Abstract
The utility model provides an engine main and auxiliary shaft combining mechanism which mainly is composed of a main shaft 1, an auxiliary shaft 2, a first gear driving gear wheel 3, a first gear driven gear 4, a gear wheel 5, a spline gear 6, a gearshift sliding block 7, etc. The main shaft 1 is provided with the first gear driving gear wheel 3; the auxiliary shaft 2 is provided with the first gear driven gear 4 and the gear wheel 5; the spline gear 6 is arranged between the gear wheel 5 and the first gear driven gear 4. The engine main and auxiliary shaft combining mechanism is characterized in that the position on the main shaft 1 corresponding to the gear wheel 5 is provided with the gearshift sliding block 7 which is sheathed on the main shaft 1 through the spline and the spline groove. The engine main and auxiliary shaft combining mechanism matched with the carrier gear makes the engine obtain the built-in reverse gear function. Meanwhile, the intensity of gears of the reverse gear mechanism and more reasonable transmission ratio of each gear can be guaranteed.
Description
One, technical field:
The utility model relates to engine components, especially a kind of motor major-minor axle combined mechanism.
Two, background technique:
At present, in motor, the major-minor axle generally is designed to the coupling gear composite structure, but in order to realize the built-in of reverse gear mechanism, and guarantees easy for installation and save cost, someone changes two retainings of motor into reverse gear by a carrier gear, reverse driving gear 8, reverse gear driven gear 9 and carrier gear 10 be (as shown in Figure 2) at grade, because the structural limitations of motor own, the thickness of reverse gear is thinner than originally usually, so its intensity difference, reverse gear ratio is little.In addition, it lacks the second gear velocity ratio, and the second gear velocity ratio in use is shelves often will using, and therefore this major-minor axle composite structure is not accepted by users.
Three, summary of the invention:
The purpose of this utility model provides a kind of motor major-minor axle combined mechanism, the motor that solves the combination of traditional major-minor axle when increasing built-in reverse gear function, the reverse gear mechanism intensity difference, velocity ratio is little, and lacks the problem of second gear velocity ratio.
The technical solution of the utility model is: it comprises main shaft and countershaft, one grade of driving gear is arranged on the main shaft, first speed driven gear and gear are arranged on the countershaft, between gear and first speed driven gear, spline gear is installed, its structure characteristic is: the position of answering with gear mesh on main shaft is provided with the shift slide block, and this shift slide block is sleeved on the main shaft by spline and spline.
One grade of driving gear in the utility model on the main shaft also is a reverse driving gear simultaneously, and first speed driven gear on the countershaft and the engagement of gap bridge tooth make it to have simultaneously the effect of reverse gear carrier gear.The position of shift slide block promptly is the position of former fourth gear driving gear, the shift slide block can be connected with transmitting torque with third speed drive gear or five grades of driving gears in the front and back slip, though lacked the fourth speed velocity ratio, but because it is the gear that is of little use, therefore to using not influence, each grade velocity ratio is more reasonable.Reverse driving gear, reverse gear driven gear and carrier gear need not change the thickness of reverse gear mechanism gear not at grade, have guaranteed the intensity of reverse gear mechanism.
The utility model has the advantages that: be equipped with the gap bridge tooth and make motor have built-in reverse gear function, guaranteed the strength of gear teeth of reverse gear mechanism and more rational each grade velocity ratio simultaneously.
Four, description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is traditional reverse gear mechanism major-minor axle combined mechanism schematic representation when built-in.
Five, embodiment:
As shown in Figure 1: the utility model is made of main shaft 1, countershaft 2, one grade of driving gear 3, first speed driven gear 4, gear 5, spline gear 6 and shift slide block 7 etc., one grade of driving gear 3 is arranged on the main shaft 1, first speed driven gear 4 and gear 5 are arranged on the countershaft 2, between gear 5 and first speed driven gear 4, spline gear 6 is installed, its structure characteristic is: position corresponding with gear 5 on main shaft 1 is provided with shift slide block 7, and this shift slide block 7 is sleeved on the main shaft 1 by spline and spline.
Described shift slide block 7 and gear 5 are gapped between radially, do not contact with gear 5 to guarantee shift slide block 7.
Working principle: when motor one grade of when work, one grade of driving gear 3 on the engine spindle 1 and 4 engagements of the first speed driven gear on the countershaft 2, first speed driven gear 4 is by spline gear 6 transmitting torques, with near the gap bridge tooth (operated by rotary motion is starting shaft) and the then idle running of gear 5 of first speed driven gear 4 engagements, realize shelves; When the motor reverse gear is worked, one grade of driving gear 3 and first speed driven gear 4 engagements, and first speed driven gear 4, gap bridge tooth all dally, they all play the gap bridge effect with on the gear 5 of transmission of power to the countershaft 2, gear 5 is then by spline gear 6 transmitting torques, thus the realization reverse gear.
