Abstract
A kind of ultra-large type Biserial cylindrical roller bearing, including roller, inner ring, outer ring and retainer, the retainer are independent split type structure, and two row rollers, which are respectively provided between a retainer, two retainers, has gap.Retainer uses independent split type structure, suitable for frivolous serial bearing, gap can store certain lubricant between two retainers, in bearing rotation process, two retainer independent operations improve bearing operation flexibility, when avoiding two row rolling element asynchronous runnings, rolling element extrudes the shearing force produced to retainer pawl, it is ensured that the intensity of retainer during bearing high-mechanic high rotating speed, and bearing accuracy, rotating speed, lubricity, flexibility of revolution, limit speed and run stability are improved again.
Description
Technical field
The utility model is related to a kind of ultra-large type Biserial cylindrical roller bearing, belongs to technical field of bearings.
Technical background
As the constantly progressive and national life requirement of China's science and technology is improved constantly, mechanical field large-scale precision lathe also by
Walk and researched and developed to " high, precision and frontier " direction, it is desirable to possess high rotating speed, high accuracy, long-life for its supporting bearing and carry energy greatly
Power.Meanwhile, it is that large-scale precision lathe is supporting compared with middle heavy serial bearing for advocating for response national " energy-conserving and environment-protective "
The advantage of the frivolous serial bearing of high-quality is just highlighted, and it both can guarantee that high accuracy, long-life, large bearing capacity, but also with more
High rotating speed, smaller volume, higher energy-conservation sexual clorminance.But because frivolous serial bearing is yielding, to produce Bearing with high properties,
There is sizable difficulty in structure design and process of manufacture.
The content of the invention
Based on above-mentioned problem, the utility model provides the ultra-large type Biserial cylindrical roller bearing that a kind of external diameter is more than 800mm,
Including roller, inner ring, outer ring and retainer, the retainer is independent split type structure, and two row rollers are respectively provided with a guarantor
Holding has gap between frame, two retainers.The retainer is unilateral prong type cage, and two retainers are without the one of pawl
Side is adjacent.The roller bus has convexity.The bearing inner ring interior diameter is truncated cone-shaped.Set on the bearing inner race and outer ring
Hole for hoist.The bearing outer ring is split outer ring.
The beneficial effects of the utility model are：Retainer uses independent split type structure, it is adaptable to frivolous serial bearing, two
Gap can store certain lubricant between retainer, in bearing rotation process, two retainer independent operations, improve bearing fortune
Turn flexibility, it is to avoid during two row rolling element asynchronous runnings, rolling element extrudes the shearing force produced to retainer pawl, it is ensured that axle
The intensity of retainer when holding high-mechanic high rotating speed, improve again bearing accuracy, rotating speed, lubricity, flexibility of revolution, limit speed and
Run stability.
Brief description of the drawings
Fig. 1 is bearing arrangement partial schematic diagram,
In figure：1st, outer ring, 2, inner ring, 3, retainer, 4, roller, 5, hole for hoist.
Embodiment
A kind of external diameter is 1805mm, and appearance and size is 1500mm × 1805mm × 300mm ultra-large type double-row cylindrical roller
Bearing, including roller 4, inner ring 2, outer ring 1 and retainer 3, retainer 3 are independent split type structure, and two row rollers 4 are respectively provided with
There is gap between gap, two retainers 3 can store certain lubricant, retainer between one retainer 3, two retainers 3
For unilateral prong type cage, two retainers are adjacent without the side of pawl, and retainer pawl length is by calculating most
Short size, can ensure retainer intensity to greatest extent, and save copper product as far as possible, it is ensured that bearing assembling is smoothed out.
The bus of roller 4 has convexity, it is to avoid during bearing high-mechanic, the edge of roller 4 it is excessive to raceway pressure and produce stress concentration,
Ensure ultra-large type loading bearing precision, improve bearing stable rotation performance.The internal diameter of bearing inner race 2 is truncated cone-shaped.The axle
Hold design hole for hoist 5 on inner ring 2 and outer ring 1.The bearing outer ring 1 is split outer ring.Roller and bearing internal external circle are using senior
Just, retainer 3 uses high-quality copper product to bearing.Using Technology for Heating Processing, it is ensured that surface will not in heat treatment for bearing internal external circle
Crack, reduce Internal and external cycle deflection；Carry out repeatedly additional tempering, grinding, it is ensured that the precision of Internal and external cycle, is that one kind is applied to
The high-revolving Biserial cylindrical roller bearing of the frivolous series high accuracy of ultra-large type.
