Abstract
The utility model relates to a bearing assembling and disassembling tool which comprises a hydraulic cylinder, a body, a connecting piece and a connecting bolt, wherein the body is of a tubular structure with one closed end, the inner diameter of the body is 1-12mm larger than the inner diameter of an inner ring of a bearing, the outer diameter of the body is 0-3mm smaller than the outer diameter of the inner ring of the bearing, the closed end of the body is connected with the hydraulic cylinder, and the connecting piece is connected with the body through the connecting bolt. The bearing assembling and disassembling tool has the advantages that the bearing is assembled or disassembled by using the pushing force or the tension force of a piston rod of the hydraulic cylinder, the bearing is stressed uniformly, is hardly damaged and deformed; the tool is simple in structure, can be used assembling and disassembling the bearing conveniently in a time-saving and labor-saving manner, and is capable of prolonging the service life of the bearing and reducing the labor intensity.
Description
Technical field
The utility model relates to a kind of bearing handling instrument.
Background technology
Bearing is widely used in machinery industry, assembling for bearing, when especially part and part closely cooperate assembling, owing to there is not suitable bearing installing tool, usually directly knock with hammer and fix or fix by knocking the power transmission rod, cause in assembling process firmly different because making, stress point is also different, often make top and bottom behind the Assembly of the parts, about the face discontinuity, be not steadily to enter but crookedly enter when bearing is mounted into, the extent of damage to bearing is higher, and the damage ratio that particularly bearing inner race is caused is larger, and mechanical service life and the degree of reliability of using this bearing are brought adverse effect.
Summary of the invention
For overcoming the deficiencies in the prior art, the purpose of this utility model provides a kind of bearing handling instrument, makes shaft strength even, utilizes hydraulic cylinder to be power resources, makes bearing injury-free.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of bearing handling instrument comprises hydraulic cylinder, body, connector, connecting bolt, and body is the tubular structure of end sealing, internal diameter is greater than bearing inner race 1-12mm, external diameter is less than bearing inner race external diameter 0-3mm, and the body blind end is connected with hydraulic cylinder, and connector is connected by connecting bolt with body;
The described body other end also is provided with outer ring body, and outer ring body and body are structure as a whole, and the outer ring body external diameter is greater than bearing outer ring external diameter 1-20mm, and the outer ring body internal diameter is greater than bearing outer ring internal diameter 0-2mm.
Compared with prior art, the beneficial effects of the utility model are:
The primer fluid cylinder pressure utilizes the thrust of piston rod, and bearing is installed or unloaded, and shaft strength is even, easy damaged distortion, and simple in structure, assembling bearing is convenient, and is time saving and energy saving, improves bearing service life, reduces labour intensity.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is structural representation of the present utility model (band outer ring body).
Among the figure: 1-hydraulic cylinder 2-body 3-connecting bolt 4-bearing 5-connector 6-axle 7-outer ring body.
The specific embodiment
Below in conjunction with Figure of description the utility model is described in detail, but should be noted that enforcement of the present utility model is not limited to following embodiment.
See Fig. 1, Fig. 2, a kind of bearing handling instrument, comprise hydraulic cylinder 1, body 2, connector 5, connecting bolt 3, body 2 is the tubular structure of end sealing, internal diameter is greater than bearing 4 inner ring 1-12mm, external diameter is less than bearing 4 inner ring external diameter 0-3mm, and body 2 blind ends are connected with hydraulic cylinder 1, and connector 5 is connected by connecting bolt 3 with body 2;
Described body 2 other ends also are provided with outer ring body 7, and outer ring body 7 is structure as a whole with body 2, and outer ring body 7 external diameters are greater than bearing 4 outer ring external diameter 1-20mm, and outer ring body 7 internal diameters are greater than bearing 4 outer ring internal diameter 0-2mm.
During use, when tool body 2 contacted with bearing 4 inner rings, outer ring body 7 contacted with bearing 4 outer rings, utilize hydraulic cylinder 1 to be power resources, act on body 2 blind ends by piston rod, make bearing 4 stressed even, bearing 4 is injury-free, during bearing 4 dismounting, connector 5 is installed on body 2 or the outer ring body 7, this moment connector 5 contact bearings, hydraulic cylinder 1 pulling body, piston rod drives connector 5, and bearing 4 is unloaded from axle 6.
The utility model utilizes thrust or the pulling force of hydraulic cylinder piston rod, and bearing is installed or unloaded, and shaft strength is even, easy damaged distortion, and simple in structure, assembling bearing is convenient, and is time saving and energy saving, improves bearing service life, reduces labour intensity.
