Abstract
The utility model discloses a bearing heater. The bearing heater comprises an electric control cabinet, the electric control cabinet is equipped with U-shaped iron, end faces of two vertical columns of the U-shaped iron is provided with a yoke, the yoke is internally provided with a coil heating rod, and one end of the yoke is movably connected with a connecting rod on the electric control cabinet. The bearing heater solves the problems of the prior art that heating temperature is not easy to control and the cost is high, and has the characteristics of simple structure and high efficiency, is mainly used for heating various metal pieces, including bearings, gears, linings, diameter rings, pulleys, contraction rings, connectors and the like, and heating enables the metal pieces to expand, so as to meet the requirement for interference fitting.
Description
Technical field
Heater when the utility model relates to a kind of rolling bearing assembling,
Background technology
The hot charging matching method is adopted in the assembling of rolling bearing mostly, and it is to carry out interference fit by allowing two parts to be cooperated obtain different temperature, thereby makes assembling easier.External diameter surpasses the permanent bearing of 100mm, must heat whole bearing or bearing inner race according to mode of heating, makes interior ring easily be nested into axle.At present, the method for heating bearing also has the modes such as hot plate, steam, baking box except the most frequently used hot oil bath.The heating-up temperature that these methods have is wayward, and some costs are high.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of heating-up temperature bearing heater easy to control, simple in structure.
For solving the problems of the technologies described above, bearing heater of the present utility model comprises electric cabinet, U-iron is installed on the electric cabinet, place yoke on the end face of two columns of this U-iron, the coil heating rod is installed in the yoke, an end of yoke and the connecting rod on the electric cabinet are flexibly connected.
Because technique scheme adopts U-iron, yoke and coil heats bar construction electromagnetic induction heater, when the conductors such as bearing were placed on the yoke, the bearing cutting alternation magnetic line of force produced heat energy, thereby is heated, and can control degree of heating by electric cabinet.Therefore, the utlity model has the characteristics that heating-up temperature is easy to control, simple in structure, efficient is high, be mainly used in polytype metalworks such as bearing, gear, lining, diameter ring, pulley, contractile ring, connector are heated, make it to expand by heating, reach the needs of interference assembling.
Description of drawings
Accompanying drawing is the structural representation of the utility model bearing heater.
Embodiment
Bearing heater of the present utility model comprises electric cabinet 1, and U-iron 2 is installed on the electric cabinet 1, places yoke 3 on the end face of two columns of this U-iron 2, yoke 3 interior installation coil heating rods 4, and an end of yoke 3 and the connecting rod on the electric cabinet 15 are flexibly connected.
Using method of the present utility model is: corresponding yoke is placed on the end face of main frame, plug is inserted with in the supply socket of control switch, check whether earth connection is good, test with test pencil after the energising.The control switch that closes, this moment, indicator light was bright.Press start button, the main frame energising, this moment, run indicator was bright.The inspection yoke is answered no-voltage over the ground.Press the outage of stop button main frame.According to bearing or other workpiece of different size, select different yokes to put, this yoke is placed on the main frame top end face, should coincide smooth.
According to requirements of one's work, when selecting the temperature control shelves, temperature sensor should be inserted the sensing socket on the electric cabinet, and transducer is close to heated parts.When bearing heating to required temperature or the time, then stopped heating clicks shutdown switch automatically.
The ball bearing heating-up temperature is sure not above 150 ℃.Otherwise can cause bearing annealing.In order to improve the efficiency of heating surface, during according to the corresponding yoke of brearing bore size Selection, should use the larger yoke of sectional area as far as possible.
Main frame must smooth placement be sure not, and the end face of two columns of yoke and U-iron must coincide.Must after the main frame outage, can get the heating rod in the yoke.
