Abstract

A greasing device for a vertical motor rolling bearing comprises a bearing seat (1) and a rolling bearing (2). An outer bearing cap (4) is provided with a greasing pipe (3), and a gap between the outer bearing cap (4) and a grease slinger (5) is reserved to be 1mm. According to the greasing device for the vertical motor rolling bearing, lubricating grease directly enters a bearing chamber through the greasing pipe arranged on the outer bearing cap, the gap between the outer bearing cap and the grease slinger is 1mm, and the lubricating grease can be prevented from entering an area between the grease slinger and the outer bearing cap, so that a friction area between the grease slinger and the lubricating grease is reduced while frictional heating is reduced. By the greasing device for the vertical motor rolling bearing, the bearing can be lubricated sufficiently, assembly inside of the bearing is kept clean and convenient in maintenance.

Description

A kind of vertical machine rolling bearing oiling device

Technical field

The utility model relates to a kind of motor component, relates in particular to a kind of vertical machine rolling bearing oiling device.

Background technique

In mechanical transmission, bearing is an important part, and the length of baering life limit directly affects the working life of entire machine, and the lubricated key that directly influences the baering life limit of bearing.Current most of rolling bearing vertical machine oiling mode is directly grease-added on bearing end cover; Because the excesssive gap between disc and the bearing end cover; The lubricating grease directly gap between bearing end cover and disc gets into outer cover cavity, and lubricating grease all gets lodged between disc and the enclosing cover, has both increased the area of contact of a upper rotative portion and lubricating grease; It is lubricated fully that bearing can not get, and causes bearing temperature too high.

The model utility content

The purpose of the utility model provides a kind of vertical machine rolling bearing oiling device, can solve bearing and can not get lubricated fully technical problem.

The purpose of the utility model realizes as follows: a kind of improved vertical machine rolling bearing oiling device, comprise bearing support, rolling bearing, and bearing end cover is provided with oil filling pipe, and the gap between bearing end cover and the disc is made as 1mm.

The structure that the utility model adopts; Lubricating grease directly gets into bearing chamber through the oil filling pipe on the bearing end cover, and the gap 1mm between bearing end cover and the disc prevents that lubricating grease from getting between disc and the bearing end cover; Both reduce the friction area of disc and lubricating grease, reduced frictional heating.Bearing has obtained lubricated fully, and bearing assembling inside has kept cleaning, makes easy to maintenance.

Description of drawings

For the content that makes the utility model is expressly understood more easily, below according to specific embodiment and combine accompanying drawing, the utility model is done further detailed explanation, wherein:

Shown in Figure 1 is the structural representation of the utility model.

Among the figure: 1, bearing support 2, rolling bearing 3, oil filling pipe 4, bearing end cover 5, disc

Embodiment:

With reference to accompanying drawing, a kind of vertical machine rolling bearing oiling device comprises bearing support 1, rolling bearing 2, and bearing end cover 4 is provided with oil filling pipe 3, and the gap between bearing end cover 4 and the disc 5 is made as 1mm.

Have oil filling pipe on the bearing end cover, lubricating grease directly gets into bearing chamber through oil filling pipe, gets between disc and the bearing end cover in order to prevent lubricating grease; Gap between bearing end cover and the disc is changed the little 1mm that is; So both reduced the friction area of disc and lubricating grease, and reduced frictional heating, bearing has obtained lubricated fully again; Bearing assembles inner open country and has kept cleaning, makes easy to maintenance.

Above-described specific embodiment; Purpose, technological scheme and beneficial effect to the utility model have carried out further explain, it should be understood that the above is merely the specific embodiment of the utility model; Be not limited to the utility model; All within the spirit and principle of the utility model, any modification of being made, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.

Claims

1. a vertical machine rolling bearing oiling device comprises bearing support, rolling bearing, and it is characterized in that: bearing end cover is provided with oil filling pipe, and the gap between bearing end cover and the disc is 1mm.
