Abstract
The invention relates to a novel speed reducer with a torsion limitation function. A final gear is arranged on an output shaft in a gear box through a common bearing, one end surface of a friction disc is conic, and the friction disc is arranged on the output shaft at one side of the final gear through a key. When the friction disc is arranged, the degree of freedom of axially sliding along the output shaft needs to be ensured. An inner conic surface with the same conic degree with the end surface of the friction disc is arranged at one surface of the final gear, which corresponds to the friction disc. Two plane bearings are simultaneously arranged on the output shaft, one of the plane bearings lies against the left side of the friction disc, and the other plane bearing lies against the inner right side of the box body of the gear box. A spring is previously arranged on the output shaft between the two plane bearings, and the friction disc is combined with the final gear by the spring through one plane bearing and the upper conic surface of the friction disc. After the parts are arranged on the output shaft, the output shaft is arranged on the gear box through the bearing of the output shaft.
Description
Technical field
The present invention relates to a kind of retarder, particularly a kind of retarder of novel limited torque function belongs to the mechanical transmissioning technology field.
Background technique
Retarder is a kind of important transmission part in the mechanical transmission, and at present, in the product of retarder, retarder is as just the transmission part of power, owing to there is not the limitation function of moment of torsion, tends to occur the accident of damaging component of machine after the overburdening and takes place.
Summary of the invention
The objective of the invention is to: a kind of retarder of novel limited torque function is provided, overcomes existing retarder, cause the defective of machinery damage of components after the overload easily owing to there is not the limited torque function existing.
The present invention realizes that the technological scheme that above-mentioned purpose adopts is: be installed in the final stage gear above the output shaft of gear-box inside by plain bearing, one end face of described friction disk is tapered, friction disk is installed in above the output shaft of final stage gear one side by key, will demonstrate,prove friction disk during installation has along output shaft degrees of freedom in axial sliding, and not with output shaft degrees of freedom in relative rotation, in final stage gear and the corresponding one side of friction disk, produce and the identical inner conical surface of friction disk end face tapering, with two plane bearings be installed in simultaneously output shaft above, be close together with left side friction disk wherein a kind of, an interior right side with gear case body in addition is close together, mounting spring above the output shaft between two plane bearings in advance, spring passes through a plane bearing wherein, friction disk and final stage gear are combined tightly by on one's body the conical surface separately, after on output shaft, installing above-mentioned parts, by output shaft bearing with output shaft be installed in gear-box above.
Beneficial effect: as can be seen from working principle of the present invention; the gear that is meshed with the final stage gear; give the final stage gear with transmission of power; the final stage gear by and friction disk between frictional force; power is passed to friction disk; because friction disk is connected by key with output shaft; there is not the degrees of freedom of rotating each other; so; output shaft just rotates under the transmission of final stage gear; once the external load of output shaft surpasses certain limit; then just begin to skid between friction disk and the final stage gear, thereby reach the purpose of overload protection, simultaneously; also can overcome existing retarder owing to there is not the limited torque function existing, cause the defective of the damage of machinery component after the overload easily.
