Description
Technical field:
The utility model relates to the bearing apparatus technical field, more specifically to the detachable viewing window of a kind of New type ventilating.
Background technique:
Sliding bearing (band oil ring) in use, sometimes needs bearing inside oil ring running is observed, and oil ring self oiling bearing especially can reliable operation to guarantee bearing.Therefore, the sliding bearing top is often with viewing window.But the viewing window of bearing employing at present is all generally plastic material, and of long duration easy to be fuzzy, observing effect is undesirable, and dismounting is inconvenient, easily damages.
The model utility content:
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of simple in structure, observing effect is remarkable, the detachable viewing window of New type ventilating of safe and reliable easy dismounting cleaning.
The scheme that the utility model solve the technical problem is:
The detachable viewing window of a kind of New type ventilating, comprise the observation forms, in described observation forms, form axial ladder hole, ladder hole comprises top the first shoulder hole section and bottom the second shoulder hole section, the diameter of the first shoulder hole section is greater than the second shoulder hole section, in the first shoulder hole section, be inserted with successively the first packing ring, sight glass and the second packing ring, the top of the first shoulder hole section is bolted with trim ring, trim ring is pressed against on the second packing ring, sight glass is clamped between the first packing ring and the second packing ring, and the first packing ring is pressed against on the bottom end of the first shoulder hole section.
Left side and the right side of the top sidewall of described the second shoulder hole section all form breach, breach communicates with the first shoulder hole section, left side and the right side of observing the top of forms all form radial direction through hole, and an end of radial direction through hole communicates with the external world, the other end communicates with the first shoulder hole section.
The upper and lower of described trim ring upper-end surface all forms radial groove.
The top of described observation forms is that hexagonal cylinder, bottom are cylindrical body, forms annular groove on cylindrical external wall of upper portion, forms outside thread on the outer wall of cylindrical bottom, and the sealing gasket sleeve is on cylindrical external wall of upper portion.
Outstanding effect of the present utility model is:
Compared with prior art, it is simple in structure, and it is clear that observation facilitates, and easily dismounting, as long as just sight glass can be unloaded after trim ring is back-outed, clear up, simultaneously, its radial direction through hole communicates with the external world, make this observation forms internal ventilation, make like this internal and external pressure balance, temperature is identical, can not produce because internal-external temperature difference causes greatly the problem that sight glass is fuzzy.
The accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the A-A sectional view of Fig. 1.
Embodiment:
Embodiment, see illustrated in figures 1 and 2, the detachable viewing window of a kind of New type ventilating, comprise and observe forms 1, in described observation forms 1, form axial ladder hole 2, ladder hole 2 comprises top the first shoulder hole section 21 and bottom the second shoulder hole section 22, the diameter of the first shoulder hole section 21 is greater than the second shoulder hole section 22, in the first shoulder hole section 21, be inserted with successively the first packing ring 3, sight glass 4 and the second packing ring 5, the top of the first shoulder hole section 21 is bolted with trim ring 6, trim ring 6 is pressed against on the second packing ring 5, sight glass 4 is clamped between the first packing ring 3 and the second packing ring 5, the first packing ring 3 is pressed against on the bottom end of the first shoulder hole section 21.
Left side and the right side of the top sidewall of described the second shoulder hole section 22 all form breach 23, breach 23 communicates with the first shoulder hole section 21, left side and the right side of observing the top of forms 4 all form radial direction through hole 41, one end of radial direction through hole 41 communicates with the external world, the other end communicates with the first shoulder hole section 21, and the diameter of the first packing ring 3, sight glass 4 and the second packing ring 5 all is less than the diameter of the first shoulder hole section 21.
The upper and lower of described trim ring 6 upper-end surfaces all forms radial groove 61.
The top of described observation forms 1 is that hexagonal cylinder 11, bottom are cylindrical body 12, the first shoulder hole section 21 is in hexagonal cylinder 11, the second shoulder hole section 22 is in cylindrical body 12, on the external wall of upper portion of cylindrical body 12, form annular groove 13, on the bottom outer wall of cylindrical body 12, form outside thread, sealing gasket 7 sleeves are on the external wall of upper portion of cylindrical body 12.
Working principle: the lower cylindrical body 12 of this observation forms 1 is screwed on the joint of bearing apparatus, makes sealing gasket 7 be clamped in to observe between the joint end face of the bottom end of top hexagonal cylinder 11 of forms 1 and bearing apparatus.
By trim ring 6, see the working order of the bearing ring that sight glass 4 is following.
Two radial grooves 61 of trim ring 6 can facilitate a word bottle opener rotation trim ring 6, and trim ring 6 is screwed onto in the first shoulder hole section 21 of observing forms 1 or from the first shoulder hole section 21, unloading.
