Abstract
The invention relates to a spherical bearing vertical type crown gear coupling which is provided with an upper gear sleeve, a middle gear shaft and a lower gear sleeve. The upper gear sleeve is connected with the lower gear sleeve through the middle gear shaft, a spherical bearing is arranged between the middle gear shaft and the upper gear sleeve, and the upper gear sleeve is in spherical contact with the spherical bearing; or a spherical bearing is arranged between the middle gear shaft and the lower gear sleeve, and the middle gear shaft is in spherical contact with the spherical bearing. Oil leakage holes used for leaking oil for lubrication are formed in the engagement portion of the middle gear shaft and the upper gear sleeve, the engagement portion of the middle gear shaft and the lower gear sleeve and the spherical contact portions. According to the spherical bearing vertical type crown gear coupling, the spherical bearing is combined with the design of the vertical type coupling, certain angular displacement and a certain radial displacement deviation which exist in the shafting center are allowed, and the compensatory capacity and the bearing capacity of the vertical type coupling are improved. Meanwhile, the coupling and a supporting spherical surface rely on the oil leakage holes for the lubrication, the working conditions are greatly improved, and the vertical installation of the crown gear coupling is further improved.
Description
Technical field
The present invention relates to a kind of at right angle setting coupling, especially a kind of crown gear coupling.
Background technique
Crown gear coupling is widely used in the connection of the horizontal drive shaft run up.For the connection of vertical drive shaft, the vertically arranged coupling of current domestic existing and external introduction, because structure lacking effective supporting, its compensation ability and bearing capacity receive larger restriction.Russia once designed vertical supporting coupling, but from relevant material object, supporting surface is by axle center, and in the process that runs up, coupling and supporting surface lack lubrication, and operating conditions is comparatively severe.
There is subject matter in existing crown gear coupling:
1) if crown gear coupling directly applies to vertical installation, the rigid plane of its end cap and axle head supports, two axial lines deflection not active, angular displacement and radial displacement compensation ability limited.
2) axle system runs up and makes coupling end cap and axle head produce larger sliding friction, affects the working life of tooth cover, and unit operation may be caused unstable.
Be difficult to be applied to vertical installation for existing crown gear coupling, rigid plane supports and causes compensation ability limited, and operating conditions worsens, and causes the problem that unit running is unstable, needs a kind of spherical bearing crown gear coupling connected for vertical drive shaft.At present both at home and abroad without the vertical crown gear coupler device of spherical bearing.
Summary of the invention
Problem to be solved by this invention is: be directed to crown gear coupling and be difficult to be applied to vertical installation, rigid plane supports and causes compensation ability limited, operating conditions worsens, cause the problem that unit running is unstable, and a kind of spherical bearing vertical crown gear coupler connected for vertical drive shaft is provided.
For achieving the above object, technological scheme of the present invention is:
A kind of spherical bearing vertical crown gear coupler, there is a upper tooth cover, intermediate gear shaft, a lower tooth cover, be connected by intermediate gear shaft between upper tooth cover overlaps with lower tooth, between described intermediate gear shaft and upper tooth overlap, be provided with spherical bearing, sphere-contact between upper tooth cover and spherical bearing; Or be provided with spherical bearing between intermediate gear shaft and lower tooth overlap, sphere-contact between intermediate gear shaft and spherical bearing.
Intermediate gear shaft and upper tooth overlap engagement place, intermediate gear shaft and lower tooth and overlap engagement place and sphere-contact place and be equipped with the oil leaking hole lubricated for leakage of oil.
Spherical bearing vertical crown gear coupler is outer gearing coupling, intermediate gear shaft is provided with external tooth gear, upper tooth cover is connected by gears meshing with intermediate gear shaft, upper tooth cover is by Upper shaft sleeve connection for transmission axle, lower tooth cover 4 is connected by gears meshing with intermediate gear shaft 3, lower tooth cover is by Lower shaft sleeve connection for transmission axle, and upper and lower axle sleeve is provided with oil leaking hole.
Spherical bearing vertical crown gear coupler is internal messing coupling, and intermediate gear shaft is provided with internal-gear, and intermediate gear shaft is fixedly connected with spherical bearing, and is connected with a joggle by internal-gear with upper tooth cover, lower tooth cover, and upper tooth is arranged with oil leaking hole.
The invention has the beneficial effects as follows:
Spheric seating supporting is incorporated vertical coupling design by spherical bearing vertical crown gear coupler of the present invention, allows axial center to there is certain angular displacement and radial displacement deviation, improves compensation ability and the bearing capacity of vertical coupling.Simultaneously coupling with support sphere and rely on oil leaking hole to lubricate, operating conditions is greatly improved, the perfect further at right angle setting of crown gear coupling.
The present invention compares existing gear coupling and has the following advantages:
1, the compensation ability of vertical type transmission coupling is improved;
2, the bearing capacity of coupling is improved;
3, the lubrication effect of supporting surface and jack shaft end face is increased.
