Abstract
The invention discloses a bearing seat of a carrier roller. The bearing seat of the carrier roller comprises an inner cylinder body and an outer cylinder body, wherein the inner cylinder body and the outer cylinder body are coaxially arranged, a reinforced rib is arranged between one end of the inner cylinder body and the inner wall of the outer cylinder body, a bearing installation groove is formed between an end portion inner ring of the outer cylinder body and the reinforced rib, a groove is formed in an outer ring of the outer cylinder body in the axial direction, a stopping ring is arranged at the other end of the inner cylinder body, the inner diameter of the stopping ring is smaller than that of the inner cylinder body, and a supporting rib is arranged in the inner wall of the stopping ring in the radial direction. The inner cylinder body, the outer cylinder body, the reinforced rib, the stopping ring and the supporting rib are formed by injection of materials such as high molecular weight polyethylene, plastics or nylon. The bearing seat of the carrier roller has the advantages of being reasonable in design, simple in structure, easy to machine, convenient to install, low in cost, strong in stability of the size, high in shock resistance, strong in practicability and easy to popularize and apply.
Description
Technical field
The present invention relates to a kind of carrying roller for the back-up belt transportation, relate in particular to a kind of supporting roller bearing seat.
Background technology
The bearing seat of tradition carrying roller adopts the metal material processing manufacturing to form mostly, weight is large, cost is high, resistance to abrasion and endurance life low, vibration damping, sound absorption, self lubricity, insulation and flame resistance can be relatively poor.At present, the supporting roller bearing seat of plastic material is arranged also, but due to complex structure, manufacturing process is loaded down with trivial details, cost is high, short causing in service life be difficult for applying.
Summary of the invention
The present invention is in order to solve weak point of the prior art, provide a kind of simple in structure, cost is low, the supporting roller bearing seat of long service life.
For solving the problems of the technologies described above, the present invention adopts following technical scheme: supporting roller bearing seat, the inner barrel and the outer cylinder body that comprise coaxial setting are provided with reinforced rib between one end of inner barrel and outer cylinder body inwall, form a bearing mounting groove between an end inner ring of outer cylinder body and reinforced rib.
The outer ring of described outer cylinder body is provided with groove vertically.
The other end of described inner barrel is provided with barrier ring, and the internal diameter of barrier ring is less than the internal diameter of inner barrel.
The inwall of described barrier ring radially is provided with brace rod.
Described inner barrel, outer cylinder body, reinforced rib, barrier ring and brace rod are by ultra-high molecular weight polyethylene, plastics or nylon material injection mo(u)lding.
Adopt technique scheme, the present invention adopts particular manufacturing craft once injection molded, and it is lightweight, simple installation, avoid maintenance, acid and alkali-resistance, high temperature resistant, has simultaneously cast-iron chock commonly used and ram axle damping shock resistance that bearing does not have.The outer ring of outer cylinder body arranges groove vertically, namely outer cylinder body surface adopt convex-concave structure to increase and carrying roller cylinder between friction force; Be hollow structure and design reinforced rib between inner barrel and outer cylinder body, make it not affect the pressure that it bears when saving material; When barrier ring and brace rod are used for fixing carrying roller and press-fit the steel axle in the bearing seat up and down, the left and right action radius, make to press-fit more conveniently, quick, improved production efficiency.
The present invention is reasonable in design, simple in structure, be easy to processing, be convenient to install, cost is low, dimensional stability is strong, shock resistance is high, practical, is easy to apply.

Fig. 2 is the upward view of Fig. 1.
The specific embodiment
As depicted in figs. 1 and 2, supporting roller bearing seat of the present invention, the inner barrel 1 and the outer cylinder body 2 that comprise coaxial setting, be provided with reinforced rib 3 between one end of inner barrel 1 and outer cylinder body 2 inwalls, reinforced rib 3 is disposed radially some, forms a bearing mounting groove 4 between an end inner ring of outer cylinder body 2 and reinforced rib 3.The outer ring of outer cylinder body 2 is provided with groove 5 vertically, and groove 5 evenly arranges some along the outside face of outer cylinder body 2.The other end of inner barrel 1 is provided with barrier ring 6, and the internal diameter of barrier ring 6 is less than the internal diameter of inner barrel 1.The inwall of barrier ring 6 radially is provided with some brace rods 7.Inner barrel 1, outer cylinder body 2, reinforced rib 3, barrier ring 6 and brace rod 7 are by ultra-high molecular weight polyethylene, plastics or nylon material injection mo(u)lding.Form toroidal cavity 8 between inner barrel 1 and outer cylinder body 2, in the situation that guarantee wall thickness, groove 5 and toroidal cavity 8 arrange suitable pattern draft.
The present invention adopts the non-metallic material integrated injection moldings such as ultra-high molecular weight polyethylene, plastics, nylon or ABS to form, and the diametral load the when weight of the whole bearing of support and rotor rotate provides the lubrication condition to bearing.
ABS resin is a kind of blend, is acrylonitrile-butadiene-styrene copolymer, English name Acrylonitrile-butadine-styrene (being called for short ABS), and this three's ratio is 20:30:50 (fusing point is 175 ℃).As long as the size of its three's of change ratio, chemical combination method, particle, just can produce a series of kinds with different strength under shocks, flow characteristic, as the composition of butadidenne is increased, its strength under shock can be improved, but hardness and flowing power will reduce, and intensity and resistance to effect of heat become and can reduce.
ABS is synthetic by acrylonitrile, butadidenne and three kinds of chemical monomers of styrene.Every kind of monomer all has different qualities: acrylonitrile has high strength, heat stability and chemical inertness; Butadidenne has toughness, impact property; Styrene has easy processing, best bright finish and high strength.On form, ABS is non-crystalline material.The polymerization of middle monomer has produced the terpolymer with two-phase, and one is the continuous phase of styrene-acrylonitrile, and another is the poly-butadiene rubber discrete phase.The characteristic of ABS depends primarily on the ratio of three kinds of monomers and the molecular structure in two-phase.This just can have very large alerting ability on product design, and has produced thus the ABS material of hundreds of different qualities on market.The material of these different qualities provides different characteristics, for example therefrom waits until high impact resistance, degree of finish from low to high and high temperature torsion characteristic etc.The ABS material has superpower workability, appearance characteristics, low creep properties and excellent dimensional stability and very high impact strength.
Compare with the bearing seat of metallic material, the present invention is lightweight, easy maintenance.Chemical inertness is good, and resistance to abrasion and endurance life are high, and has vibration damping, sound absorption, self lubricity, insulation and flame resistance.But thermal expansion coefficient is large, and coefficient of thermal conductivity is low, and hygroscopic property is larger, and intensity and dimensional stability are not as metal.Be used for the place that speed is not high or thermal diffusivity is good, operating temperature should not surpass 65 ℃, and instantaneous operating temperature is no more than 80 ℃.
