Description
Technical field
The utility model relates to dumping truck hydraulic efficiency pressure system field, particularly dumping truck power takeoff and gear type pump transmission connecting mechanism device.
Background technology
The dumping truck gear type pump is the dedicated gear pump, need bear huge moment operation pressure, moment operation pressure reach 30Mpa, even higher.During work, gear type pump output shaft radial beat eccentricity is quite big, and under high pressure conditions, jerk value reaches more than the 0.5mm, is different from the radial beat eccentricity of conventional gear type pump output shaft less than 0.02mm.If the performance requriements of the bindiny mechanism's out of reach radial runout between power takeoff and the gear type pump will cause the displacement of power takeoff and gear type pump to be killed.Therefore; Require bindiny mechanism not only to have the function of transmission; The power that is about to power takeoff is sent to gear type pump through bindiny mechanism, also will have the function of universal transmission, to adapt to the requirement of output shaft degree of eccentricity under the gear type pump high-pressure work state; The diametral load that produces when eliminating gear type pump work avoids damaging gear type pump.
" analytical investigation of large size plastic jetting-moulding device hydraulic power drive system energy saving technology " (author Zhang Yougen; " rubber and plastic technology and equipment " the 35th the 1st phase of volume in 2009) a kind of servomotor and gear type pump transmission connecting mechanism device are disclosed; And disclose following technical characterictic: servo motor shaft is provided with the servomotor spline gear; Gear pump shaft is provided with the gear type pump spline gear, and the servomotor spline gear is connected through drive sleeve with the gear type pump spline gear, and bearing, locating bush are fixed drive sleeve.Gear type pump in this article is the injection machine gear type pump; It is little to bear pressure; High pressure leans on plunger pump supercharging (plunger pump does not produce diametral load); Servomotor power is 1/tens of dumping truck engine power, requires bindiny mechanism only to have the function of transmission, and the power that is about to servomotor is sent to gear type pump through bindiny mechanism and gets final product.Because bearing, locating bush are fixed drive sleeve; The device that forms a fixed connection is captiveed joint servomotor with gear type pump, carry out fixed conveyor; The function that does not have the diametral load that produces when eliminating gear type pump work; Do not provide the clearly enlightenment of eliminating the gear type pump diametral load, therefore, this structure is not suitable for dumping truck yet.
The patent No. 200920353212.2, Granted publication CN201627719U, name are called " power takeoff and gear type pump transmission connecting mechanism device " patent and disclose a kind of power takeoff and gear type pump transmission connecting mechanism device; Mainly comprise power takeoff and gear type pump; Be in transmission connection through bindiny mechanism between power takeoff and the gear type pump; Bindiny mechanism comprises connection overcoat, spline adapter sleeve I, spline adapter sleeve II and spline adapter sleeve III; The power takeoff castellated shaft of power takeoff is provided with spline adapter sleeve I, and the gear type pump castellated shaft of gear type pump is provided with spline adapter sleeve III, interconnects through spline adapter sleeve II between spline adapter sleeve I and the spline adapter sleeve III; Between power takeoff castellated shaft and the spline adapter sleeve I, all connect between spline adapter sleeve I and the spline adapter sleeve II through spline.This patent has replaced traditional transmission shaft transmission with three spline housing transmissions, has the advantage of quick for installation, cost-cutting, raising power takeoff and gear type pump right alignment, but the diametral load that produces can't eliminate gear type pump work the time, fragile gear type pump.
The utility model content
The utility model provides a kind of dumping truck power takeoff and gear type pump transmission connecting mechanism device, and the diametral load that produces in the time of eliminating gear type pump work avoids damaging gear type pump, prolongs the work life of gear type pump.
The utility model adopts following technical scheme: dumping truck power takeoff and gear type pump transmission connecting mechanism device; Mainly comprise power takeoff and gear type pump; Be in transmission connection through bindiny mechanism between power takeoff and the gear type pump; Bindiny mechanism comprises connection overcoat, interior male splines adapter sleeve I, female splines adapter sleeve II and interior male splines adapter sleeve III; The power takeoff castellated shaft is provided with interior male splines adapter sleeve I; The gear type pump castellated shaft is provided with interior male splines adapter sleeve III; Between interior male splines adapter sleeve I and the female splines adapter sleeve II, between female splines adapter sleeve II and the interior male splines adapter sleeve III all spline is connected, it is characterized in that: between the contact surface of interior male splines adapter sleeve I and female splines adapter sleeve II, certain automatic compensation gap is all arranged, interior male splines adapter sleeve I, female splines adapter sleeve II and interior male splines adapter sleeve III formation joint coupling between the contact surface of female splines adapter sleeve II and interior male splines adapter sleeve III.
Power takeoff and gear type pump through screw retention at the two ends that are connected overcoat.
The size in automatic compensation gap is decided according to the size of output shaft degree of eccentricity under the gear type pump high-pressure work state between the contact surface of spline adapter sleeve.
Owing between the contact surface of spline adapter sleeve certain automatic compensation gap is arranged, interior male splines adapter sleeve I, female splines adapter sleeve II and interior male splines adapter sleeve III form joint coupling, and the utility model floats power takeoff and is connected with gear type pump; The transmission of floating; Not only the power with power takeoff is sent to gear type pump, and, have the effect of universal transmission; Satisfied the requirement of output shaft degree of eccentricity under the gear type pump high-pressure work state; The diametral load that produces in the time of eliminating gear type pump work avoids damaging gear type pump, has prolonged the work life of gear type pump.
