Abstract
The invention relates to a bearing heater which consists of a housing, an insulating heat conduction layer, a conducting film, an elastic support, a heating resistor (PTC heating chip), a strong magnetic strip and a wire. The housing is lined with the strong magnetic strip, the PTC heating chip is arranged in the housing, the PTC heating chip is wrapped in the insulating heat conduction layer, the conducting film is laid between the PTC heating chip and the insulating heat conduction layer, the elastic support is arranged between the housing and the insulating heat conduction layer, and the conducting film is connected with the wire. The bearing heater is small in volume, light in weight, simple in structure and convenient in operation and is easy to carry and not restricted by the size of site; the heating process has no naked flame, noise or pollution, the heater is safe and reliable to use, can reduce the heating cost and has low requirement on voltage; the real-time power of heating is related to the temperature of heater, the number of heaters can be determined according to the bearing size; the bearing heater has good applicability, can not only be used for bearing assembling, but also can be used for bearing dismantling.
Description
Technical field
The invention belongs to the electric heating equipment field, be specifically related to a kind of Bearing Installation and heater in when dismounting of being used for.
Background technology
The Assembly And Disassembly of bearing is the work of not only taking a lot of work but also wasting time and energy, and method and shortcoming thereof that bearing assembling at present and dismounting are taked are:
1, knock: noise is big, operator's labour intensity is big, and defective work piece very easily.
2, machine is pressed: equipment is heavy, and reduces the precision of mating surface, influences result of use.
3, flame heat: temperature is wayward, fragile workpiece.
4, oil boils: heating time is long, difficult control of temperature, and energy consumption is serious, reduces workpiece accuracy, contaminated environment, and can only install, can not dismantle.
5, high-frequency electromagnetic induction heating: be present most popular mode, its equipment is heavy, and complex structure costs an arm and a leg, and there is inevitably stealthy injury in its frequency electromagnetic waves to people and equipment.
6, adopt heating cabinet, heating cabinet: volume is heavy, and complex structure costs an arm and a leg, and is not easy to carry.Also Bearing Installation can only be used for, bearing removal can not be carried out.
Summary of the invention
The object of the present invention is to provide a kind of simplely, safe and reliable, be easy to carry and operate, the flames of anger, noiselessness, pollution-free, programming rate is fast, can reduce the heating expense, and heater is used in strong bearing assembling, the dismounting of applicability.
The technical solution that the present invention taked is:
A kind of bearing heater; It is characterized in that; Said heater is that PTC heating chip, strong magnetic stripe and lead are formed by shell, insulating heat-conductive layer, conducting film, elasticity support, heating resistor, on two long limits of flat-square shaped metal shell, respectively studs with a strong magnetic stripe, is provided with sheet PTC heating chip in the shell; PTC heating chip outerwrap insulating heat-conductive layer; Lay conducting film between PTC heating chip and the insulating heat-conductive layer, the elasticity support is housed in the space between shell and the insulating heat-conductive layer upper surface, conducting film one end connects the lead that has attaching plug.
Be filled with insulation filler in the space between said shell and the insulating heat-conductive layer.
The Curie temperature of said PTC heating chip is 85～180 ℃.
Method for using of the present invention and beneficial effect are:
During use, the heating surface (promptly studding with the one side of strong magnetic stripe) of heater is put on bearing two side planes, strong magnetic stripe can hold bearing being adsorbed on the bearing heater.If bearing is bigger, can increase heater quantity.After heater was put well, insulation things such as available cotton-wadded quilt encased bearing, to prevent heat dissipation.Then, send electricity to heater, treat that bearing is heated to the Curie temperature value after, can carry out bearing removal or Bearing Installation.
The present invention's bearing heater adopts the PTC heating chip to carry out electric heating, overcomes the defective of existing bearing mode of heating effectively, and it is little, in light weight, simple in structure to have a volume, and operation is convenient, is easy to carry, and does not receive place size restriction; The heating process flames of anger, noiselessness, pollution-free, safe and reliable, reduce heating cost; And it is not high to voltage request; The realtime power of heating is relevant with the temperature of heater, can confirm the heater quantity of use according to bearing size, and applicability is strong; Not only can be used for the bearing assembling, also can be used for bearing removal.
Description of drawings
Fig. 1 is a bearing heater master pseudosection.
Fig. 2 is the bearing heater vertical view.
Fig. 3 is the bearing heater left view.
Fig. 4 is a bearing heater user mode sketch map.
Among the figure: shell 1, insulating heat-conductive layer 2, conducting film 3, elasticity support 4, lead 5, plug 6, insulation filler 7, PTC heating chip 8, strong magnetic stripe 9, heater 10, bearing 11.
Embodiment
Visible by accompanying drawing, bearing heater 10 of the present invention mainly is made up of shell 1, insulating heat-conductive layer 2, conducting film 3, elasticity support 4, lead 5, plug 6, PTC heating chip 8, strong 9 of magnetic stripes.
Be the reinforced insulation effect, improve the fail safe that heater uses, also can in the space between shell 1 and the insulating heat-conductive layer 2, load certain insulation filler 7.
Fig. 4 is a bearing heater user mode sketch map, the example that is merely four heaters 10 of use of its expression.The usage quantity of heater 10 need be that the size of surface area is confirmed according to the size of bearing 11.For little bearing 11, use a heater 10 to get final product; Big bearing 11 then need use a plurality of heaters 10.Definite principle of its usage quantity is can lay down heater 10 with bearing 11 surfaces to be as the criterion.Both can lay at the single face of bearing 11, and also can lay simultaneously on the two sides of bearing 11, concrete method for using is selected flexibly according to field condition and heating time.
