Abstract

The invention relates to a deep groove ball bearing guided by a steel ball, and relates to the field of bearings. Compared with conventional deep groove ball bearings, the deep groove ball bearing guided by the steel ball has the following prominent advantages and positive effects: a cage of the deep groove ball bearing is guided by the steel ball and is composed of two identical half-cages; the shape of a pocket of each cage is a semi-sphere, with the sphere center positioned on one side of an end face; and the two half-cages are connected through rivets to form a spherical pocket. Lubricating medium can enter easily by enlarging the gap between ring ribs and the outer diameter or the inner diameter of the cage, so that accurate guidance of rolling bodies can be realized; frication and temperature rising of the bearing can be reduced; good running quality of the bearing is guaranteed; service life is prolonged; and reliability of the bearing is improved.

Description

A kind of deep groove ball bearing of steel ball guiding

Technical field

The present invention relates to a kind of deep groove ball bearing of steel ball guiding, it belongs to field of bearings.

Background technique

Along with the continuous evolution of the human civilization high speed development with science and technology, bearing industry is from small and weak starting, difficult foundation; Keen competition; Tortuous development, by several wife and children factory in the past develop into now spread all over the world, a year sales volume volume reaches 30,000,000,000 dollars scale, obtained astonishing achievements.Usually press the difference of rolling element kind in the bearing, it is divided into ball bearing and roller bearing, and be divided into radial bearing and thrust-bearing by the main action direction that bearing can bear load.Deep groove ball bearing belongs to a series of rolling bearing, and zanjon ball brass retainer form commonly used is the two halves riveted structure, and this structure is generally outer ring or inner ring rib guiding; The form in pocket hole is cylindrical; Because the retainer guide clearance of this structure is little, lubricant medium is difficult to get into, when running up; The lasso rib is prone to produce friction with retainer external diameter or internal diameter, impels retainer to damage in early days.The friction back produces great amount of heat, makes lasso and retainer generation thermal expansion, makes the bearing locking when serious, even bearing and axle sintering are in the same place, and has influenced the normal operation of equipment.

Summary of the invention

In view of the defective that prior art exists, the objective of the invention is to provide a kind of deep groove ball bearing of steel ball guiding, it adopts the brass retainer to adopt the steel ball guiding; Form by two half identical retainers; Reach the gap of strengthening lasso rib and retainer external diameter or internal diameter, made lubricant medium be prone to get into, can realize the accurate guiding of rolling element; Reduced the friction and the intensification of bearing, guaranteed to have good riding quality at bearing.

Be the realization above-mentioned purpose, the deep groove ball bearing of a kind of steel ball guiding of the technical solution that the present invention adopted, it is made up of outer ring, retainer, steel ball, inner ring and rivet; Be respectively equipped with raceway on outer ring and the inner ring, steel ball is loaded in the pocket hole of retainer, and retainer is between inner ring and outer ring; It is characterized in that: retainer brass retainer adopts the steel ball guiding, is made up of two half identical retainers, and the pocket hole shape of each retainer is a hemisphere, and the centre of sphere is on the end face of a side, and two and half retainers connect with rivet, form spherical pocket hole.

The present invention compared with prior art; Have following outstanding advantage and good effect: its retainer adopts the steel ball guiding; Be made up of two half identical retainers, the pocket hole shape of each retainer is a hemisphere, and the centre of sphere is on the end face of a side; Two and half retainers connect with rivet, form spherical pocket hole.The gap that it strengthens lasso rib and retainer external diameter or internal diameter makes lubricant medium be prone to get into, and can realize the accurate guiding of rolling element; The friction and the intensification of bearing have been reduced; Guarantee to have good riding quality, life-saving, the reliability of raising bearing at bearing.

Embodiment

In order further to understand the deep groove ball bearing of this steel ball guiding, explain as follows in conjunction with Fig. 1, Fig. 2 and Fig. 3:

It is made up of outer ring 1, retainer 3, steel ball 2, inner ring 4 and rivet 5; Be respectively equipped with raceway on outer ring 1 and the inner ring 4, steel ball 2 is loaded in the pocket hole of retainer 3, and retainer 3 is between inner ring 4 and outer ring 1; It is characterized in that: retainer 3 brass retainers adopt steel ball 2 guiding, are made up of two half identical retainers 3, and the pocket hole shape of each retainer 3 is a hemisphere, and the centre of sphere is on the end face of a side, and two and half retainers connect with rivet 5, form spherical pocket hole.

Claims

1. the deep groove ball bearing of steel ball guiding, it is made up of outer ring, retainer, steel ball, inner ring and rivet; Be respectively equipped with raceway on outer ring and the inner ring, steel ball is loaded in the pocket hole of retainer, and retainer is between inner ring and outer ring; It is characterized in that: retainer brass retainer adopts the steel ball guiding, is made up of two half identical retainers, and the pocket hole shape of each retainer is a hemisphere, and the centre of sphere is on the end face of a side, and two and half retainers connect with rivet, form spherical pocket hole.
