Description
Technical field
The utility model relates to a kind of every disk hole, and especially a kind of axle distributing cycloid hydraulic motor, every dish compound oil through, also relates to its processing method simultaneously, belongs to hydraulic transmission technology field.
Background technique
Cycloid hydraulic motor is conventional fluid pressure drive device, is also to realize the conventional hydraulic pressure execution device that hydraulic energy converts function to.Cycloid hydraulic motor is a kind of low-speed big torque motor, has the advantages such as volume is little, specific power density is large, efficiency is high, speed range is wide, is thus widely applied.
The flow-distribution mechanism of axle distributing cycloid hydraulic motor is positioned at the radially direct varying number flow duct of the pintle of the output shaft cooperatively interacted and the assignment hole of body shell, during motor operations, flow-distribution mechanism makes liquid entering hole engage chamber with the expansion of cycloidal pin wheel set to be communicated with, and the contraction chamber of cycloidal pin wheel set is communicated with refluxing opening.As a result, after pressured fluid enters body shell or bonnet from liquid entering hole, enter the expansion engagement chamber that cycloidal pinion engaged pair is formed, its volume is constantly expanded, the contraction that cycloidal pinion engaged pair is formed simultaneously is engaged liquid in chamber and is then refluxed from refluxing opening; In the process, the rotor of cycloidal pinion engaged pair is expanded engagement chamber and shrinks the pressure difference engaging chamber and orders about rotation, and this is rotated through couple axle and be delivered to output shaft output, thus realizes the conversion of hydraulic energy to mechanical energy.Meanwhile, flow-distribution mechanism (axle valve) is also by couple axle driven rotary, and the continuous switching connected state gone round and begun again, makes transfer process be continued.Like this, motor just can continuous print output torque.
According to the applicant understood, flow-distribution mechanism and the edge pillar of existing axle distributing cycloid hydraulic motor turn between stator pair by linking up every coiling, oil through every dish is connected with the fluid through hole of flow-distribution mechanism, for the waist shaped hole that concentric circle holes or concentric semicircles hole and link bolt hole are linked up, this class formation is due to the position limitation of the fluid through hole of flow-distribution mechanism, the gap of the assignment hole of itself and flow-distribution mechanism is less, cause the assignment hole gap every dish oil through and flow-distribution mechanism little, be unfavorable for preventing fluid seepage, and cause hydraulic damping owing to limiting every the oil through of dish.
Summary of the invention
The utility model object is: for above prior art Problems existing, a kind of axle distributing cycloid hydraulic motor oil through is proposed, compound oil through every dish increases and an assignment hole gap, improves its processing technology, improves the overall performance every dish manufacturing efficiency and product.
In order to achieve the above object, claimant is by the analysis of Integral Structure to axle distributing cycloid hydraulic motor, especially flow-distribution mechanism, edge pillar turns stator movement pair and studies every the position relationship coiling oil through, find out the weak link of existing structure, application new material new process, keeping under existing overall motor boundary dimension and the constant prerequisite of overall structure, proposing following the technical solution of the utility model is: the duct on dish disc with two round different annular spread that distribute of axle distributing cycloid hydraulic motor, outer shroud duct is bolt connecting passage, inner ring duct is the oil through of motor oil passage, its improvements are, a kind of axle distributing cycloid hydraulic motor oil through, described oil through is being made up of the duct of the different key element of both ends of the surface on dish, one end is by two sections of circular arcs, the other end is made up of four arcs, different ducts, two ends rounding off, form oil through one end described in the overall compound oil through of fluid to be communicated with the oil through of flow system, the other end with turn stator pair engage cavity connects.
Described two sections of circular arcs every the upper oil through of dish form by with the isocentric circular arc that is the center of circle every disk center and the circular arc of circular hole that intersects with it, and the described four arcs every the upper oil through of dish forms by with the symmetrical two ends circular arc of two isocentric circular arc that are the center of circle every disk center and circular hole crossing with it.
Two sections of circular arcs of described one end by with the isocentric circular arc that is the center of circle every disk center with four arcs by being same circular arc with the small arc-shaped in two isocentric circular arc that are the center of circle every disk center.
Described compound oil through covers the oil through of flow system completely, and described compound oil through is positioned at bore of stator maximum position.
Above technological scheme is further improved: described every dish compound oil through with being shaped by powder metallurgical technique every dish is disposable.
With the axle distributing cycloid motor of prior art every coiling structure compared with manufacturing process, the logical pasta increased after above-mentioned modified node method of the present utility model every dish amasss, and the gap at the flow-distributing valve engagement axis hole place of coaxial distributing construction, reduce possible leakage, reduce the pressure loss, improve the efficiency of product, change processing technology, adopt means of a powder metallurgy technique, raise the efficiency, save material, thus provide cost savings.
