The seal lip is an annular slice, the annular area, close to the circle center, of the annular slice is clamped by the static seal ring and the locating sleeve, and the edge of the annular slice is tightly attached to the sealing face of the wear-proof ring. The cage shoe roller is long in service life, convenient to lubricate, low in maintenance cost, and capable of improving production efficiency.
Description
Technical field
The invention belongs to technical field of coal mine equipment, relate to a kind of rolling cage shoe be used on cage, skip bucket or bob-weight, be specifically related to the cage shoe roller of a kind of sealing property improvement.
Background technology
Rolling cage shoe is used as track adjusting wheel when cage, skip bucket or bob-weight are elevated along steel guide, and leads and buffer action for they provide, and is very important parts on lifting container.
The rolling cage shoe that tradition uses comprises wheel hub, anchor shaft, bearing and sealing member etc.;
Wheel hub has cylindrical bore, and by bearing, the endoporus of wheel hub and the outside face of anchor shaft form revolute pair, by rocker and energy disperser, anchor shaft is fixed on lifting container, sealing member is used for stopping the dust, trickle etc. in external environment, prevents from entering bearing, to extend the service life of bearing.
The sealing member that tradition uses, the oil sealing of most use contact sealing or rubber ring etc., these packing elements are once wearing and tearing, then extraneous dirt or trickle are easy to enter in bearing roller, bearing is easy to damage, and causes rolling cage shoe rapid failure, affects production and proceed, also may occur that part comes off, fall to the major accident in shaft bottom, problems demand solves.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, adapt to reality need, the cage shoe roller that a kind of sealing property improves is provided.
The present invention is achieved through the following technical solutions:
A kind of cage shoe roller of sealing property improvement, it is characterized by and comprise wheel hub, anchor shaft, bearing, wheel hub has cylindrical bore, passes through bearing, the endoporus of wheel hub and the outside face of anchor shaft form revolute pair, have a set of labyrinth gland and a set of sealing lip-flow ring sealing arrangement outside bearing; Labyrinth packing is side seal, be made up of stationary seal ring and rotary packing ring, stationary seal ring and anchor shaft flush fit, rotary packing ring and baffle ring flush fit, flush fit between baffle ring and wheel hub, lubricating oil, grease or pollutants can not pass through from tolerance clearance, dentation seal ring is all provided with above stationary seal ring, rotary packing ring, tooth and tooth are mutually engaged and form a series of throttle clearance and expansion cavity, dust or lubricating grease can produce throttling effect when the gap by tortuous labyrinth, thus play sealing function.Because stationary seal ring and rotary packing ring are without solid contact, there is no abrasion, and allowed het expansion, so service life is longer, can not damages easily, decrease maintenance cost, improve production efficiency.
Sealing lip-flow ring sealing is by sealing lip, flow ring and locating bush composition, flow ring external cylindrical surface and baffle ring flush fit, lubricating oil, grease or pollutants can not pass through from tolerance clearance, sealing lip is an annular arrangement thin slice, from the circular annular region close to the center of circle by stationary seal ring and locating bush clamping tightly, outer rim place is closely close together by the sealing surface of elastic force and flow ring, form sealing surface, even if also do not leave when rotated, this a pair sealing surface is divided into both sides space, wherein the dust of side or grease want to move to opposite side needs to overcome the larger elastic force of sealing lip, more difficult, so can sealing function be played.Sealing lip and flow ring all select the material that friction coefficient is little and wear-resisting, such as steel, corrosion-resistant steel, copper or engineering plastics, so the heat produced is few, also not fragile.
For the ease of lubrication, centre hole is provided with in one end of anchor shaft, the transversal surface of anchor shaft is provided with transverse holes, transverse holes and centre hole connect, the outlet of transverse holes is led between two bearings, within the endoporus of wheel hub, the mouth place of centre hole is provided with negative thread, and lubricating cup is connected on anchor shaft by negative thread.Oil gun is used to be inserted in the mouth of lubricating cup, play butter to the inside, then butter enter between two bearings by centre hole and transverse holes, region within the endoporus of wheel hub, then flow to the rolling body of bearing when this space is filled up, thus lubricating bearings, effectively can extend the service life of bearing.
Beneficial effect of the present invention: long service life, lubrication are convenient, maintenance cost reduces, production efficiency improves.

Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is further described:
Embodiment: see Fig. 1 to Fig. 2.
As shown in Figure 2, bearing 1 has been installed in the hole at wheel hub 7 two ends respectively, and the endoporus of bearing 1 coordinates with the external cylindrical surface of anchor shaft 8, has a set of sealing lip-flow ring sealing arrangement outside bearing 1; Labyrinth packing is side seal, be made up of stationary seal ring 5 and rotary packing ring 3, stationary seal ring 5 and anchor shaft 8 flush fit, rotary packing ring 3 and baffle ring 10 flush fit, flush fit between baffle ring 10 and wheel hub 7, lubricating oil, grease or pollutants can not pass through from tolerance clearance, stationary seal ring 5, rotary packing ring 3 are all provided with dentation seal ring above, tooth and tooth are mutually engaged and form a series of throttle clearance and expansion cavity, dust or lubricating grease can produce throttling effect when the gap by tortuous labyrinth, thus play sealing function.Because stationary seal ring 5 and rotary packing ring 3, without solid contact, so do not have abrasion, and have allowed het expansion, so service life is longer, can not damages easily, decrease maintenance cost, improve production efficiency.
