Abstract
The invention relates to a closed force flow type chain transmission testing platform. The closed force flow type chain transmission testing platform comprises a driving shaft, a driven shaft and an electromagnetic adjustable-speed motor. The electromagnetic adjustable-speed motor drives the driving shaft which drives the driven shaft, the two ends of the driving shaft are provided with small chain wheels, the two ends of the driven shaft are provided with big chain wheels, the two ends of the driving shaft and the two ends of the driven shaft are respectively provided with a pair of chains, and then a closed force flow is formed. A bearing base of the driven shaft can move up and down through a sliding groove mechanism, the upper end of the bearing base is dragged by a steel wire rope, the steel wire rope winds around a machine frame and then is connected with a spring bumper, and a hook at the lower end of the spring bumper can hang a weight with certain weight to load. The upper end of each big chain wheel is provided with a fuel spray nozzle to connect a hydraulic system to lubricate the chains. The closed force flow is formed by chain transmission of the driving shaft and the driven shaft, and the loss of transmission energy is greatly reduced. The spring bumper can hang the weight, and therefore dynamic loading tensile force is achieved. The closed force flow type chain transmission testing platform is simple in structure, safe, reliable and low in cost, and the loss of the transmission energy of the chain transmission testing platform is greatly reduced.
Description
Technical field
The present invention relates to the chain transmission test bench.Be specifically related to confining force streaming chain transmission test bench.
Background technology
In recent years, the new automobile engine has been applied timing chain more and more widely.The drive sprocket rotating speed of automotive chain is up to more than 5000r/min, far surpass the limit speed that the common roller chain of same model is limited by chain transmission power Curves, the car engine timing gas distributing system also has very high requirement to the polishing machine of timing chain, and the requirements such as the many punchings of the high speed of automotive chain, speed and load alternation and strong wearing quality have formed large technological difficulties and the innovative point in industry.The power that common chain transmission test bench transmits when carrying out the chain transmission test almost completely is wasted, and is not suitable for carrying out chaindriven endurancing.
Summary of the invention
In order to address the above problem, the invention provides confining force streaming chain transmission test bench.
The present invention is achieved through the following technical solutions:
Confining force streaming chain transmission test bench, comprise main drive shaft, driven shaft, bearing seat, wire rope, spring bumper, electromagnetic adjustable speed motor, frame, atomizer, hinge wheel and minor sprocket; Electromagnetic adjustable speed motor drives main drive shaft, main drive shaft drives the driven shaft of its upper end by the chain transmission, both ends of main drive shaft is equipped with minor sprocket, the driven shaft two ends are equipped with hinge wheel, chain all can be installed in the main driven shaft two ends, and an end is chain to be measured, and the other end is for accompanying the examination chain, when this pair of chain is installed, slack list is contrary with pilled-in selvedge, forms confining force stream.Main drive shaft relies on bearing seat to be fixed by bolts on frame, the bearing seat of driven shaft utilizes slide way mechanism to move up and down, the upper end of driven shaft is drawn by wire rope, wire rope has connect spring bumper after walking around frame, the counterweight that the lower end hook of spring bumper can hang constant weight loads, to change the tensile force of chain.The upper end of hinge wheel is provided with atomizer, with the connecting fluid pressing system, realizes the lubricated of chain.
Good effect of the present invention is: the chain transmission of master and slave moving axis forms confining force stream, greatly reduces the transmission energy loss; Spring bumper can hang counterweight, realizes the loaded in tension power of dynamic quantitative.The present invention is simple and compact for structure, practicality and high efficiency, and cost is lower, has more promotional value.
