Body is wider, be also easy to produce in operation input shaft distortion it is big, so as to influence the noise of complete machine and service life, input shaft end transmission size is small,
Wasting space is larger, the big bearing life for influencing input gear axle of body span.
Invention content
It is long to provide a kind of low noise, service life for the utility model to solve the above-mentioned problems, while production cost is low
Parallel-axes gears retarder drive mechanism.
The utility model is achieved through the following technical solutions in order to achieve the above object：
The utility model is a kind of drive mechanism of parallel-axes gears retarder, including body, cover, one-stage gear axis,
Secondary gear wheel shaft and tertiary gear axis, tertiary gear axis and one-stage gear axis coaxial centerline, one-stage gear axis and backgear phase
Engagement, transfers torque to secondary gear wheel shaft, secondary gear wheel shaft is engaged with front gear transfers torque to three-level by the second flat key
Gear shaft, front gear are connected by the first flat key with tertiary gear axis, and fixed tertiary gear axis and level-one are provided in body
The bearing block of gear shaft is fixed with the rear bearing and fore bearing of one-stage gear axis and tertiary gear shaft end, axis in bearing block
Bearing is connected by taper bolt, bolt with bearing cap.
Further improvement of the utility model is：Being provided on bearing cap 14 being capable of sufficient lubrication fore bearing and rear axle
The oil trap held.
Further improvement of the utility model is：Taper roll bearing 9 is provided at both ends in secondary gear wheel shaft 8.
Further improvement of the utility model is：It is equipped on bearing block 12 and wears axis hole and oil-through hole.
The beneficial effects of the utility model are：The utility model increases the input gear axle diameter of axle, reduces the generation of deformation,
Noise is reduced, the utility model realizes three-level transmission in the space of primary transmission, and structure closely, increases input gear
The service life of axis bearings at both ends reduces the deformation of input gear axle, improves complete machine reliability of operation, reduces manufacture
Difficulty, production cost are low.
