Abstract
Frictional force is generated due to sliding between a crank shaft and a bearing pad, and the energy consumption is influenced due to generation of the frictional force, accordingly, people try to find a solution to realize lubrication so as to reduce the generation of the frictional force, but the effect is not ideal, and the best method for eliminating the frictional force is to change the sliding into rolling and mount a needle bearing between the crank shaft and the bearing pad. The invention is characterized in that how to mount the needle bearing between the bearing pad and the crank shaft is illustrated in a specific embodiment.
Description
Technical field: axle and watt use there to be very long history, in the traffic tool in ancient times, between axle and wheel, by slip, travel, so travel, will produce very large frictional force, will affect like this speed and the carrying capacity of the traffic tool.In the middle of axle and wheel, settled after bearing afterwards, with regard to the frictional force problem of good solution axle and wheel.Up to the present, between a lot of axles and wheel, be exactly because settled after bearing, they are all without having rubbed when rotating.In like manner, between the bent axle using now at us and bearing shell, still slide, so also just produced a lot of frictional force, namely waste a lot of energy, a lot of output powers have namely been reduced, between bent axle and bearing shell, settle needle bearing so, namely the slip between bent axle and bearing shell is become to rolling, so just solved the frictional force problem between them.
Technical background: because the slip between bent axle and bearing shell will produce frictional force, thus will consumed energy, will reduce output power, just as the wheel of automobile, if there is no bearing between wheel and axle, result is to have well imagined so.Between bent axle and bearing shell, settling needle bearing, their rotation is also just as the wheel of automobile so.
Summary of the invention: because I am when using piston type high pressure water pump, when I am when improving the pressure of water pump, the phenomenon of heating locking has just appearred in bent axle and bearing shell.I had just settled needle bearing between bent axle and bearing shell afterwards, and in the situation that motive force is constant, the pressure ratio of water pump had improved more than 1/3rd originally like this, and without oil lubricating, so also solved the problem of frequent change engine oil.If be all to settle needle bearing in the place of various use bent axles and bearing shell, in the situation that motive force is constant, just can improve a lot of output powers, in like manner, in the situation that output power is constant, just can reduce a lot of motive force.Also so much machine oil need not have been consumed.Main contents of the present invention that Here it is.
Accompanying drawing explanation: accompanying drawing is exactly in order to illustrate that needle bearing is at the installation position of bent axle and bearing shell.
Embodiment: in order to eliminate the frictional force between bent axle and bearing shell, will settle needle bearing between bent axle and bearing shell.First process an axle, then on axle, process one keyway, then process as required several cylindrical bodys, each cylindrical body is the eccentric opening with convex according to the needs processing of angle, reprocess several intermediate isolating covers, while then assembling, just needle bearing is also installed just passablely simultaneously, then bearing shell is installed just passable.How Here it is solves needle bearing has been arranged to the key issue between bent axle and bearing shell,
Claims (1)
1. because of feature of the present invention, be, in order to eliminate the frictional force between bent axle and bearing shell, so just settled needle bearing between bent axle and bearing shell.
