Abstract
The invention discloses a turntable bearing of a marine crane, relating to the technical field of bearing manufacturing. The turntable bearing comprises an outer gear ring, an upper inner ring and a lower inner ring, wherein the upper inner ring and the lower inner ring are arranged in the outer gear ring, a sealing ring is arranged between the side wall of the upper inner ring and the upper end surface of the outer gear ring, the sealing ring is provided with a ring-shaped body arranged on the side wall of the upper inner ring, and an outer lip and an inner lip, which are arranged at the lower part of the ring-shaped body, the outer lip is connected with the inner side wall of a sealing ring groove of the outer gear ring in a pressing manner, and the inner lip is connected with the upper end surface of the outer gear ring in a pressing manner. Compared with the prior art, the turntable bearing of the marine crane can solve the problems that the existing turntable bearing can be eroded easily by seawater and cannot be maintained conveniently.
Description
Technical field
The present invention relates to bearing mnanufacture technical field, especially a kind of turntable bearing for loop wheel machine peculiar to vessel.
Background technique
Rotating tower body is one of vitals of loop wheel machine peculiar to vessel, and rotate tower body and be normally contained in bottom crane tower body by the turntable bearing being provided with external toothing, the external toothing of turntable bearing is connected with the driving gear being connected power engine by the gear teeth.Because the effect of loop wheel machine turntable bearing peculiar to vessel is used to supporting ship loop wheel machine and transmitting torque, so need to bear larger tilting moment and thrust load, there is steel ball to be difficult to meet marine severe operating mode in the raceway of existing turntable bearing, be vulnerable to the erosion of seawater, cause bearing premature failure; In addition, because turntable bearing size is large, the operation of turntable bearing is out of order not only dismounting inconvenience, also can cause maintenance difficult.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of loop wheel machine turntable bearing peculiar to vessel, is vulnerable to the erosion of seawater and the problem of inconvenient maintenance to solve existing turntable bearing.
The technological scheme that technical solution problem of the present invention adopts is: this loop wheel machine turntable bearing peculiar to vessel comprises external toothing and is located at the upper inner ring in described external toothing, lower inner ring, on described, be provided with seal ring between inner ring sidewall and described external toothing upper-end surface.
In above-mentioned loop wheel machine turntable bearing technological scheme peculiar to vessel, technological scheme can also be more specifically: described external toothing, described upper inner ring and lower inner ring, by multiple end to end ring section composition, are equipped with the overlap joint platform overlapped mutually between adjacent two sections.
Further: to be provided with closure gasket groove in described external toothing upper-end surface; Described seal ring have be located on described upper inner ring sidewall for ring body and be located at outer lip and the inner lip of this body lower part, described outer lip crimps mutually with the madial wall of described external toothing closure gasket groove, and described inner lip crimps mutually with described external toothing upper-end surface.
Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect: 1, owing to being provided with seal ring between upper inner ring sidewall and external toothing upper-end surface, seal ring serves the radial and axial effect simultaneously sealed, and effectively prevents the erosion of seawater; 2, the external toothing of turntable bearing, described upper inner ring and lower inner ring are by multiple end to end ring section composition easy accessibility, easy to maintenance.
