Abstract

The invention relates to a reversing speed reducer. A parallel input shaft extends out of a box body to connect a first hanging wheel, a first parallel intermediate shaft extends out of the box body to connect a second hanging wheel, the first and second hanging wheels engage for transmission, and the first The first and second pinions are arranged on the parallel intermediate shafts, the third pinion gears are arranged on the second parallel intermediate shafts, the first and second parallel intermediate shafts, the parallel input shafts, the output shafts are parallel, and the first and second parallel intermediate shafts, The parallel input shafts are not on the same horizontal plane, the second and third pinions are meshed, and the output shaft is connected to an adjusting bushing via a key sliding guide. A double gear is connected, and the two gears of the double gear are in a state where the adjustment shaft sleeve moves on the output shaft with the shifting fork through the shifting fork opening and is not meshed with the first and third pinions at the same time; the speed ratio of the first and second gears can be adjusted. replace. The structure is simple and compact, easy to use and adjust, and can meet the use requirements of various speed ratio outputs in a wide range.

Description

A kind of commutation variable speed reducer

Technical field

The present invention relates to a kind of speed reducer, specifically a kind of commutation variable speed reducer.

Background technique

The speed ratio of traditional speed reducer is fixed, even adjustable speed ratio speed reducer, and speed ratio is also that adjustment when leaving the factory is good, is led to It crosses and the engaging section of speed reducer internal drive is adjusted similar to shifting fork device, one to two be achieved in kind difference speed ratio is defeated Out, but the quantity of its speed ratio is still limited, and speed reducer internal drive can not be replaced, and has biggish limitation.

Summary of the invention

For speed change problem in the prior art, it is simple, compact that the present invention provides a kind of structures, and use, adjusting are convenient, The commutation variable speed reducer of a variety of speed ratios output in wider range can effectively be met.

The technical solution adopted by the present invention is that: a kind of commutation variable speed reducer, including it is cabinet, input bevel gear axis, parallel It is more than input shaft, level-one that parallel jackshaft and output shaft, input bevel gear axis are engaged in the bevel gear on parallel input shaft, It is characterized by: the parallel input shaft stretches out external first change gear of cabinet, the first parallel jackshaft stretches out cabinet external second Change gear, the first and second change gear engaged transmission, the first parallel jackshaft are equipped with the first and second pinion gear, set on the second parallel jackshaft There is a third pinion, the first and second parallel jackshaft, parallel input shaft, output shaft be parallel and the first and second parallel jackshaft, parallel Input shaft is not in same level, the engagement of second and third pinion gear, is socketed an adjustment axis through key slide-and-guide on output shaft Set, adjustment axis put on the shift fork mouth that external shift fork is arranged, and adjustment axis, which is put on, is keyed a duplicate gear, two teeth of duplicate gear Wheel stirs meshing state when adjustment axis is set on the output shaft mobile and the first and third pinion gear difference through shift fork mouth in shift fork；The One, two change gear speed ratios are replaceable.

The shift fork includes interior fork arm, rotation drive seat, drive shaft, driving handle, and rotation drive seat, which is worn, to be connect on cabinet, Drive seat inscribed interior fork arm, external driving handle are rotated, interior fork arm is plugged in shift fork mouth, and driving handle is worn to connect and be driven in rotation Drive shaft rotation in dynamic seat is drivingly connected interior fork arm.

The present invention uses external intermeshing first and second change gear of cabinet by parallel input shaft power transmission to jackshaft On, the first and second change gear can be replaced for the requirement of different speed ratios, input upper earlier adjustment member speed ratio in power, then tie Speed ratio needed for conjunction subsequent stage or multistage jackshaft transmission are exported through output shaft, structure is simple, compact, and use, adjusting are convenient, Meet the requirement of a variety of speed ratios output in wider range.
