Description
Technical field
This utility model relates to a kind of transport rolling member, particularly relates to a kind of dust-proof roller excessively.
Background technology
Typically it is made up of parts such as roll shaft 1 ', roller 2 ', bearing 3 ' and end caps 4 ' as it is shown in figure 1, cross roller.Transport, the effect rolling and supporting can be played owing to crossing roller, it is frequently seen in the industrial production so crossing roller, roller all it was be unable to do without in producing such as the leaflet of food packing machine, medicine packaging machinery and the overwhelming majority, especially being widely used especially in lithium ion battery produces, the lithium ion battery such as such as coating machine, banding machine, electrode sheet forming machine, up-coiler, laminating machine and packer produces equipment and the most all be unable to do without roller.But existing cross roller typically use end cap 4 ' directly to expose the mounting means such as (see figure 2) with the concordant (see figure 1) in roller 2 ' end or bearing 3 ', cause existing mistake roller generally there is bearing catching phenomenon.And the main cause of bearing clamping stagnation is that bearing seal effect is poor, the minute dusts that so supplied materials produces in transportation easily enters Bearing inner, and stick together with bearing ball or ball grooves, ball resistance in rotation process is made to significantly increase, and when dust accumulation may result in bearing wear and clamping stagnation to a certain extent.Additionally, prior art mainly has for crossing the delayed maintenance mode of roller card: 1) frequent cleans crosses roller surface dust；2) when bearing clamping stagnation is serious, bearing is changed.As can be seen here, prior art is crossed roller card delayed it is generally required to frequently change bearing, and maintenance cost is the highest, the most also substantially reduces the service life of roller.
In view of this, necessary existing roller of crossing is improved further, to solve existing to cross the bearing clamping stagnation problem that causes due to dust of roller.
Utility model content
The purpose of this utility model is: for the deficiencies in the prior art, and a kind of roller of crossing with dust reduction capability is provided, this dust-proof Bearing inner that roller can effectively prevent external dust from entering roller excessively, effectively solved roller bearing clamping stagnation problem, reduced scrappage and the later maintenance cost of roller.
To achieve these goals, this utility model employing solution below:
