The technical scheme of the steam rolling bearing heater includes that the heater comprises a heater body (1), a steam inlet (8), a water outlet (9) and an upper end cover (7). The heater body is a container with an opening, the steam inlet arranged on the upper portion of the heater body is communicated with an annular sandwich wall layer of the heater body, the water outlet is arranged on the lower portion of the heater body, the upper end cover matches with the opening of the heater body, the steam inlet (8) is connected with an industrial steam pipeline (5) by the aid of a pipeline and a valve (6), the water outlet (9) is connected with a drainage pipeline (2) by the aid of a pipeline and a steam trap (3), and a bearing (4) needing heating is placed into the heater body from the upper opening. The steam rolling bearing heater has the advantages of simple and practical structure, low cost, capabilities of simultaneously heating a plurality of sets of bearings and leading bearing heating to be speedy and simple, high efficiency, greatly reduced labor intensity of staff, easy control of the temperature of the bearing heating, even temperature of the bearing heating, guarantee of assembly quality, no environmental pollution, improved working environment for the staff, avoidance of danger of catching fire and electric shock, guarantee of staff safety and great improvement in positive working attitude of the staff.
Description
Affiliated technical field:
When the utility model relates to the assembling of a kind of plant equipment rolling bearing to the heater of bearing, particularly in batches, concentrate the steam-type rolling bearing heater of assembling high-precision rolling bearing.
Background technology:
In machine-building and maintenance industry, the work of assembling rolling bearing is very general.For the assembly quality that guarantees bearing, improve efficiency of assembling and reduce labour intensity, need hot charging during being equipped with of rolling bearing, just before assembling, earlier bearing is heated.But should not surpass 100 ℃ to the bearing heating-up temperature, otherwise the structure of bearing material may change and cause the nonvolatil change in size of bearing.At present, Chang Yong bearing heating means have: high temperature oil bath heated mandrel holds; Oxygen--acetylene flame heating; Electrical heating.There is following shortcoming respectively in these three kinds of assembly methods: (1) high temperature oil bath heating is more dirty and messy, bearing is contaminated easily, and the back toxic gas of growing heat time heating time, burn is detrimental to health, and has fire hazard.(2) oxygen--the heating of acetylene flame does not have temperature control function, and the heating-up temperature inequality is very easily damaged bearing, can not unify to heat, and the heating preparation time is long, has fire hazard, produces toxic gas behind the burning protection oil and is detrimental to health.(3) electrical heating cost height, heat time heating time is long, the heater easy burn-out, the assembly crewman easily gets an electric shock.
The utility model content:
The utility model purpose provides a kind of steam-type rolling bearing heater, efficient height, assembly quality height, and safe and reliable, pollution-free, labour intensity is low, solves the problems referred to above that exist in the background technology.
The technical solution of the utility model is: steam-type rolling bearing heater comprises heater body, steam inlet, discharge outlet, upper end cover.Heater body is an open containers, and top is provided with steam inlet, and the bottom is provided with discharge outlet, and the opening of upper end cover and heater body is complementary.
Said steam inlet is connected with the industrial steam pipeline by pipeline, valve; Said discharge outlet is connected with drainage pipeline by pipeline, steam trap.
Said heater body is two different-diameters being nested together and the steel pipe of differing heights, forms a marmon clamp parietal layer, and the bottom is provided with double-deck blind plate shutoff, and marmon clamp parietal layer top is provided with the doughnut-shaped steel plate shutoff, and heater body upper shed capping has upper end cover.
Said upper end cover is the seal cover board of being made by heat-barrier material.
Adopt the utility model that rolling bearing is heated: to open upper end cover, bearing is put into heater body, build upper end cover, open valve industrial steam is fed in the wall-sandwiched layer of heater body.Open upper end cover after 15 minutes, both can begin assembling when reaching 100 ℃ with temperature measurer detection bearing temperature, the condensed water of vapours is discharged by drainage pipeline in the heater body.
The beneficial effects of the utility model are: simple and practical, cost is low; Can heat simultaneously many covers bearing, make the heating of bearing simple fast, the efficient height greatly reduces staff labor intensity; The bearing heating-up temperature is control and even easily, has guaranteed assembly quality; Non-environmental-pollution has improved employee's operating environment; Avoided the danger of catching fire and getting an electric shock, made Employee Security obtain guarantee, work incentive is greatly improved.
Description of drawings:
Accompanying drawing is the utility model example structure schematic diagram;
Among the figure: heater body 1, drainage pipeline 2, steam trap 3, rolling bearing 4, industrial steam pipeline 5, valve 6, upper end cover 7, steam inlet 8, discharge outlet 9.
The specific embodiment:
Below in conjunction with accompanying drawing, the utility model is described in further detail by embodiment.
In an embodiment, steam-type rolling bearing heater comprises heater body 1, steam inlet 8, discharge outlet 9, upper end cover 7, heater body is an open containers, top is provided with steam inlet, and the bottom is provided with discharge outlet, and the opening of upper end cover and heater body is complementary.Steam inlet 8 is connected with industrial steam pipeline 5 by pipeline, valve 6, and discharge outlet 9 is connected with drainage pipeline 2 by pipeline, steam trap 3.Heater body 1 is two different-diameters being nested together and the steel pipe of differing heights, form a marmon clamp parietal layer, the bottom is provided with double-deck blind plate shutoff, marmon clamp parietal layer top is provided with the doughnut-shaped steel plate shutoff, the heater body upper shed is by upper end cover 7 cappings, and upper end cover 7 is seal cover boards that heat-barrier material is made.
In the present embodiment to the rolling bearing heating means be: upper end cover 7 is opened, and rolling bearing 4 is put into heater body 1 by upper shed, builds upper end cover 7, opens valve 6 and feed industrial steam in the wall-sandwiched layer of heater body 1.Open upper end cover 7 after 15 minutes, both can begin assembling when reaching 100 ℃ with temperature measurer detection bearing temperature.If near the no drainage pipeline heater, because of the condensed water of in heating process, discharging seldom, also can directly be discharged into condensed water on the ground or be thrown in the container from steam trap 3 discharges.
