Description

Oil water pump driving mechanism in the motor
Technical field
The utility model relates to the transmission device of oil pump, water pump in a kind of motor, is specifically related to oil water pump driving mechanism in a kind of motor.
Background technique
Motor is a kind of power take-off, is mainly used in traveling gears such as automobile, ship, ship.Oil pump in the motor and water pump all are the power that bent axle provides by gear transmission, the oil water pump driving mechanism comprises bent axle, driving gear, intermediate gear and driven gear composition in the existing motor, driving gear is installed on the bent axle, driven gear is installed on the input shaft of oil pump and water pump, owing to be subjected to spatial constraints, driving gear, intermediate gear and driven gear generally are arranged in the gear chamber, and are space distribution, complex structure, the processing cost height.
Summary of the invention
In order to overcome oil water pump driving mechanism complex structure in the existing motor, the deficiency that processing cost is high, the utility model provides oil water pump driving mechanism in a kind of motor, the oil water pump driving mechanism is arranged on the input shaft of oil water pump in the axis hole of trunnion shaft end in this motor, simplify the structure, save the space, reduced processing cost.
The technical solution of the utility model is: the oil water pump driving mechanism comprises bent axle and trunnion shaft in this motor, pass through the balance gear transferring power of pair of meshing between bent axle and the trunnion shaft, driving gear is installed on the bent axle, trunnion shaft is a hollow shaft, be provided with gear shaft in the axis hole of one end of trunnion shaft, driven gear is installed on the gear shaft, and driving gear is meshed with driven gear; Gear shaft links to each other with working spindle, and oil pump and water pump are installed on the working spindle successively.
The other end of described trunnion shaft is provided with dump pump.
Described driving gear is enclosed within on the wheel hub of the balance gear on the bent axle and by screw, driven gear is a nylon gear, casts on the gear shaft.
Be provided with bearing shell between described gear shaft and the trunnion shaft.
The end face of described gear shaft is provided with square counterbore, and working spindle is provided with the square spigot that cooperates with square counterbore, and working spindle and gear shaft concentric are pegged graft.
The beneficial effects of the utility model are: owing to take such scheme, oil pump and water pump adopt coaxial setting, use the support of trunnion shaft as gear shaft cleverly simultaneously, have simplified mechanism, have saved the space, have also reduced cost.
Description of drawings
Accompanying drawing 1 is a structure sectional view of the present utility model.
1-bent axle among the figure, 2-trunnion shaft, 3-balance gear, 4-driving gear, 5-gear shaft, 6-driven gear, 7-oil pump, 8-water pump, 9-working spindle, 10-dump pump, 11-bearing shell.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
By shown in Figure 1, the oil water pump driving mechanism comprises bent axle 1 and trunnion shaft 2 in this motor, pass through balance gear 3 transferring power of pair of meshing between bent axle 1 and the trunnion shaft 2, driving gear 4 is installed on the bent axle 1, trunnion shaft 2 is a hollow shaft, be provided with gear shaft 5 in the axis hole of one end of trunnion shaft 2, driven gear 6 is installed on the gear shaft 5, driving gear 4 is meshed with driven gear 6; Gear shaft 5 links to each other with working spindle 9, and oil pump 7 and water pump 8 are installed on the working spindle 9 successively.In the utility model, oil pump 7 and water pump 8 adopt coaxial setting, use the support of trunnion shaft 2 as gear shaft 5 cleverly simultaneously, have simplified mechanism, have saved the space, have also reduced cost.When selecting oil pump 7 and water pump 8 for use, make its rotating speed identical or close as far as possible.
By shown in Figure 1, the other end of described trunnion shaft 2 is provided with dump pump 10.When engine application is on the bigger equipment of ship, ship or gradient, because motor is not to be positioned at horizontal position, the lubricant oil of each lubricant housings can not in time flow back in the oil sump, oil sump tilts, lubricant oil is amesiality, the phenomenon that easily causes oil pump 7 to inhale less than lubricant oil can be forced oil return by dump pump 10, avoids lubricant oil deficiency in the oil sump.
By shown in Figure 1, described driving gear 4 is enclosed within on the wheel hub of the balance gear 3 on the bent axle 1 and by screw, driven gear 6 is a nylon gear, casts on the tooth axle 5.Can change driving gear 4 and driven gear 6 for oil pump 7 and water pump 8 that different rotating speeds requires, adjust velocity ratio, change the rotating speed of working spindle 9.
By shown in Figure 1, be provided with bearing shell 11 between described gear shaft 5 and the trunnion shaft 2.Gear shaft 5 can grind with bearing shell 11 when assembling, obtains comparatively ideal matching gap.Bearing shell 11 also can adopt bearing.
By shown in Figure 1, the end face of described gear shaft 5 is provided with square counterbore, and working spindle 9 is provided with the square spigot that cooperates with square counterbore, and working spindle 9 is pegged graft with gear shaft 5 concentrics.Oil pump 7 and water pump 8 convenience are installed.
