9-loading sprocket wheel, 10-magnetic powder brake, 11-loading disc, 12-load bar, 13-spindle motor, 14-planetary reduction gear, 15-main shaft, 16-shock loading loading motor, 17-impact loading spring, 18-connecting rod.
Detailed description of the invention
As shown in Figure 1, holder (2) has groove together with passing through bolted with lower retainer (7) on retainer, and with the slide block composition moving sets on magnetic powder brake (10), magnetic powder brake (10) can be along main shaft diameter to doing small movement like this. On magnetic powder brake (10), be equipped with by movable sprocket (8), in the time loading sprocket wheel (9) rotation, and then rotated by movable sprocket (8), now regulate the input current of magnetic powder brake (10) just can control the size of its moment of resistance, the torsion load in simulation chain actual motion.
As shown in Figure 2, planetary reduction gear (14) is installed on spindle motor (13), reducer output shaft is connected by key with main shaft (15), and main shaft empty set is in the hollow shaft of loading disc (11). Shock loading loading motor (16) is fixed on installing plate (4), be converted to the reciprocating motion of slide block by rotatablely moving by slider-crank mechanism, slide block is connected with impact loading spring (17) by pin, and the spring other end is connected with load bar (12) by pin. Load bar (12) is connected with loading disc (11), has 3 symmetrical holes on loading disc (11), and connecting rod (18) one end is connected with hole by pin, and the other end is connected with magnetic powder brake (10) by pin. The shock loading of shock loading loading motor (16) is delivered to load bar (12) by impacting loading spring (17), be delivered to loading disc (11) with the form of moment of torsion again, finally be delivered to magnetic powder brake (10) by connecting rod (18), by magnetic powder brake, shock loading be delivered on test chain. The rotating speed of adjusting shock loading loading motor (16) just can regulate the frequency of shock loading, just can regulate the size of shock loading, to simulate different actual loading situations by changing the loading spring (17) of different coefficient of elasticity.
