Abstract
The utility model relates to a bearing and use filament cutter feed agencies positioning device of this bearing, this contracting draw together the sleeve of being made by the polytetrafluoroethylene material, and telescopic medial surface is the normal running fit face, has seted up the terminal surface oil groove, has seted up the inside tank on the telescopic inner wall for one in the face of telescopic both ends. The utility model provides a bearing has wear -resistingly, the antiacid characteristic of alkali, can not produce the dead phenomenon of bearing corrosion card, can guarantee rotational stabilization nature, and simultaneously, the terminal surface oil groove has been seted up on the telescopic terminal surface, guarantee the lubricated effect of sleeve terminal surface, the inside tank has been seted up on the telescopic inner wall, when sleeve and pivot normal running fit, not only can reach the lubricated mesh between sleeve and the axle, furthermore, the inside tank still has appearance dirt, the function of holding bits, when having the dust in the sleeve, including the dust can be assembled in the oil groove, guarantee the stable cooperation between pivot and the sleeve.
Description
Technical field
The utility model relates to a kind of bearing and uses the cutting machine delivering gear positioning device of this bearing, belongs to throwing equipment technical field.
Background technique
Cutting machine is main process equipment important in tobacco cutting production line, and its main task is that treated tobacco leaf, offal are cut into the cut tobacco, the stem that meet technology for making tobacco threds and require.
Cutting machine has feed screw positioning device, bearing unit is provided with in feed screw positioning device, in prior art, bearing unit in feed screw positioning device is combined by plane bearing and needle bearing, because the installation control of bearing unit is narrow and small, in repair and maintenance process, dismounting and change bearing unit more complicated, expends time in longer; In addition, the environment at throwing scene is more severe, dust and moisture contamination are comparatively serious, bearing unit is easily caused to pollute, particularly clean rotor with water in everyday devices servicing operations, cause sewage to enter feed screw positioning device along gap inner, easily cause plane bearing and needle bearing corrosion stuck, rate of fault is higher, increases maintenance expenses.
Summary of the invention
The purpose of this utility model is to provide a kind of cutting machine delivering gear positioning device bearing, in order to solve the higher technical problem causing maintenance expenses high of bearing fault rate in prior art in cutting machine delivering gear positioning device.The purpose of this utility model is also to provide a kind of cutting machine delivering gear positioning device using this bearing.
For achieving the above object, the utility model adopts following technological scheme:
A kind of bearing, it is characterized in that: comprise the sleeve be made up of polytetrafluoroethylmaterial material, the inner side surface of sleeve is the face of being rotatably assorted, and one in the both ends of the surface of sleeve offers end face oil groove, the inwall of sleeve offers inside tank.
Positioning step is provided with outside described sleeve.
A kind of cutting machine delivering gear positioning device, comprise bearing, it is characterized in that: described bearing comprises the sleeve be made up of polytetrafluoroethylmaterial material, one in the both ends of the surface of sleeve offers end face oil groove, the inwall of sleeve offers inside tank.
Positioning step is provided with outside described sleeve.
Advantageous Effects of the present utility model is: the sleeve of bearing is made up of polytetrafluoroethylmaterial material, teflon has wear-resisting, the characteristic of antiacid alkali, the phenomenon that bearing rust is stuck can not be produced, in addition, the sleeve adopting polytetrafluoroethylmaterial material to make coordinates with axis of rotation, little compared with the friction factor of other nonmetallic material, rotational stability can be ensured, simultaneously, the end face of sleeve offers end face oil groove, ensure sleeve end face lubrication effect, the inwall of sleeve offers inside tank, when sleeve coordinates with axis of rotation, the lubrication object between sleeve and axle can not only be reached, and, inside tank also has appearance dirt, hold the function of bits, when there is dust in sleeve, dust can be gathered in inside tank, ensure that rotating shaft coordinates with stable between sleeve.Bearing fault rate in the utility model is lower, greatly reduces maintenance cost, increases economic efficiency.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of embodiment of the utility model;
Fig. 2 is the right elevation of Fig. 1.
Embodiment
The embodiment 1 of the utility model cutting machine delivering gear positioning device, delivering gear positioning device comprises bearing, as Fig. 1, shown in Fig. 2, this bearing is sleeve bearing, comprise the sleeve 1 be made up of polytetrafluoroethylmaterial material, the axis of sleeve 1 extends in left-right direction and its inner side surface is the face that is rotatably assorted 11 for coordinating with rotating shaft, sleeve is by the one-body molded setting of nonmetallic material, when delivering gear maintaining positioning device with when changing bearing, dismounting is more convenient, polytetrafluoroethylmaterial material is wear-resisting, there will not be the phenomenon that corrosion is stuck simultaneously, reduce the maintenance rate of equipment, save maintenance cost.
The right side of sleeve 1 offers the end face oil groove 2 of ring seal, the inwall of sleeve 1 offers the inside tank 3 of ring seal, the effect of sleeve and rotating shaft lubrication can not only be reached for, simultaneously, oil groove also has the function held dirt, hold bits, and can mainly be gathered in oil groove when dust or scrap enter after in bearing, the laying dust being positioned at oil groove can not affect the face that is rotatably assorted of sleeve and being rotatably assorted of rotating shaft, ensure the matching gap of sleeve and rotating shaft, operate steadily.The outside of sleeve 1 has positioning step 4, and the step surface of positioning step 4 is towards a left side, and during installation, positioning step can ensure that sleeve is in place.
The embodiment of the utility model bearing, as shown in Figure 1 and Figure 2, the structure of bearing is as above-mentioned, and for avoiding repetition, therefore not to repeat here.
Claims (4)
1. a bearing, is characterized in that: comprise the sleeve be made up of polytetrafluoroethylmaterial material, and the inner side surface of sleeve is the face of being rotatably assorted, and one in the both ends of the surface of sleeve offers end face oil groove, the inwall of sleeve offers inside tank.
2. bearing according to claim 1, is characterized in that: be provided with positioning step outside described sleeve.
3. a cutting machine delivering gear positioning device, comprises bearing, it is characterized in that: described bearing comprises the sleeve be made up of polytetrafluoroethylmaterial material, and one in the both ends of the surface of sleeve offers end face oil groove, the inwall of sleeve offers inside tank.
4. cutting machine delivering gear positioning device according to claim 3, is characterized in that: be provided with positioning step outside described sleeve.
