Abstract
The utility model discloses a kind of high reliability, low noise and be used for the auxiliary output interface device of PTO of non-road movable type mechanical front end.It comprises by the pinion unit SAE spline of unifying.Gear train assembly mainly is made up of crankshaft timing gear, idle gear A, idle gear B, carrier gear, oil hydraulic pump gear; The SAE spline is characterized in that its shaft extension form is an involute; Fluid power pressure lubrication assembly mainly is made up of the lubricant pipe parts, and the friction pair that link to each other with the gap bridge tooth are carried out pressure lubrication and cooling, thereby improves the friction pair reliability and reduce noise.When this cover system advantage was to carry higher power output, good reliability, noise were low.Thereby improve the quality of non-road movable type mechanical product.
Description
Technical field the utility model relates to a kind of auxiliary power output interface device, especially for the auxiliary output interface device of the PTO of non-road movable type mechanical front end.
Background technique is along with the fast development of Chinese national economy, and every each industry is more and more higher to non-road movable type mechanical performance requirement.Non-road movable type mechanical mainly comprises engineering machinery, farm machinery woods, forestry machinery and airport ground servicing equipment.Simultaneously, since the entry to WTO, external a large amount of engineering machinery, farm machinery enters China, and engineering machinery, the agriculture machinery industry of China caused very big impact, improves China's engineering machinery, the farm machinery quality of product has been very urgent.But China's non-road movable type mechanical product ubiquity the reliability instability, the shortcoming that noise is big.Though it is a lot of to influence the factor of non-road movable type mechanical product performance, key is auxiliary equipment such as motor, generator, hydraulic system etc., and auxiliary power output interface device also is a major reason.From motor head, PTO auxiliary power output unit is positioned at bottom righthand side, the oil hydraulic pump of using in order to direct installation movable type mechanical hydraulic system.At present, China mostly adopts gear train assembly, is connected with oil hydraulic pump by flat key or rectangular spline.This device exists poor reliability and the big shortcoming of noise, influences the quality of non-road movable type mechanical product.
The summary of the invention technical problem to be solved in the utility model provides the branch power output interface device that is used for non-road movable type mechanical front end of a kind of high reliability, low noise.
For reaching the purpose that solves the problems of the technologies described above, PTO auxiliary power output unit of the present utility model is made up of unify SAE spline and fluid power pressure lubrication assembly of pinion unit.Gear train assembly mainly is made up of crankshaft timing gear, idle gear A, idle gear B, carrier gear, oil hydraulic pump gear, gear chamber, gear chamber cover.Fluid power pressure lubrication assembly mainly is made up of the lubricant pipe parts.
Adopt said structure, transmission system is characterized in that each tooth normal module is 2.5, and pressure angle is 15 degree, and helix angle is 18 degree.This gear transmission running is steadily vibrated for a short time, and noise is light.The SAE spline is characterized in that its shaft extension form is an involute, and its parameter is: big footpath diameter is 18 millimeters of 17 ∽, and the path diameter is 15 millimeters of 14 ∽, and pressure angle is 30 degree, and the number of teeth is 10, diametral pitch 16/32.Fluid power pressure lubrication assembly communicates with the body main oil gallery by the lubricant pipe parts, and pair friction pair that link to each other with the gap bridge tooth of high pressure oil wherein carry out pressure lubrication and cooling, thereby improves the friction pair reliability and reduce noise.When this cover system advantage was to carry higher power output, good reliability, noise were low.

Embodiment is further described the utility model below in conjunction with accompanying drawing
As shown in Figure 1, the utility model PTO auxiliary power output system drives oil hydraulic pump gear (Z5) by crankshaft timing gear (Z1) by idle gear A (Z2), idle gear B (Z3), carrier gear (Z4).
Each gear parameter: crankshaft timing gear Z1=21, idle gear A Z2=31, idle gear B Z3=37, carrier gear Z4=28, oil hydraulic pump gear Z5=21; Each tooth normal module is 2.5, and pressure angle is 15 °, and helix angle is 18 °.Each gear system of coordinates: X1=19.475～19.525, Y1=66.975～67.025, X2=98.875～98.925, Y2=109.375～109.425, X3=166.575～166.625, Y3=56.275～56.325, X4=227.475～227.525, Y4=81.175～81.225.Its parameter of SAE spline is: big footpath diameter is 17.463 millimeters, and the path diameter is 14.465 millimeters, and pressure angle is 30 degree, and the number of teeth is 10, diametral pitch 16/32.
As shown in Figure 3: lubricant pipe parts (1) communicate with the body main oil gallery, high pressure oil wherein plays effect lubricated and cooling to gear transmission, bearing plate parts (2) change the screw-in length of adjusting screw, the axial clearance of may command tapered roller bearing 30206 (3), gap bridge tooth (11) drives oil hydraulic pump gear (6) and rotates, there is the SAE spline of ten teeth to be connected with oil hydraulic pump (8) at the one end, gear chamber (7) and gear chamber cover (4) shield whole device, and gear chamber Cover Gasket (5) plays the effect of sealing.
The utility model is not limited to above-mentioned mode of execution, and train of gearings is arranged same or similar, and the parameter of selecting all belongs within the utility model protection in the utility model scope.
