Description
Technical field
The present invention relates to a kind of roller that is used for spinning machine drafting systems (top roller) with feature of claim 1 preamble.
Background technology
In spinning machine drafting systems, use roller to carry out drawing of fiber as donor rollers, conveying roller and belt leather roller.
DE-AS 1 164 288 has described a kind of roller that is used for spinning machine drafting systems, and wherein two roll bodies are installed on the shared axle (arbor) rotationally.On the inboard, with respect to environmental sealing, the sealing part has two sealing flanges that are spaced apart from each other and arrange but roll body passes through the seal of axially-movable.Between these two sealing flanges and outer collar bearing, there is seal clearance.Under the situation of this class sealing, dirt particle, particularly fiber grain can penetrate into by seal clearance.Therefore, roller is configured to and can easily cleans reliably inside, the dirt that penetrates into removing.
Similar DE 195 09 055 C1 show the two rollers that are used for spinning machine drafting systems, and this pair roller comprises respectively by two rolling bearings and is installed in roll body on the shared continuous axle end.The roll body that is called outer shroud of top roll crosses out on the axle end.They are provided with covering members in the end, and this covering members forms at least a portion of the cylindrical cover (jacket) of roller.
The cycle of lubrication time again of the roller of current installation ball has been compared sizable increase with design early.Traditionally, after being about 50,000 hours running time, roller is carried out lubricating again, particularly all the more so when roller is used as donor rollers or conveying roller.Compare donor rollers or conveying roller or with the band roller with high relatively load operation or with high relatively speed operation.Regardless of their field of employment, the roller of drafting system generally all has identical project organization.Therefore, can be the roller of known design as the band roller provides and is enough to be used in lubricated throughout one's life lubricating oil.On the other hand, under the situation of the roller that is used as donor rollers or conveying roller, same lubricating oil just is not enough to as lubricated throughout one's life.Be well known that, be configured to make it to have lubrication hole again the closing cap of roller.Because this is lubrication hole and can carry out again lubricated in simple mode by means of suitable lubricating structure more again.In order to make lubrication time keep longly as far as possible at interval, expectation is the sealed bearing device well again.This can not undertaken by there being the friction clearance seal as known from DE-AS 1 164 288 or DE 195 09 055 C1, or alternatively, is undertaken by self-regulation many washer sealings that rub.Yet,, just must accept quite high expense for the effect of better seal a little of many washer sealings.When lubricating again, all there is the danger of safeguarding maloperation under the gap sealed situation and under the situation of the many washer sealings of friction.This maloperation may comprise that lubricant is under-supply and to the over-lubrication of mounting structure (mounting).Under the situation of over-lubrication, lubricant overflows by seal clearance owing to excessive filling.Lubricant overflows and may directly occur in during the greasing itself again, perhaps occurs in the bearing run duration owing to the abrasive action by grease increases bearing friction.The lubricant grease that has overflowed is collected considerable dirt and fiber.If carefully do not clean roller before lubricated again, then dirt may be brought in the bearing arrangement owing to greasing again.The operating condition of roller has very high requirement to lubricant.In order to realize gratifying running time, must adopt expensive special fat.Except above-mentioned defective, the increase that mistake or unsuitable maintenance all will cause lubricant to consume, thus cause maintenance cost unnecessarily to increase.
