Abstract
The utility model relates to a power transmission mechanism. A plurality of steel balls are placed between a big piston and a small piston in the case of the utility model for transferring pressure by the squeeze of the steel balls which are stressed. Thereby, the utility model has the advantages of the mechanical transmission and the hydraulic transmission, such as large transferring power, strong overloading performance and reliable working, and overcomes the defects of the mechanical transmission and the hydraulic transmission, such as big volume, complicated structure, easy seepage, no high-temperature and high-pressure resistance, no chemical corrosion prevention, etc. The utility model can be widely used in various mechanical devices of power transmission and transference, clutching and braking, shock absorption and supporting, force reinforcement, supercharging, etc., and meanwhile, can solve the problem which both the mechanical driving mechanism and the hydraulic driving mechanism can not solve.
Description
The utility model relates to a kind of power-transmitting unit.
At present, power-transmitting unit generally is mechanical transmission mechanism, fluid drive mechanism.Mechanical transmission mechanism complex structure, spatial volume are big, power loss is also big; Fluid drive mechanism also exists easy leakage, non-refractory, defective such as acid resistant alkali not.
The purpose of this utility model just is to overcome above-mentioned defective, designs a kind of shortcoming of avoiding machinery and fluid drive mechanism, integrates machinery again and presses driving mechanism with the ball of the advantage of fluid drive mechanism.
The technical solution of the utility model is that two ends are respectively large and small pistons in the housing, and its main feature is in housing, and many steel balls are arranged between the large and small piston.
Advantage of the present utility model and effect just are to have concurrently the advantage of machinery and fluid drive mechanism mode, can transmit more high-powerly, and the overburdening performance is strong, can bear high temperature, high pressure, resistance to chemical attack, ne-leakage, reliable operation and structure is extremely simple can be widely used in the various machinery.
Description of drawings:
Fig. 1---the utility model structural principle schematic representation.
The reinforcement staking working principle schematic representation of Fig. 2---the utility model practical application.
Embodiment:
As shown in Figure 1, two ends are respectively small pistons 2 in the housing 4, big piston 5, the fixedly connected top board 6 of connecting rod one end of small piston 2 outside housing 4, on small piston 2 connecting rods spring 1 is arranged, spring 1 is outside housing 4, and an end withstands on top board 6 inboards, the other end withstands on the housing 4, between small piston 2, the big piston 5 many steel balls 3 is arranged in the housing 4.When top board 6 is subjected to external force to the right during pressure spring 1, small piston 2 moves right, small piston 2 extruding steel balls 3, and steel ball 3, then promotes big piston 5 and moves right to all directions transmission stressed after steel ball 3 pressure surpass big piston 5 static force.The variation and the hydraulic transfering principle of small piston 2, distance that big piston 5 moves and stressed size are close.
As shown in Figure 2, be when adopting the reinforcement staking working principle schematic representation work of the utility model principle, the screw mandrel 8 of staking 7 is left during pushing tow, pressure spring 1, promote small piston 2 extruding steel balls 3, steel ball 3 pushes mutually, transmits pressure to big piston 5, so housing 4 moves right, compress staking 7 modules; When small piston 2 continued to push steel ball 3 left, the pressure of steel ball 3 constantly increased in the housing 4, after overcoming big piston 5 static force, promoted big piston 5 and pressed to spindle nose 10 by regulating pressure head 9, and belt pulley 11 moves to right under its reaction force promotes and is drawn out.
The utility model principle can also be applied to many aspects, such as the conveying and the transmission of power, clutch and braking, damping and supporting, operation mechanisms such as reinforcement and supercharging; Can solve simultaneously all indeterminable transmission difficult problem of hydraulic transmission or mechanical transmission again.
Claims (1)
1. ball is pressed driving mechanism, and two ends are respectively small piston (2) in the housing 4, and big piston (5) is characterized in that the interior small piston of housing (4) (2), and big piston has many steel balls between (5).
