Abstract

The utility model provides a thrust piece of low -speed diesel engine, is a fan -shaped component, sets up in the place ahead of the bent axle of low -speed diesel engine its characterized in that: thrust piece lower part orthodrome department is close to one side of bent axle is equipped with the abrupt lip that extends down earlier on, and suddenly the thickness of lip is lighter than the whole thickness of thrust piece and cross sectional shape are for trapezoidal. The utility model discloses an it is regional that suddenly the lip lies in the high capacity of thrust piece, has consequently increased the lifting surface area of thrust piece, has improved the situation that position atress in border was concentrated under the thrust piece effectively, has avoided the rising of load, has reduced the wearing and tearing of thrust piece, thereby lengthened the whole running cost that the life of thrust piece has reduced the diesel engine.

Description

A kind of thrust block pad of low-speed diesel engine

Technical field

This utility model relates to the structure of low-speed diesel engine component to be improved, be specifically related to a kind of can the thrust block pad of equally loaded low-speed diesel engine, belong to Diesel Engine Technique Field.

Background technology

During marine low speed diesel engine ahead operation, the axial thrust of propeller is delivered to thrust ring by tailing axle and jackshaft, refer to Fig. 1, thrust is passed to the support 4 of diesel engine by thrust ring by being positioned at the thrust block pad 2 in bent axle 1 front and thrust disc, support 4 passes to hull further through foundation bolt, thus promotes boats and ships to advance.The critical component of thrust is thrust block pad 2.

The thrust block pad 2 of conventional low-speed diesel engine is a fan-shaped block part, refer to Fig. 2, when the thrust of propeller drives hull, thrust causes a high load area at fan-shaped thrust block pad 2 orthodrome position on the lower, this high load area is susceptible to Fast Wearing, thus cause the damage of thrust block pad 2, reduce the life-span of thrust block pad 2, improve the operating cost of boats and ships.

Utility model content

The purpose of this utility model is, overcome the deficiencies in the prior art, the thrust block pad of a kind of novel low-speed diesel engine is provided, improve original thrust block pad, thrust block pad increases an extra lip type structure, effectively improve the situation that position, thrust block pad lower edge stress is concentrated, it is to avoid the rising of load, extend the service life of thrust block pad.

The technical scheme in the invention for solving the technical problem is as follows:

The thrust block pad of a kind of low-speed diesel engine, is a fan-shaped component, is arranged at the front of the bent axle of low-speed diesel engine, it is characterised in that: the side of the close described bent axle at the orthodrome of described thrust block pad bottom is provided with a prominent lip extended downwards.

Further, the thickness of described prominent lip is less than the integral thickness of described thrust block pad.

Further, the cross sectional shape of described prominent lip is inverted trapezoidal.

Compared with the structure of existing thrust block pad, this utility model achieves following technique effect:

The described prominent lip setting up the close bent axle side at the orthodrome of bottom is positioned at the high load area of thrust block pad, therefore the lifting surface area of thrust block pad is added, effectively improve the situation that position, thrust block pad lower edge stress is concentrated, avoid the rising of load, decrease the abrasion of thrust block pad, extend the service life of thrust block pad thus decrease the overall operation cost of diesel engine.

Accompanying drawing explanation

Fig. 1 is the stress sketch of existing thrust block pad.

Fig. 2 is the structure diagram of existing thrust block pad.

Fig. 3 is structure diagram of the present utility model.

Fig. 4 is the force-bearing situation sketch after this utility model is installed.

Detailed description of the invention

With specific embodiment, the thrust block pad of low-speed diesel engine described in the utility model is described in further detail below in conjunction with the accompanying drawings, but protection domain of the present utility model should not limited with this.

Refer to Fig. 4, it is illustrated that the thrust block pad 2 of low-speed diesel engine is arranged at the front of the bent axle 1 of low-speed diesel engine, and is fixed on the support 4 of diesel engine.

Referring to Fig. 3, described thrust block pad 2 is a fan-shaped component, and top is small arc-shaped, and bottom is orthodrome.At the orthodrome of described thrust block pad 2 bottom and near the side of described bent axle 1, being provided with a prominent lip 3 extended downwards, the thickness of this prominent lip 3 is less than the integral thickness of described thrust block pad 2, and cross sectional shape is inverted trapezoidal (see Fig. 4).

State of installing and using of the present utility model is shown in Fig. 4, the prominent lip 3 extended downwards is positioned at the high load area of thrust block pad 2, therefore the lifting surface area of thrust block pad 2 is added, effectively improve the situation that position, thrust block pad 2 lower edge stress is concentrated, avoid the rising of load, decrease the abrasion of thrust block pad 2, extend the service life of thrust block pad 2, thus decrease the overall operation cost of diesel engine.
