Abstract
The utility model discloses a compressive creep's test device, the whole absolute construction who is the cuboid of this sample device goes up the pressure head and couples together through locating pin and test pressure machine, through the universal joint of embedded steel ball, to compressive creep sample applied load, has still increased pressure deformation pipe, can apply the power value of invariable homogeneous to the sample. This test device can be used for studying insulating material when the motor moves, receive working condition such as pressure, temperature and vibrations under, factors such as insulating material's the deformation condition, the atress condition and ageing life -span. This test device has simple and conveniently, and the practicality is strong, can simulate multiple operating mode, can carry on characteristics such as carrying out multinomial test. The device to the compressive creep characteristic research of material, has played important supplementary and supporting role.
Description
Technical field
The utility model relates to a kind of compression creep test device.
Background technology
Insulating material runs except playing insulating effect at motor, and time a lot of, insulating material also can play and support and the effect such as fastening.And in this process, insulating material can be subject to the factor impacts such as high temperature, high pressure and mechanical vibration, make insulating material accelerated deterioration, and then affect the serviceable life of insulating material and the security of operation of motor.Existing compression creep technology possesses following shortcoming: being fixed on testing equipment cannot independent operation; Single environment factor stimulation can only be completed, cannot multiple environmental factor carry out together; Lack the device in Pressure Maintenance System and adjustment direction.This utility model overcomes above technical disadvantages.Add universal knot so that effective adjustment compression creep load is to the force direction of sample, and then ensure that sample is subject to vertically descending force value.Meanwhile, also add pressure deformation pipe, thus can ensure that the force balance and stability of sample is homogeneous.This test unit can independently operate, and can carry various working condition simultaneously, such as: the environmental factors such as high temperature, vibrations, cold cycling, thus reaches working condition when simulated machine runs.
Summary of the invention
The object of the utility model patent openly a kind ofly effectively can solve the compression creep test device carrying various working condition, the technical solution of the utility model is: overall is absolute construction, seaming chuck (1) contacts with top board (2) face, but do not link together, seaming chuck (1) is connected with test pressure machine by register pin; The block (3) that is in transmission connection is welded on the center of top board (2).The gear train that universal knot (4) is embedded steel ball, the block (3) that is in transmission connection is fixed on universal knot (4) with transmission pressure head (5) mode embedded, with bolt, fixed frame (6) is fixed on lower platen (9) conjunction, pad (8) is placed on lower platen (9), regulate height, sample (7) is placed on pad (8), lower platen (9) is connected by bolt (10) and nut with top board (2), bolt (10) outer cover has deformation pressure pipe (11), deformation pressure pipe (11) is hydraulic means.
Technique effect
Be illustrated in figure 2 existing compression creep test device schematic diagram, by pressure head (1), compression creep load is applied to sample (2), sample (2) is placed on pressing plate (3), and is placed in environmental chamber (4) simultaneously.This compression creep technology possesses following shortcoming: being fixed on testing equipment cannot independent operation; Single environment factor stimulation can only be completed, cannot multiple environmental factor carry out together; Lack the device in Pressure Maintenance System and adjustment direction.
The utility model overcomes above technical disadvantages: add universal knot so that effective adjustment compression creep load is to the force direction of sample, and then ensure that sample is subject to vertically descending force value; Meanwhile, also add pressure deformation pipe, thus can ensure that the force balance and stability of sample is homogeneous; This test unit can independently operate, and can carry various working condition simultaneously, such as: the environmental factors such as high temperature, vibrations, cold cycling, thus reaches working condition when simulated machine runs.
