Abstract

PURPOSE:To obtain the sliding contact material having the oxidation of an alloy suppressed, wear resistance improved and contact resistivity stabilized at a low value, by adding limited amounts of specified metals such as Ti, Mn and Nb to a specified Ag-Mn alloy. CONSTITUTION:The sliding contact material prepared by adding 1-10wt% Zn and 0.5-2% in total, one or more of Li, Be, Mg, Al, Ca, Ti, Mn, Fe, Y, Nb and Ta to Ag. According to the contact material having said composition, the formation of ZnO is suppressed by the oxidation of the added elements, the sulfurization resistance and lubricativity of the Ag-Zn alloy itself are maintained, wear resistance is improved, and contact resistivity is stabilized at a low value. When a contact piece for the commutator of a small-sized motor is made using said material, the effect to reduce the dispersion of the rotation number of the commutator, etc. are obtained.

【発明の詳細な説明】 本発明は、摺動接点材料の改良に関する。[Detailed description of the invention] The present invention relates to improvements in sliding contact materials.

Although ftAg-Zn alloy has been used because of its excellent lubricity, the sliding 11-point material of Ag-Zn alloy is easily oxidized.
The disadvantage is that the contact resistance is high and unstable, so when this sliding contact material is used to make a contact piece tube for the outer circumference of the commutator of a small motor, the contact resistance with the brush contact changes. However, the rotational speed of the commutator varied widely and became unstable.

The present invention solves this problem! : It was made to eliminate the scales of X1r, suppresses oxidation of the Ag-Zn alloy, maintains sulfidation resistance and lubricity, improves abrasion resistance, and also maintains low and stable contact resistance, resulting in large sliding contact. Ingredients 1 - The tortoise we are trying to provide.

The reason why these elements are more easily oxidized than Zn is to add at least 0.5 #2''/ to the total of at least one type of tube. Oxidation in the g-Zn alloy is suppressed, that is, the oxidation of the added elements suppresses the formation of ZnO, and the sulfidation resistance and lubricity of the Ag-Zn alloy are maintained, resulting in improved wear resistance. This is because the contact resistance is low and stable at the same time as the contact resistance is improved, and is 0.s'W/.

If it is less than that, oxidation in the A g -Z n alloy is not suppressed,
If the contact resistance exceeds 2W/), the properties of the Ag-Zn alloy such as sulfidation resistance and lubricity will decrease, so In the end, it is necessary to add 0.5 to 24.

As shown in the drawings, a small motor with a diameter of 6 m and a length of 9-Ag-Cu was prepared using the sliding contact material of the embodiment of the present invention and the conventional sliding contact material having the composition shown in the right column of the table below. -P
The three brush wires 21 having a diameter of 0.25 M and a length of 10 cm made of t were brought into sliding contact with each other at three points i, and a commutator rotation test was performed for 10 times under the test conditions described below. , the wear amount of the contact piece 1a and the variation in the commutator 10 rotation speed 1&
The results were obtained as shown in the right column of the table below.

Test conditions Voltage: 12 ■ Current: DC@QmA Commutator rotation speed: 2800 rpm As is clear from the table above, the amount of wear of the contact piece in the conventional example was 5 to 7 μ, whereas in the example II The amount of skin flakes wasted! Ri-3,0
It can be seen that there is a significant decrease in μ, indicating that the wear resistance is excellent. The variation in the rotation speed of the commutator with contact pieces in the conventional example was 8 to 11-1, while the variation in the rotation speed of the commutator with 11 contact pieces in the example was 3 #6. It can be seen that there is a significant decrease in This is simply because the oxidation of the 1# point piece of the example is suppressed by the Ag-Zn alloy, and the contact resistance is low and stable.
