Abstract
The invention discloses a crusher gear static pressure bearing mechanism which comprises a static pressure bearing ring. The static pressure bearing ring is of an annular shape, the inner hole of the static pressure bearing ring is in a stepped shape, and dowel holes are formed in the stepped face of the inner hole in the circumferential direction. An annular oil storage tank is formed in the end face of a small hole diameter end of the static pressure bearing ring in the circumferential direction, the end face of the small hole diameter end of the static pressure bearing ring is divided into an inner ring face and an outer ring face through the annular oil storage tank, and a plurality of radial oil discharging tanks communicated with the annular oil storage tank are uniformly distributed in the inner ring face and the outer ring face in the circumferential direction respectively. According to the crusher gear static pressure bearing mechanism, the operating principle of hydrostatic static pressure bearing is utilized, namely a continuous and stable fluid pressure source is directly injected into a bearing face at the lower end of the static pressure bearing, fluid with definite pressure is supplied between friction surfaces, loads are borne with the help of static pressure of the fluid, gluing and fast abrasion of a bevel gear static pressure bearing piece and a backup washer are effectively prevented, and thus stability and reliability of transmission of a bevel gear are guaranteed.
Description
Technical field
The invention belongs to hydro cone-crusher and hydraulic rotary crusher technical field, relate in particular to a kind of disintegrator gear hydrostatic support mechanism.
Background technique
As everyone knows, in large hydraulic circular cone (cycle) disintegrator, spiral bevel gear (hereinafter to be referred as umbrella gear) is the important transfer mechanism of crusher in crushing power, for between the supporting surface that prevents umbrella gear umbrella gear in the process of running up and supporting element because gummed or Fast Wearing occur in friction, often need the large and very little structure of frictional force of a kind of bearing capacity, adapt to dynamic load and the large load working condition of crusher members.The disintegrator hydrostatic support is the important support mechanism of umbrella gear, traditional hydrostatic support is near the trapezoidal junction plane of inner circle area band boss and the lower end surface that some straight pins are fixed in umbrella gear by upper-end surface, main by the lubricated hydraulic fluid port from the disintegrator upper mechanism, inject lubricant oil, the umbrella gear transfer mechanism that then is delivered to successively from top to bottom bottom by structure interval is lubricated.This fuel feeding lubricating system is because the fuel feeding route is long; lubricated scope is wide; when lubricant oil arrives umbrella gear hydrostatic support zone; fuel delivery and charge oil pressure are often unstable; in case disintegrator bears suddenly large impulsive load, this mechanism's vibration absorption ability is poor, can't protect preferably large small gear and supporting member; and the supporting member wearing and tearing are accelerated, tile kilning shutdown phenomenon easily appears when serious.Although offered annular oil storage tank and oil unloading trough in the supporting member lower end surface, be subjected to the impact of hydraulic oil fuel system, still can't provide and stablize lasting oil film protection.Hydrostatic support adopts trapezoidal junction plane and the fixing mode of some straight pins simultaneously, is also bringing certain difficulty aspect processing and installation, and practicability and Economy are poor.
Summary of the invention
In order to address the above problem, the purpose of this invention is to provide a kind of disintegrator gear hydrostatic support mechanism, utilize the working principle of liquid static-pressure support, namely to the supporting surface of hydrostatic support lower end, directly inject the fluid pressure source of continous-stable, to between friction surface, supplying with the fluid of certain pressure, static pressure by fluid is carried out bearing load, can prevent effectively that umbrella gear hydrostatic support spare and supporting bead from gummed and Fast Wearing occurring, thereby guarantee bevel geared stability and reliability.
For achieving the above object, patent of the present invention has adopted following technological scheme:
A kind of disintegrator gear static pressure supporting mechanism, comprise the hydrostatic support ring, and the hydrostatic support ring is a ring structure, and endoporus is step-like, on the step surface of endoporus, offers in the circumferential direction of the circle positioning pin hole; On the small aperture end end face of hydrostatic support ring, offer in the circumferential direction of the circle annular oil storage tank, the annular oil storage tank is separated into inner ring surface and outer ring surface by the small aperture end end face of hydrostatic support ring, on inside and outside anchor ring, be laid with respectively in the circumferential direction of the circle the radially oil unloading trough that some and described annular oil storage tank is connected, and the radially oil unloading trough arrangement interlaced with each other on inner ring surface and outer ring surface.
Further, the cross section of described annular oil storage tank is wedge shape.
Further, the cross section of described radially drain pan is wedge shape.
Owing to adopting technique scheme, the present invention has following superiority:
1, hydrostatic support ring of the present invention when mounted, the end face that has oil storage tank and oil unloading trough on it be fixed in the disintegrator underframe and match and contact with supporting bead between oil cylinder, and formation hydrostatic support fitting surface, by the oil hole on supporting bead, inject high-voltage oil liquid, make between the fitting surface of hydrostatic support ring and supporting bead, to form oil film and it is directly contacted, avoided two friction pairs directly to produce contact and caused that the situation that the hydrostatic support wearing and tearing were even lost efficacy occurs.
2, hydrostatic support ring of the present invention annular oil storage tank and inside and outside under the effect of the oil unloading trough that is interspersed, can make to support working surface works under the encirclement of comprehensive, continuous and stable pressure oil, this structure makes the oil slick thickness of each oil groove substantially equal, therefore kinematic accuracy is high, oil film rigidity is large, damping capacity is good, can effectively suppress the concussion of oil film during high speed, thereby has improved impact resistance and the bearing capacity of umbrella gear;
3, on the hydrostatic support ring, annular oil storage tank and oil unloading trough adopt the wedge-shaped structure design, can form throttling to fluid, make the fluid of oil groove that point pressure be arranged a little, are conducive to like this make the pressure oil of whole working surface to be in all the time flowing state, help heat radiation.Simultaneously, when the load on acting on hydrostatic support changed suddenly, the oil groove face can allow system settle out very soon, and namely dynamic performance is good.
4, this gear hydrostatic support mechanism can be in all the time under the oil lubrication state and work, and can not produce wearing and tearing while normally using, and precision stability is good, reliable performance, long service life, installation, easy maintenance.
