Abstract
The invention discloses a seamer without lubricate bearing, which is characterized by the following: the non-lubricate bearing is composed of inner case with metal sleeve and macromolecular composite material, which is inserted in the outer case; the cooling groove is set between inner and outer surface; the macromolecular composite material of non-lubricate bearing inner case is composed of metaformaldehyde, 3-45 percent solid lubricate and 10-30 percent mine fiber or carbon fiber; the solid lubricate is composed of 3-15 percent politef, 3-20 percent molybdenum disulfide, 10-45 percent graphite. The invention solves pollution problem of seaming cloth completely.
Description
Technical field
The present invention relates to industrial sewing machine, specifically refer to a kind of Sewing machines that adopts Nonlubricated bearing.
Background technology
The sliding bearing of traditional Sewing machines all can only could run well under the situation of fuel feeding always.In case oil-break, axle raises rapidly because of friction temperature with bearing and kills very soon; On the other hand, lubricating oil can leak out from fray, makes the fabric of being made contaminated, causes waster, has a strong impact on the result of use of Sewing machines.
Summary of the invention
The objective of the invention is to propose a kind of sewing machine without oil lubrication, bearings such as the last axle bearing of this Sewing machines, lower shaft bearing and shank bearing all adopt no cunning dynamic bearing, thereby overcome the shortcoming of prior art.
A kind of sewing machine without oil lubrication of the present invention, the bearing that it is characterized in that described Sewing machines adopts Nonlubricated bearing, the interior cover that described Nonlubricated bearing is made by metal-coating and polymer composite is formed, in be locked and be set in the overcoat, be provided with cooling bath at the inner surface of interior cover.
The polymer composite of making the interior cover of Nonlubricated bearing in the described sewing machine without oil lubrication is reached by polyformaldehyde, kollag to be formed based on the fiber-like material of mineral fibres or carbon fiber, by weight, kollag accounts for 3-45%, mineral fibres or carbon fiber account for 10-30%, and all the other are polyformaldehyde.Wherein kollag can be polytetrafluoroethylene (PTFE) or molybdenum bisuphide or graphite, and by weight, the addition of polytetrafluoroethylene (PTFE) is 3-15%, and molybdenum bisuphide is 3-20%, and graphite is 10-45%.
The invention has the advantages that because the coefficient of friction of cover is extremely low in the described Nonlubricated bearing, anti-wear performance is fabulous, axle is when the surface runs up within it, can not produce high temperature, not easy to wear yet, thereby adopt Nonlubricated bearing can adapt to operate as normal under the no oily condition.After using Nonlubricated bearing, both thoroughly solve the pollution problem of being made fabric, reduced pollution again, saved the energy.
Description of drawings
Now the invention will be further described in conjunction with some embodiment and accompanying drawing.
Fig. 1 is the structural representation of sewing machine without oil lubrication of the present invention;
Fig. 2 is the structural representation of Nonlubricated bearing.
Among the figure: 1 fuselage, axle on 2,3 lower shafts, 4 vertical pivots, 5 shanks, axle bearing on 7,8,9,10,11 lower shaft bearings, 12,13 vertical pivot bearings, 14,15 shank bearings, 21 bearing outsides, 22 bearing inner sleeves, 23 cooling baths.
The specific embodiment
Embodiment 1
As shown in Figure 1, on axle 2 on the Sewing machines, be provided with and be provided with bearing 10,11 on bearing 7,8,9, the lower shaft 3, vertical pivot 4 is provided with vertical pivot bearing 12,13, shank 5 is provided with shank bearing 14,15, all these bearings all adopt Nonlubricated bearing, and the bearing that uses in other kinematic pair also replaces with Nonlubricated bearing.
The structure of described Nonlubricated bearing is made up of the interior cover 22 that metal-coating 21 and polymer composite are made as shown in Figure 2, in be locked and be set in the overcoat, on the inner surface of interior cover, be provided with cooling bath 3.
Embodiment 2-7
The composition (weight %) of making the polymer composite of cover in the Nonlubricated bearing is as shown in table 1.
