Abstract
The utility model discloses a transfer case transmission device for road paving machines, wherein the transfer case is a cast case whose one end is square and the another end is round, a flange at the round end of the case is connected with an engine via a bolt, the wall of the square end is provided with a plurality of round holes. The assembly comprises the steps of fixing the driven gear on the input shaft of a hydraulic oil pump via a baffle plate and a bolt to form an integral right unit mounted on the transfer case via a disc flange, which eliminates driven gear shaft and bearing. The transfer case is a cast case, the flange hole of the case has high position tolerance accuracy of the round holes and the bolts, to realize high installment accuracy of the transfer case, the driven gear and the drive gear have high mesh accuracy, low transmission noise, long service life and high transmission efficiency.
Description
Technical field
The utility model relates to a kind of road building machine, is specifically related to the transfer case transmission device on the sub-base grader.
Background technique
Transfer case is the core position of diesel powered transmission on the sub-base grader, and its effect is that power with diesel engine is to many hydraulic-pressure pumps transmission power.The kind of drive of traditional transfer case has the following disadvantages:
1, on the transfer casing, complex structure is to the morpheme difference requirement height of transfer casing, manufacture cost height by gear shaft, Bearing Installation for driven gear.
Hydraulic-pressure pump, driven gear, gear shaft, bearing are the single-piece individual components when 2, assembling, assembling difficulty, inconvenient maintenance, overproof a little just can cause driven gear and driving gear the engagement bad, gear transmission noises is big, the gear irregular wear, reduce working life, influence transmission efficiency.
Summary of the invention
The utility model provides a kind of sub-base grader transfer case transmission device, and its transfer casing is the casting box of end Fang Yiduan circle, and the flange of casing nose circle is connected with engine body by bolt, makes many circular holes on the square end end wall.Driven gear by baffle plate, be bolted on the input shaft of hydraulic-pressure pump, make driven gear and hydraulic-pressure pump form an integral rigidity assembly, be installed on the transfer casing by flange plate again, omitted driven gear shaft and bearing.
The utility model is achieved by the following technical solution: a kind of sub-base grader transfer case transmission device, the driving gear that comprises the transfer casing, is connected with motor by shaft joint, many driven gears that are meshed with driving gear, many hydraulic-pressure pumps that are connected with driven gear; It is characterized in that: described transfer casing is the casting box of end Fang Yiduan circle, and the flange of casing nose circle is connected with engine body by bolt, makes many circular holes on the square end end wall; Many flange plate are installed on the exterior edge face at circular hole place of described transfer casing by bolt respectively; Described many hydraulic-pressure pumps are installed in respectively on the described flange plate by bolt, and the input shaft of hydraulic-pressure pump is inserted in the circular hole of described transfer casing; The end of described input shaft is connected with described driven gear by baffle plate, bolt; Described many driven gears are meshed with described driving gear respectively.
Good effect of the present utility model is:
1, simple in structure, omitted driven gear shaft and bearing, low cost of manufacture.
2, installation and maintenance are convenient, the installation efficiency height, and the engagement of driven gear and driving gear is effective, and rotational noise is low, prolongs the working life of gear, improves powerdriven efficient.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is done and to be described in further detail.
Accompanying drawing is the utility model structural representation;
Among the figure: 1, transfer casing, 2, driving gear, 3, baffle plate, 4, driven gear, 5, flange plate, 6, hydraulic-pressure pump, 7, shaft joint.
Embodiment
As shown in drawings: a kind of sub-base grader transfer case transmission device, the driving gear 2 that comprises transfer casing 1, is connected with motor by shaft joint 7, many driven gears 4 that are meshed with driving gear 2, many hydraulic-pressure pumps 6 that are connected with driven gear 4; It is characterized in that: described transfer casing 1 is the casting box of end Fang Yiduan circle, and the flange of casing nose circle is connected with engine body by bolt, makes many circular holes on the square end end wall; Many flange plate 5 are installed on the exterior edge face at circular hole place of described transfer casing 1 by bolt respectively; Described many hydraulic-pressure pumps 6 are installed in respectively on the described flange plate 5 by bolt, and the input shaft of hydraulic-pressure pump 6 is inserted in the circular hole of described transfer casing 1; The end of described input shaft is connected with described driven gear 4 by baffle plate 3, bolt; Described many driven gears 4 are meshed with described driving gear 2 respectively.
As shown in drawings: transfer case is connected and fixed the flange of transfer casing (1) nose circle when mounted by bolt and engine body.Driven gear 4 is installed in the input shaft end of hydraulic-pressure pump 6 by baffle plate 3 and bolt, make driven gear 4 and hydraulic-pressure pump 6 form an integral rigidity assembly, again many hydraulic-pressure pumps 6 are installed on the transfer casing 1 by flange plate 5 and bolt respectively, omit driven gear shaft and bearing, reduced manufacture cost.Because transfer casing 1 is casting box, the positioning tolerance precision height of the flange hole on the casing, circular hole, screw, thus make the installation precision height of transfer case, the accuracy of mesh height of driven gear 6 and driving gear 2, rotational noise is little, long service life, transmission efficiency height.
