Abstract
A shock absorption sleeve of direct bearing type rotor pertains to the manufacturing technology field of spinning equipment, and consists essentially of a direct bearing type rotor and a shock absorption sleeve. The direct bearing type rotor is composed of a core shaft (1) with a rotor (16) and a steel ball (2), a bearing outer ring (11) with a bearing oil drain hole (12) which is positioned on the core shaft (1). The shock absorption sleeve (6) is composed of an inner casing (3), an outer casing (13) with an outer casing oil drain hole (5), and a shock absorption ring (6) with an inner ring (9) and an outer ring (10) that is positioned between the inner casing (3) and the outer casing (13). The inner casing (3) and the bearing outer ring (11), the inner casing (3) and the outer casing (13) are in fixed connection respectively by a clamping bolt (4). The utility model has a reasonably designed structure, low manufacturing cost, can effectively absorb the vibration caused by the operation of the rotor during working, reduce collision dynamics, buffer effect, prolong the service life of the rotor bearing, reduce vibration, noise and power and make the operation of the whole machine more stable.
Description
Technical field
The utility model relates to a kind of direct bearing-type revolving cup shock-absorbing sleeve, belongs to the manufacturing technology field of spinning equipment.
Background technology
Existing rotor spinning machine (open-end spinning frame) does not reach theoretic absolute equilibrium with direct bearing-type revolving cup sub-assembly owing to dynamic balancing, add that also there is certain play in direct bearing, play also will increase after the long-term operation, running up down, because will produce vibrations under the action of centrifugal force, noise increases, and power consumption also increases thereupon, thereby shortens the service life of bearing and the stability of complete machine.
Summary of the invention
The purpose of this utility model provides a kind of reasonable in design, can effectively absorb the vibrations that the revolving cup running is produced when revolving cup turns round, the direct bearing-type revolving cup shock-absorbing sleeve of good damping effect.
The utility model is direct bearing-type revolving cup shock-absorbing sleeve, comprise mandrel by band revolving cup and steel ball, place the direct bearing-type revolving cup of the formations such as bearing outer ring outside the mandrel, it is waited to levy and is that bearing outer ring also is provided with by interior cover and overcoat outward, is with the shock-absorbing sleeve of the formations such as shock absorbing ring of inner ring and outer ring in placing between cover and the overcoat.
Available holding screw is fixedly connected between described interior cover and the bearing outer ring.Available overcoat holding screw is fixedly connected between described interior cover and the overcoat.Described outer putting also can be provided with the overcoat tank filler sleeve.
Also can be provided with the bearing tank filler sleeve on the described bearing outer ring.
The utility model reasonable in design, low cost of manufacture, easy to maintenance, the vibrations that produced in the time of effectively absorbing the revolving cup operation during work reduce the collision dynamics, cushioning effect, prolong the service life of rotor bearing, reduce vibrations, noise, power consumption, make the complete machine operation more stable.
Description of drawings
Accompanying drawing is an overall structure schematic diagram of the present utility model.
Among the figure: 1 is mandrel, and 2 is steel ball, and 3 is interior cover, 4 is holding screw, and 5 is the overcoat tank filler sleeve, and 6 is shock absorbing ring, 7 is the overcoat holding screw, and 8 is tengential belt, and 9 is inner ring, 10 is the outer ring, and 11 is bearing outer ring, and 12 is the bearing tank filler sleeve, 13 is overcoat, 14 is direct bearing-type revolving cup, and 15 is shock-absorbing sleeve, and 16 is revolving cup.
The specific embodiment
The utility model mainly comprises direct bearing-type revolving cup 14 and shock-absorbing sleeve 15, directly bearing-type revolving cup 14 by the mandrel 1 of band revolving cup 16 and steel ball 2, place mandrel 1 in addition the bearing outer ring 11 etc. of bearing tank filler sleeve 12 constitute, shock-absorbing sleeve 15 is with the formations such as shock absorbing ring 6 of inner ring 9 and outer ring 10 by the overcoat 13 of interior cover 3 and band overcoat tank filler sleeve 5 between cover 3 and the overcoat 13 in placing.Fixedly connected between interior cover 3 and the bearing outer ring 11 with holding screw 4, fixedly connected between interior cover 3 and the overcoat 13 with overcoat holding screw 7.
Directly bearing-type revolving cup 14 is by tengential belt 8 rotations, revolving cup 16 when running up because there is certain play when installing in mandrel 1, steel ball 2, bearing outer ring 11, add and also exist dynamic equilibrium problems after mandrel 1 and revolving cup 16 install, under the centrifugal action when running up, mandrel 1, steel ball 2, bearing outer ring 11 can bump, produce certain vibrations, overlap 3 in vibrations are directly passed to, pass to inner ring 9 by interior cover 3 again, pass on the shock absorbing ring 6 by inner ring 9 again, by passing on the outer ring 10 after shock absorbing ring 6 dampings, pass to overcoat 13 at last.
Claims (5)
1, a kind of direct bearing-type revolving cup shock-absorbing sleeve, comprise mandrel (1) by band revolving cup (16) and steel ball (2), the direct bearing-type revolving cup (14) that places the outer bearing outer ring (11) of mandrel (1) to constitute, it is waited to levy and is that bearing outer ring (11) is outer and also is provided with by interior cover (3) and overcoat (13), places between interior cover (3) and the overcoat (13) shock-absorbing sleeve (15) with shock absorbing ring (6) formation of inner ring (9) and outer ring (10).
2,, it is characterized in that between described interior cover (3) and the bearing outer ring (11) fixedly connected with holding screw (4) by the described direct bearing-type revolving cup shock-absorbing sleeve of claim 1.
