Abstract
The utility model discloses a reduction gearbox used for an electric forklift truck. The reduction gearbox comprises a box body, an input gear is arranged in the box body and connected with a duplex gear, the duplex gear is connected with a driving gear on a middle gear shaft, a driven gear is also arranged on the middle gear shaft and connected with an external differential assembly, the box body is 'L'-shaped, and the middle gear shaft and the input gear are respectively arranged at two edges of the 'L'-shaped box body. As the box body of the reduction gearbox is L-shaped, motor input and differential output are parallel to one edge of the 'L'-shaped box body, the middle gear shaft connected with the differential is staggered with a transmission gear connected with a motor, namely the motor can be arranged in a space formed by staggering the middle shaft and the transmission gear rather than in linear arrangement with the transmission gear originally, and the length of a speed reducer is shortened so as to achieve more convenient installation.
Description
Technical field
The utility model relates to a kind of speed reducer, particularly a kind of speed reducer that is used for Electric Fork Lift Trucks.
Background technique
Present fork truck be mostly with internal-combustion engine as power, but the waste gas of internal-combustion engine and noise pollution are serious, so the fork truck that is used as power with motor more and more obtains everybody favor.Speed reducer and the structure of using on the Electric Fork Lift Trucks on the internal-combustion engine is similar now, all is from prime mover input power, by the series of gears transmission, at last power is passed on the differential mechanism then.But the formula structure of arranging that present speed reducer all is the straight line one, promptly from motor, the whole driving gear and the differential mechanism of back all are that same in order linear array is come, and the volume of whole like this speed reducer is just bigger, and it is not too convenient to be installed on the fork truck.
Summary of the invention
At the problems referred to above, the purpose of this utility model be to provide a kind of simple in structure, volume is little, saves the speed reducer that is used for Electric Fork Lift Trucks in space.
The technical solution of the utility model: a kind of speed reducer that is used for Electric Fork Lift Trucks, comprise casing, be provided with the input gear in the casing, the input gear connects duplicate gear, and duplicate gear connects the driving gear on the intermediate gear shaft, and driving gear is arranged on the intermediate gear shaft, also be provided with driven gear on the intermediate gear shaft, driven gear connects outside differential assembly, and described casing is " L " type, and intermediate gear shaft is separately positioned on the both sides of " L " molding box body with the input gear.
As preferably, described intermediate gear shaft one end is with tapered roller bearing, and the tapered roller bearing outer ring is fixed on the bearing support; Tapered roller bearing bears the suffered axial force and the radial force of intermediate gear shaft.
As preferably, described intermediate gear shaft is with adjusting nut at the end that tapered roller bearing is housed, and adjusting nut is pushed down the inner ring of tapered roller bearing; By the rotation adjusting nut, the convenient gap of adjusting the conical bearing Internal and external cycle, after being installed to inner ring on the outer ring, the gap of debugging Internal and external cycle is very convenient like this.
As preferably, a side of described casing will be imported the end encapsulation of gear, duplicate gear and intermediate gear shaft by case lid, and the opposite side of casing is by the other end encapsulation of end cap with intermediate gear shaft; Whole speed reducer is settled by casing, case lid and the encapsulation of end cap three parts, and integral installation is very convenient.
As preferably, be connected by pin between described case lid and the casing, be connected by bolt between end cap and the casing.
As preferably, described input gear by Bearing Installation on casing.
As preferably, described duplicate gear is arranged on the rotatingshaft, rotatingshaft by bearing fixing on casing.
Retarder of the present utility model is by being arranged to casing on " L " type, the motor input is output as along the one side " parallel " of " L " with differential mechanism and arranges, make the setting of staggering of intermediate gear shaft that connects differential mechanism and the driving gear that is connected motor, promptly avoided the setting of arranging of whole linear type, motor just can be changed into horizontal by original disposed upright like this, be that motor can be arranged setting by original and driving gear linear type and changes into and be arranged on the space of vacateing after intermediate gear shaft and driving gear stagger, shortened the length of retarder like this, make utilization of space more effective, the volume of whole retarder reduces greatly, and is comparatively convenient in the time of installation.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a transmission schematic representation of the present utility model.
Embodiment
As shown in Figure 1, a kind of speed reducer that is used for Electric Fork Lift Trucks, comprise casing 1, be provided with input gear 3 in the casing 1, input gear 3 connects duplicate gear 4, the driving gear 5 that duplicate gear 4 connects on the intermediate gear shaft 6, also be provided with driven gear 7 on the intermediate gear shaft 6, driven gear 7 connects outside differential assembly, and casing 1 is " L " type, and intermediate gear shaft 6 is separately positioned on the both sides of " L " molding box body with input gear 3.Intermediate gear shaft 6 one ends are with tapered roller bearing 14, and tapered roller bearing 14 outer rings are fixed on the bearing support 2.Intermediate gear shaft 6 is with adjusting nut 9 at the end that tapered roller bearing 14 is housed, and adjusting nut 9 is pushed down the inner ring of tapered roller bearing 14.Two tapered roller bearings 14 are set on intermediate gear shaft 6, in order to bear axial force and the radial force that intermediate gear shaft 6 is subjected to; Overlap an adjusting nut 9 simultaneously on intermediate gear shaft 6, tapered roller bearing is earlier the outer ring to be fixed on the bearing support, inner ring is enclosed within the inside, outer ring again, and adjusting nut 9 can be regulated the gap between the Internal and external cycle very easily; Gap between two tapered roller bearings has spacer 17 to adjust, and by adjusting nut 9 lockings, has guaranteed to have between two tapered roller bearings normal play to exist so then.The end that one side of casing 1 will be imported gear 3, duplicate gear 4 and intermediate gear shaft 6 by case lid 10 encapsulates, and the opposite side of casing 1 is by the other end encapsulation of end cap 11 with intermediate gear shaft 6.Be connected by pin 15 between case lid 10 and the casing 1, be connected by bolt 16 between end cap 11 and the casing 1.Input gear 3 is installed on the casing 1 by bearing 12.Duplicate gear 4 is arranged on the rotatingshaft 13, rotatingshaft 13 by bearing fixing on casing 1.The A place is used to install motor among Fig. 1, avoided the setting of arranging of whole linear type like this, motor just can be changed into horizontal by original disposed upright like this, be that motor can be arranged setting by original and driving gear linear type and changes into and be arranged on the space of vacateing after intermediate gear shaft and driving gear stagger, shortened the length of retarder like this, make utilization of space more effective, the volume of whole retarder reduces greatly, and is comparatively convenient in the time of installation.
As shown in Figure 2, during speed reducer work, the power of motor at first is passed to input gear 3, and motor output shaft is connected by spline between the gear 3 with input, and transmission of power is in proper order then: import gear 3 → duplicate gear 4 → driving gear 5 → driven gear 7 → differential assembly 8.
