The invention discloses a friction plate for a speed reducer. The friction plate comprises a friction plate body; an assembling hole is formed in the center of the friction plate body; the friction plate body comprises a steel base plate and copper base plates on two sides of the steel base plate; oil grooves are formed in the outer surfaces of the copper base plates and adopt crossed double-arc-shaped structures; two ends of each oil groove extend to the edges of the corresponding copper base plate, and openings are formed in the edges; and circles where the central lines of the oil grooves are located pass through the central point of the friction plate body. The friction plate has the advantages as follows: the friction plate is simple in structure, the composite structure comprising the steel base plate and the copper base plates is adopted, and thus the overall strength is improved while the surface wear resistance is guaranteed; and the oil grooves adopting the crossed double-arc-shaped structures are formed in the outer surfaces of the copper base plates, the friction plate is cooled during braking, the friction temperature rise of the friction plate can be effectively reduced, the central lines of the oil grooves pass through the circle centers, the flowing speed of oil can be increased, and the cooling effect can be improved.
Description
technical field [0001] The invention relates to spare parts of a speed reducer, in particular to a friction plate for a speed reducer, in particular to a friction plate used in a walking and turning speed reducer. Background technique [0002] The friction plate used in the walking and slewing reducer plays the role of braking and stopping when stopping or changing direction. In order to ensure timely shutdown and reversing, reliable braking and long service life of the friction disc are required. However, due to the large inertia during braking, the traditional paper-based friction plate has a large temperature rise, wears quickly, and has a short life, requiring frequent maintenance and replacement. The stability and continuity of the operation of the whole equipment. [0003] The existing application number is 201120410798.9, and the patent titled "a friction plate" discloses a friction plate, which has an annular disc-shaped core plate, and the outer or inner edge of t...
