Description

Widened Tapered Roller Bearings for Stone Saws

technical field

The utility model relates to a bearing, in particular to a widened tapered roller bearing used for a stone sawing machine.

Background technique

Tapered roller bearings are separable bearings, and the inner and outer rings of the bearing have tapered raceways. This type of bearing is divided into different structural types such as single row, double row and four row tapered roller bearings according to the number of rows of rollers installed. Single row tapered roller bearings can bear radial loads and axial loads in one direction. When the bearing bears radial load, an axial component force will be generated. At present, bearings in the cutting industry are important components in stone sawing machines. They are installed in pairs on the main shaft and will be affected by high loads and vibrations during use. Usually, tapered roller bearings are used to withstand radial forces, but Often limited by the standard design dimensions, multiple sets of bearings are used to meet the load-bearing requirements, and installation and maintenance are very difficult.

Utility model content

The purpose of this utility model is to provide a widened tapered roller bearing for stone sawing machines in order to overcome the above-mentioned defects in the prior art.

The purpose of this utility model can be achieved through the following technical solutions:

A widened tapered roller bearing for a stone sawing machine, characterized in that it includes an outer ring, a bearing retainer and an inner ring arranged sequentially from outside to inside, and the groove of the bearing retainer is also provided with Tapered rollers, the tapered rollers roll in the tapered raceway formed by the cooperation of the inner ring raceway outside the inner ring and the outer ring raceway inside the outer ring. The outer ring, inner ring and tapered roller of the bearing All adopt widening structure, which increases the width of the outer ring, inner ring and the total width after assembly, expands the range of bearing force in the radial direction, and improves the load-bearing performance of the bearing.

There are multiple tapered rollers, which are evenly distributed in the grooves of the bearing holder.

The tapered roller adopts a logarithmic curve convexity modification structure.

The outer ring is lengthened by 20-30 mm.

The inner ring is lengthened by 20-30mm.

After the assembly, the bearing is lengthened by 20-30mm.

Compared with the prior art, the utility model has the following advantages:

1. Strong bearing capacity: Due to the use of widened inner and outer rings and rollers, the radial force and axial force that the bearing can withstand are greatly improved, thereby increasing the bearing load capacity and improving the impact resistance of the bearing.

2. Long service life, the roller adopts logarithmic curve convexity modified roller, which prolongs the service life.

Description of drawings

Among them, 1. Outer ring, 2. Inner ring, 3. Bearing retainer, 4. Tapered roller.

Detailed ways

The utility model will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

Example 1

As shown in Figure 1, a widened tapered roller 4 bearing for a stone sawing machine includes an outer ring 1, a bearing holder 3 and an inner ring 2 arranged in sequence from outside to inside, and the bearing holder 3 There are also tapered rollers 4 in the groove, and the tapered rollers 4 roll in the tapered raceway formed by the cooperation between the inner ring 2 raceway outside the inner ring 2 and the outer ring 1 raceway inside the outer ring 1 , the outer ring 1, inner ring 2 and tapered roller 4 of the bearing adopt a widened structure, which increases the width of the outer ring 1, the width of the inner ring 2 and the total width after assembly, and expands the radial bearing force range, which improves the load-carrying performance of the bearing.

There are multiple tapered rollers 4 and they are evenly distributed in the groove of the bearing holder 3 . The tapered roller 4 adopts a logarithmic curve convexity modification structure. The outer ring 1 is lengthened by 25mm. The inner ring 2 is lengthened by 25mm. After the assembly, the bearing is lengthened by 25mm.

Example 2

The outer ring 1 is lengthened by 20mm. The inner ring 2 is lengthened by 20mm. After the assembly, the bearing is lengthened by 20mm. Others are the same as embodiment 1.

Example 3

The outer ring 1 is lengthened by 30mm. The inner ring 2 is lengthened by 30mm. After the assembly, the bearing is lengthened by 30mm. Others are the same as embodiment 1.
