Abstract

The utility model discloses a kind of oar blade type and stir base bearing, comprise support plate (4), half-and-half type bearing shell and stir spindle nose (3); Described support plate is provided with mounting hole; Described half-and-half type bearing shell comprises the first Semi round bottom bearing shell (1) and the second Semi round bottom bearing shell (2), and this first Semi round bottom bearing shell (1) and the second Semi round bottom bearing shell (2) are docking together and form complete watt of axle, and are arranged in described mounting hole; Gap is left between described mounting hole and half-and-half type bearing shell; Described stirring spindle nose (3) is inserted between described first Semi round bottom bearing shell (1) and the second Semi round bottom bearing shell (2), and described stirring spindle nose (3) and leave gap between described first Semi round bottom bearing shell (1) and the second Semi round bottom bearing shell (2); Height between the step of described stirring spindle nose (3) and support plate (4) is higher than the height of the first half base bearings (1) and the second half base bearings (2).Use the utility model can change bearing shell very easily.

Description

A kind of oar blade type stirs base bearing

Technical field

The utility model belongs to mechanical field, is specifically related to a kind of oar blade type and stirs base bearing.

Background technique

It is that the mode of fixed integral bottom bearing shell limits its spindle swing that existing oar blade type stirs what adopt, although adopt the stirring of this base bearing to operate steadily, operation period also can reach the requirement of general user, but spare parts consumption is but relatively many, and owing to stirring the impact of the factor such as the vertical centering of main shaft and base bearing installation deviation, often cause the serious eccentric wear of base bearing, even there is spindle nose, bearing shell, the situation that support plate all damages because of eccentric wear, cause a large amount of spare part changing eccentric wear between turn(a)round, not only damage spare part, also the repair time is extended, cause unnecessary manpower, material resources drop into.

Model utility content

The purpose of this utility model is for prior art Problems existing, provides a kind of oar blade type to stir base bearing.

Above-mentioned purpose is realized by following proposal:

A kind of oar blade type stirs base bearing, it is characterized in that, described bearing comprises support plate (4), half-and-half type bearing shell and stirs spindle nose (3); Described support plate is provided with mounting hole; Described half-and-half type bearing shell comprises the first Semi round bottom bearing shell (1) and the second Semi round bottom bearing shell (2), and this first Semi round bottom bearing shell (1) and the second Semi round bottom bearing shell (2) are docking together and form complete watt of axle, and are arranged in described mounting hole; Gap is left between described mounting hole and half-and-half type bearing shell; Described stirring spindle nose (3) is inserted between described first Semi round bottom bearing shell (1) and the second Semi round bottom bearing shell (2), and described stirring spindle nose (3) and leave gap between described first Semi round bottom bearing shell (1) and the second Semi round bottom bearing shell (2); Height between the step of described stirring spindle nose (3) and support plate (4) is higher than the height of the first half base bearings (1) and the second half base bearings (2).

The beneficial effects of the utility model:

1, from fixed installation mode become suspended movable install make bearing shell be subject to the frictional impact of main-shaft spindle head when stirring and rotating time in rotary moving in support plate mounting hole, thus avoid the eccentric wear of main-shaft spindle head and bearing shell.

2, half-and-half type bearing shell can solve the mode that bearing shell disassembly-type must will could be dismantled or install after the dismounting of one of main-shaft spindle head or support plate, and bearing shell is inserted between support plate mounting hole and main-shaft spindle head from main-shaft spindle head side.Thus solve the eccentric wear problem needing centering and lower shaft spare part after oar blade type stirs lower shaft maintenance.

3, owing to solving the eccentric wear problem of lower shaft spare part, the particularly eccentric wear problem of lower shaft watt, and change lower shaft watt into half-and-half type, carry out built-up welding just can reuse so only need when being stirred in maintenance from the side two half-and-half type bearing shells to be taken out respectively, and without the need to needing the dismounting mode of removing main-shaft spindle head 3 or support plate 4 as original paper, thus avoid stir engineering time long, spare parts consumption mainly with and the large problem of maintenance workload.

Fig. 3 is the plan view of half-and-half type bearing shell of the present utility model.

Embodiment

See Fig. 1-Fig. 3, oar blade type of the present utility model stirs base bearing and comprises support plate 4, half-and-half type bearing shell and stir spindle nose 3.Support plate 4 is provided with mounting hole 5; Half-and-half type bearing shell comprises the first Semi round bottom bearing shell 1 and the second Semi round bottom bearing shell 2, first Semi round bottom bearing shell 1 and the second Semi round bottom bearing shell 2 and is docking together and forms complete watt of axle, and is arranged in mounting hole 5, leaves gap between mounting hole 5 and half-and-half type bearing shell; Stir spindle nose 3 and insert (manhole namely inserting formation between the first Semi round bottom bearing shell 1 and the second Semi round bottom bearing shell 2 is interior) between the first Semi round bottom bearing shell 1 and the second Semi round bottom bearing shell 2, and stir spindle nose 3 and between the first Semi round bottom bearing shell 1 and the second Semi round bottom bearing shell 2, leave gap (leave appropriate gap, spindle nose can be rotated in bearing shell); Stir height between the step of spindle nose 3 and support plate 4 height (slightly exceeding to facilitate bearing shell conveniently to take out) higher than the first half lower shafts watt 1 and the second half lower shafts watts 2.
