Abstract
The utility model discloses a double-staged high efficient variable gear for an automobile and aims to solve problems of high machining precision of a double-output variable gear, complicate assembling, difficult after-sale services and large energy requirements as well as large fuel consumption in the prior art. A traditional motion method is changed; a double-output variable gear is sleeved on a gear shaft; an installation bearing is mounted between the double-output variable gear and the gear shaft; the gear shaft is inserted into a gearbox housing; a part of the gear shaft between the double-output variable gear and the gearbox housing is covered with a stop sleeve; and a gasket is arranged between the stop sleeve and the double-output variable gear. Two gears with different diameters of the double-output variable gear are integrated, thereby avoiding two needle bearings each containing an external ring and two stop bearings, so the above deficiencies in the prior art can be well overcome.
Description
Technical field
The utility model relates to auto parts and components, particularly relates to the efficient speed change gear of automobile two-stage.
Background technique
In the prior art, automobile is structure as a whole with dual output speed change gear and the gear shaft of the efficient speed change gear of two-stage, in gearbox, rotate with respect to gear box casing, dual output speed change gear is two gears that diameter differs, and this two gear makes automobile produce different gait of march while work separately.Because needs dual output speed change gear rotates with respect to gear box casing, therefore between gear shaft and gear box casing, adopt the needle bearing with outer ring to carry out radial location, adopt clamping stopper bearing to carry out axially locating.When assembling, need first press-fit the needle bearing of band outer ring, two ends, refill and join thrust bearing, last assembling gear assembly.Because the dual output speed change gear of this structure needs two needle bearing and two clamping stopper bearings with outer ring, cost is high on the one hand, between gear box casing and gear shaft, need to press-fit the needle bearing with outer ring, high to gear box casing housing bore and gear shaft requirement on machining accuracy, and needle bearing with outer ring need press-fit, assembling is complicated, reprocesses difficulty large; On the other hand, whole gear shaft and himself subsidiary dual output speed change gear together rotate, and the energy needing is larger, is also unfavorable for reducing the oil consumption of automobile.
Model utility content
For the problems referred to above, the utility model provides automobile two-stage efficient speed change gear, and it is simple in structure, easily assembling and can effectively reduce oil consumption.
The technological scheme that the utility model is taked is:
The efficient speed change gear of two-stage for automobile, comprises gear shaft, gear box casing and dual output speed change gear, and dual output speed change gear is sleeved on gear shaft, between described dual output speed change gear and gear shaft, bearing is installed; Gear bush is contained in gear box casing, and the part cover on gear shaft between dual output speed change gear and gear box casing has stop sleeve, between stop sleeve and dual output speed change gear, is provided with packing ring; Described dual output speed change gear is the gears that two diameters do not wait, and two gears are coaxial and be processed as one.
For further improving the operational efficiency of bearing, described bearing is needle bearing.
For dual output speed change gear is rotated with respect to gear box casing, gear box casing is inserted at the two ends of described gear shaft, and at least one end and gear box casing riveted joint of gear shaft.
The convenience of dismounting while maintenance for convenience of described dual output speed change gear, the riveted joint between described gear shaft and gear box casing adopts screw or bolt to be connected.
For preventing that dual output speed change gear from axial float occurring on gear shaft, described gear shaft is provided with the check plate that stops dual output speed change gear generation axial float.
For further strengthening the effect that stops dual output speed change gear that axial float occurs on gear shaft, described stop sleeve is provided with pressuring plate.
For making not interfere the rotation of dual output speed change gear on gear shaft, described check plate and stop sleeve all withstand on the interior ring of bearing.
Because the utility model has adopted technique scheme, two needle bearing and two clamping stopper bearings with outer ring are not only saved, also reduce the machining accuracy demand of gear shaft end, also reduced simultaneously rotatable parts quality, reduced the friction area between bearing and gear shaft, thereby played the effect that reduces oil consumption.
Brief description of the drawings
Fig. 1 is the structural drawing of the efficient speed change gear of automobile two-stage in prior art.
Fig. 2 is the structural representation of the efficient speed change gear of the utility model automobile two-stage.
Embodiment
Below in conjunction with specific embodiment, the utility model is further described, is used for explaining the utility model in illustrative examples and the explanation of this model utility, but not as to restriction of the present utility model.
As shown in Figure 1, the automobile of prior art is made up of gear shaft 1, gear box casing 2, needle bearing 3 and clamping stopper bearing 4 with outer ring with the efficient speed change gear of two-stage, gear shaft 1 is provided with dual output speed change gear 5, gear shaft 1 drives dual output speed change gear 5 to rotate with respect to gear box casing 2, between gear shaft 1 and gear box casing 2, adopt the needle bearing 3 with outer ring to carry out radial location, adopt clamping stopper bearing 4 to carry out axially locating.Its complex structure, cost are high, the having relatively high expectations of the endoporus to gear box casing 2 and gear shaft 1 machining accuracy, and also needle bearing 3 handling with outer ring are complicated, to reprocess difficulty large; And whole gear shaft 1 and himself subsidiary dual output speed change gear 5 together rotate, and friction area between each bearing is also large, and the energy needing is larger, is also unfavorable for reducing the oil consumption of automobile.
As shown in Figure 2, automobile of the present utility model comprises gear shaft 1, gear box casing 2 and dual output speed change gear 5 with the efficient speed change gear of two-stage, dual output speed change gear 5 is sleeved on gear shaft 1, between dual output speed change gear 5 and gear shaft 1, needle bearing 8 is installed.Gear shaft 1 is sleeved in gear box casing 2, part cover on gear shaft 1 between dual output speed change gear 5 and gear box casing 2 has stop sleeve 6 and packing ring 9, for further strengthening the effect that stops dual output speed change gear 5 that axial float occurs on gear shaft 1, the position that described stop sleeve 6 contacts with packing ring 9 is provided with pressuring plate 61, described dual output speed change gear 5 is the gears that two diameters do not wait, and two gears are coaxial and be processed as one.
For dual output speed change gear 5 is rotated with respect to gear box casing 2, gear box casing 2 is inserted respectively at the two ends of described gear shaft 1, and gear shaft 1 at least one end and gear box casing 2 are riveted.The convenience of dismounting while maintenance for convenience of described dual output speed change gear 5, the riveted joint between described gear shaft 1 and gear box casing 2 adopts bolt 5 to be connected, and this bolt also can replace with screw.
