Abstract

The utility model provides a subtract heavy propeller strut, includes support arm and bearing, the support arm is the T font, with bearing fixed connection, and its characterized in that: be provided with the lightening hole on the support arm, the support arm scribbles the rubber layer outward, be provided with the sealing washer on the bearing, the lightening hole increases to the tail end from the support arm top in proper order, the sealing washer is become by rubber, and the centre is provided with the filter screen, prevents that silt from getting into in the bearing. The utility model has the advantage of scientific and reasonable design, the setting of lightening hole has alleviateed the weight of support arm, and the setting on rubber layer can make the support arm avoid corroding, has the cushioning effect simultaneously, and the effect of sealing washer can prevent that silt from entering into bearing, extension propeller strut's life.

Description

A kind of loss of weight propeler bracket

Technical field:

The utility model relates to ship steel foundry goods apparatus field, specifically a kind of loss of weight propeler bracket.

Background technology:

Propeler bracket is positioned at the front of screw propeller, is that supporting ship advances shaft support outward, is made up of propeller boss and support arm.The tail bearing of boats and ships, to screw shaft of ship normal operation, for boats and ships provide effectively power, guarantees that boats and ships are normally operated and protect water environment to play vital effect.Therefore, select appropriate tail bearing to raising marine rear shaft running efficiency and marine propuision system normalisation significant.Crankshaft holder has single armed and both arms two kinds of forms usually.Two-arm yoke is generally applicable to big-and-middle-sized boats and ships, and small boat many employings single armed tail bearing, but single armed tail bearing Heavy Weight, be easily corroded, and running ship has impact.

Utility model content:

Technical problem to be solved in the utility model is the defect overcoming prior art, provides a kind of working weight lighter, more durable loss of weight propeler bracket.

Technical problem to be solved in the utility model adopts following technical scheme to realize:

A kind of loss of weight propeler bracket, comprise support arm and bearing, described support arm is in T shape, is fixedly connected with bearing, it is characterized in that: described support arm is provided with lightening hole, scribbles rubber layer outside described support arm, and described bearing is provided with seal ring.

Described lightening hole increases from support arm top successively to tail end.

Described seal ring is made up of rubber, and centre is provided with filtering net, prevents silt from entering in bearing.

The utility model design science is reasonable, and the setting of lightening hole alleviates the weight of support arm, and the setting of rubber layer can make support arm avoid corrosion, and have buffer action, the effect of seal ring can prevent silt from entering into bearing simultaneously, extends the service life of propeler bracket.

Accompanying drawing illustrates:

Fig. 1 is structural representation of the present utility model;

Fig. 2 is seal ring schematic cross-section.

Detailed description of the invention:

The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.

As shown in Figure 1 and Figure 2, a kind of loss of weight propeler bracket, comprise support arm 1 and bearing 2, described support arm 1 is in T shape, be fixedly connected with bearing 2, described support arm 1 is provided with lightening hole 3, outside described support arm 1, scribbles rubber layer 4, described bearing 2 is provided with seal ring 5, described lightening hole 3 increases from support arm 1 top successively to tail end, described seal ring 5 is made up of rubber, and centre is provided with filtering net 6, prevents silt from entering in bearing 2.

More than show and describe groundwork of the present utility model and principal character and advantage of the present utility model.The technical personnel of the industry should be understood; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification sheets just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
