In the surface propeller propelling device, a rudder device is not arranged, and the lateral force is generated by changing the included angle between the propeller propelling force and the movement direction of a ship body, so that the course of the ship is controlled. The steering of the shafting can be realized by a universal coupling, and the steering function of the shafting supporting component is realized by a ball joint. After the universal coupling is arranged, a shafting can only transmit torque, axial force cannot be transmitted, and thrust or pull force generated by the propeller is also transmitted to the ship body through the ball joint. The ball joint generally comprises a ball seat, a ball body, a sealing element, a lubricating oil groove and the like. Wherein, the ball seat is the cylinder, and inside is provided with ball bush, and ball bush is embedded in the ball seat, and ball village cover one end medial surface is the sphere, and this sphere cooperatees with the spheroid, and spheroid one end is cylinder and the hollow spheroid two of the other end combine, and the spheroid is connected through solid fixed ring and sealing member with ball seat and ball bush. The traditional ball seat and ball village sleeve are integrated, the ball body is solid, and the following problems exist in the form: 1. there are major difficulties in oil groove placement and processing. 2. The upper portion oil groove position is lower, and the lubricating oil of the highest position in the ball seat can't be through the circulation of gravity oil tank, and the temperature risees, and easily causes upper portion ball joint department lubricated not in place to increase the wearing and tearing risk. 3. The sphere is a solid sphere and is heavy.

Disclosure of Invention

An object of the utility model is to above-mentioned technical demand and provide a ball type universal support joint, along with the shafting swing and swing, have good sealed, protection, lubrication and support function to the shafting universal joint, can adapt to outboard operational environment, have good resistant seawater corrosion and operational reliability.

In order to achieve the above purpose, the utility model adopts the following technical scheme: the utility model provides a universal support joint of ball type which characterized in that: including ball seat, bush, solid fixed ring and spheroid, the ball seat is the cylinder sleeve structure, and the afterbody outer peripheral face is equipped with first flange along circumference, gu fixed ring outer peripheral face is equipped with second flange, ball seat head terminal surface with second flange passes through bolted connection, the bush is cylinder tube structure, outer peripheral face and ball seat inner peripheral surface interference fit link to each other with the ball seat through the bolt, and bush inner wall front end and solid fixed ring inner wall are the arc surface, and the bush forms the convex profile face of following the cunning with solid fixed ring's internal face combination, spheroidal bulb profile face with convex profile face disposes mutually, and the bulb slides along convex profile face.

According to the scheme, the outer peripheral surface of the bushing is symmetrically provided with the upper oil groove and the lower oil groove along the axial direction, the first connecting flange is symmetrically provided with the upper oil port and the lower oil port, and the upper oil groove and the lower oil groove are communicated with the upper oil port and the lower oil port.

According to the scheme, the first sealing groove is formed in the head end of the ball seat, and the first sealing ring is arranged in the first sealing groove.

According to the scheme, the inner wall of the fixing ring is provided with a plurality of second sealing grooves which are provided with second sealing rings.

According to the scheme, the ball body is of a hollow structure.

The utility model has the advantages that: the spherical universal support joint is provided, the oil groove is convenient to process, and the vertical synchronous lubrication is more sufficient; the ball seat and the lining are designed separately, so that the easy disassembly and assembly are fully considered, and the maintenance and the replacement are convenient; the designed sphere is a hollow sphere, so that the weight is maximally reduced; the joint of the fixing ring, the ball seat and the ball body is provided with the sealing ring, so that the waterproof and dustproof operation is effectively realized.

Drawings

Fig. 1 is a schematic structural diagram of an embodiment of the present invention.

Wherein: ball seat 1, bush 2, solid fixed ring 3, spheroid 4, first flange 5, second flange 6, go up oil groove 7, lower oil groove 8, go up oil mouth 9, lower hydraulic fluid port 10, first sealing washer 11, second sealing washer 12.

Detailed Description

The embodiments of the present invention will now be described with reference to the accompanying drawings, but the present invention is not limited to the following embodiments.

As shown in figure 1, a ball type universal support joint is characterized in that: including ball seat 1, bush 2, solid fixed ring 3 and spheroid 4, the ball seat is the cylinder sleeve structure, the afterbody outer peripheral face is equipped with first flange 5 along circumference, install on the tail shrouding of ship through the bolt, gu fixed ring outer peripheral face is equipped with second flange 6, ball seat head terminal surface passes through bolted connection with second flange, the bush is cylinder tube structure, outer peripheral face and ball seat inner peripheral surface interference fit, link to each other with the ball seat through the bolt, bush inner wall front end and solid fixed ring inner wall are the arc surface, the bush forms the convex profile face of following the smoothness with solid fixed ring's internal face combination, spheroidal bulb profile face disposes with convex profile face mutually, the bulb slides along convex profile face.

The outer peripheral surface of the bushing is symmetrically provided with an upper oil groove 7 and a lower oil groove 8 along the axial direction, the first connecting flange is symmetrically provided with an upper oil port 9 and a lower oil port 10, the upper oil groove and the lower oil groove are communicated with the upper oil port and the lower oil port, the connection between the upper oil port and the lower oil port is convenient, the connection between the inlet circulation oil pipe and the outlet circulation oil pipe of the gravity oil tank is facilitated, and the lubrication and.
