Abstract
The utility model provides a bogie axle box spring for an electricity multiple unit, which is characterized in that a spring set is composed of an inner spring (1) sleeved in an outer spring (2), and the winding direction of the inner spring (1) is opposite to the winding direction of the outer spring (2); both the inner spring (1) and the outer spring (2) have an outer shape of a cylindrate uniform pitch cylindroid helical-coil compression spring; the section shapes of both the effective coil section in the middle part of the inner spring (7) and the effective coil section in the middle part of the outer spring (8) are round, and both the end part support coil section of the inner spring (9) and the end part support coil section of the outer spring (10) are rectangular; and the round shapes of the effective coil section in the middle part of the inner spring (7) and the effective coil section in the middle part of the outer spring (8) transit to the rectangular shapes of the end part support coil section of the inner spring (9) and the end part support coil section of the outer spring (10). Compared with the prior bogie axle box spring applied to the electricity multiple units with the speed of 300km/h, the utility model has the advantages of small thermal deformation, long service life, labor-saving, raw material saving and the like.
Description
Technical field
The utility model relates to a kind of spring, especially a kind of motor train unit truck journal box spring.
Background technology
Spring is to use a kind of very widely parts in the machinery, existing spring mostly is cylindrical helical compression formula, its bracing ring adopts grinding machine directly to polish, this spring strength is poor, yielding, can only satisfy logical mechanical occasion use of former times, on the motor train unit of high-speed cruising, use yielding damage, useless worker, waste material.
Summary of the invention
This uses later-model purpose is to overcome above-mentioned spring weak point, a kind of intensity height is provided, be out of shape little, the technical scheme that its technical matters that solves the motor train unit truck journal box spring that can be used for motor train unit, the utility model adopts is: it comprises inner spring and outer spring, it is characterized in that inner spring is sleeved in the outer spring, constitute spring assembly, and the inner spring winding direction is opposite with the spring winding direction of outer spring, can make spring stress even like this, supports steadily.The gabarit shape of interior outer spring is the constant pitch cylindrical shape.Interior outer spring middle part is active coils. both ends are bracing ring.The active coils section form is circular, and bracing ring is a rectangle, and is gradually excessively to the rectangular cross section at both ends by the circular cross section at middle part.
The utility model is compared in 300 kilometers motor train unit truck journal boxs of speed per hour spring with existing application, and it is little to have a thermal deformation, long service life, advantages such as saving of labor, material-saving.
Description of drawings
Just figure is a structural representation of the present utility model.
Among the figure, 1, inner spring, 2, outer spring, 3, inner spring middle part active coils, 4, outer spring middle part active coils, 5, inner spring end portion supports circle, 6, outer spring end portion supports circle, 7, inner spring middle part active coils section, 8, outer spring middle part active coils section, 9, inner spring end portion supports circle section, 10, outer spring end portion supports circle section.
The specific embodiment
With reference to Figure of description, utility model motor train unit truck journal box spring is described further: as shown in the figure, motor train unit truck journal box spring includes inner spring 1 and outer spring 2, it is characterized in that inner spring 1 is sleeved in the outer spring 2, constitute spring assembly, and inner spring 1 winding direction is opposite with the spring winding direction of outer spring 2, and what provide in the accompanying drawings is that the winding direction of inner spring 1 is left-handed, and the winding direction of outer spring 2 is dextrorotation.The gabarit of inner spring 1 and outer spring 2 is shaped as spiral shell square cylinder compression coil springs such as cylindrical shape, the end that the middle part of inner spring 1 and outer spring 2 is respectively inner spring middle part active coils 3 and outer spring middle part active coils 4. inner springs 1 is an inner spring end portion supports circle 5, the end of outer spring 2 is an outer spring end portion supports circle 6, the section form of inner spring middle part active coils section 7 and outer spring middle part active coils section 8 is circle, inner spring end portion supports circle section 9 and outer spring end portion supports circle section 10 are rectangle, and the circle of inner spring middle part active coils section 7 and outer spring middle part active coils section 8 carries out the transition to the inner spring end portion supports circle section 9 and the outer spring end portion supports circle section 10 of rectangle gradually.This spring is to utilize the manufacturing of fulling technology, utilizes grinding machine to polish moulding then.
Claims (3)
1, a kind of motor train unit truck journal box spring, include inner spring (1) and outer spring (2), it is characterized in that inner spring (1) is sleeved in the outer spring (2), constitute spring assembly, and inner spring (1) winding direction is opposite with the spring winding direction of outer spring (2), and the gabarit of inner spring (1) and outer spring (2) is shaped as spiral shell square cylinder compression coil springs such as cylindrical shape.
2, according to the said motor train unit truck journal box of claim 1 spring, the middle part that it is characterized in that inner spring (1) and outer spring (2) is respectively inner spring middle part active coils (3) and outer spring middle part active coils (4), the end of inner spring (1) is an inner spring end portion supports circle (5), the end of outer spring (2) is an outer spring end portion supports circle (6), the section form of inner spring middle part active coils section (7) and outer spring middle part active coils section (8) is circle, and inner spring end portion supports circle section (9) and outer spring end portion supports circle section (10) are rectangle.
3,, it is characterized in that the circle of inner spring middle part active coils section (7) and outer spring middle part active coils section (8) carries out the transition to the inner spring end portion supports circle section (9) and the outer spring end portion supports circle section (10) of rectangle gradually according to the said motor train unit truck journal box of claim 2 spring.
