Abstract

The invention discloses a high temperature filling-slot-free full ball bearing which comprises an inner ring, an outer ring and a rolling body. The full ball bearing is characterized in that the bearing is not provided with a retainer; the inner ring comprises a first half inner ring and a second half inner ring, and the first half inner ring and the second half inner ring form two half inner rings in a combination manner; the bearing also comprises a tight sleeve, the two half inner rings are fixed into a whole through the tight sleeve, the tight sleeve is arranged on an inner circle side surface that a mesopore of the two half inner rings contains the two half inner rings and is fixedly connected with the two half inner rings; and the depth of a rolling groove in the middle of the inner circle wall surface of the outer ring is 1/8-1/2 of the diameter of the rolling body, and the depth of the rolling groove in the middle of the excircle wall surface is 1/8-1/2 of the diameter of the rolling body. The high temperature filling-slot-free full ball bearing is consistent to the physical dimension of the similar standard bearing, can suffer from radiation or transmit high temperature or spontaneously generates high temperature when the external heating is performed, can resist heavy load, impulsion under the severe work environments such as such as dust, foul gas or foul solution invasion and the like, can not use a lubricant, is abrasion-proof, oxidation-protection, corrosion-proof, and has a long service life.

Description

The full ball bearing of a kind of high temperature arming segment mouth

Technical field

The present invention relates to bearing, specifically is the full ball bearing of a kind of high temperature arming segment mouth.

Background technique

Bearing is applied in the different piece of various device; The prior standard bearing, its structure comprises outer ring, inner ring, rolling element and roller holder, interior week is equipped with raceway in the periphery of inner ring and outer ring; When inside and outside circle rolls relatively; Rolling element promptly rolls in the raceway of inside and outside circle, and inside and outside circle is separated by retainer, avoids the phase mutual friction.

The bearing of this structure, when outside many, using in the occasion of heating or spontaneous high heat, can not use basically or working life extremely short, be prone to cause the heavy losses of human, financial, and material resources.

Summary of the invention

The objective of the invention is deficiency to existing technology; And providing a kind of and similar standard rolling bearing boundary dimension consistent, raying or conduction high temperature or spontaneous high heat in the time of adapting to outer the heating have abominable working environment such as dust, dirty gas or soiling solution invasion and attack; Can resist heavy duty, impact; Can be without lubricator, wear-resisting anti-oxidation anticorrosive, the arming segment mouth of long service life is expired ball bearing.

The objective of the invention is to realize through following technological scheme:

The full ball bearing of a kind of high temperature arming segment mouth comprises inner ring, outer ring and rolling element, and different with existing technology is: this bearing is not established retainer; Described inner ring comprises the first half inner rings and the second half inner rings, and the first half inner rings and the second half inner rings are combined to form two half inner rings; This bearing also comprises tight cover, and two half inner rings fix as one through tight cover.

The described mesopore that tightly is set on two half inner rings contains the inner round wall face of two half inner rings, and is fixedly connected with two half inner rings.

The degree of depth of the rolling groove of the inner round wall face intermediate portion of said outer ring is the 1/8-1/2 of rolling element diameter, and the degree of depth of the rolling groove of the cylindrical wall intermediate portion of said two half inner rings is the 1/8-1/2 of rolling element diameter.

Rolling element is steel ball and full dress; Itself and two each ditch side of half inner ring are a bit, the outer ring bottom of trench a bit is at 3 and contacts; Can improve load carrying power greatly, can as the spheroid of conventional bearing, inner ring, outer ring, retainer, not be prone to deform and kill in the high temperature, so that damage of bearings; Roll in the rolling groove of the rolling groove that steel ball completely is installed on the outer ring and two half inner rings, just retainer need not be set, can not drop out during work outside the circle, joining material and heat treatment technology thereof, this bearing can high temperature resistant 300-800 ℃.

The present invention is consistent with similar standard rolling bearing boundary dimension, and raying or conduction high temperature or spontaneous high heat have abominable working environment such as dust, dirty gas or soiling solution invasion and attack in the time of adapting to outer the heating; Can resist heavy duty, impact; Can be without lubricator, wear-resisting anti-oxidation anticorrosive, long service life.

Description of drawings

Fig. 1 is embodiment's a cross-sectional view;

Fig. 2 is embodiment's a structural representation.

Among the figure, 1. outer ring 2. rolling elements 3. the first half inner rings 4. the second half inner rings 5. tightly overlap.

Embodiment

Below in conjunction with accompanying drawing and embodiment content of the present invention is further described, but is not qualification of the present invention.

Embodiment:

Shown in Figure 2 like Fig. 1, the full ball bearing of a kind of high temperature arming segment mouth comprises inner ring, outer ring 1 and rolling element 2, and this bearing is not established retainer; Inner ring comprises that the first half inner rings 3 and the second half inner ring 4, the first half inner rings 3 and the second half inner rings 4 are combined to form two half inner rings; This bearing also comprises tight cover 5, and two half inner rings fix as one through tight cover 5.

Tight cover 5 is arranged on the inner round wall face of two half inner rings of mesopore containing of two half inner rings, and is fixedly connected with two half inner rings.

The degree of depth of the rolling groove of the inner round wall face intermediate portion of outer ring 1 is the 1/8-1/2 of rolling element diameter, and the degree of depth of the rolling groove of the cylindrical wall intermediate portion of two half inner rings is the 1/8-1/2 of rolling element diameter.

Rolling element 2 is steel ball and full dress; Itself and two each ditch side of half inner ring are a bit, outer ring 1 bottom of trench a bit is at 3 and contacts; Can improve load carrying power greatly, can as the spheroid of conventional bearing, inner ring, outer ring, retainer, not be prone to deform and kill in the high temperature, so that damage of bearings; Completely adorn in the rolling groove of rolling groove that steel ball is installed on outer ring 1 and two half inner rings and roll, just retainer need not be set, can not drop out during work outside the circle, joining material and heat treatment technology thereof, this bearing can high temperature resistant 300-800 ℃.
