Abstract
A diesel engine hydraulic oil pump driving device comprises a hydraulic pump transition connecting block, a gear chamber, a deep groove ball bearing, a hydraulic pump driving gear, a gear chamber cover, an angular contact bearing and a hydraulic pump connecting plate. The hydraulic pump driving gear is provided with an internal spline, one end of the hydraulic pump driving gear is supported on the gear chamber through the deep groove ball bearing, the other end of the hydraulic pump driving gear is supported on the gear chamber cover through the angular contact bearing, the hydraulic pump transition connecting block is installed on the gear chamber, and the hydraulic pump connecting plate is installed on the gear chamber cover. The rolling bearings are used for supporting, so that friction loss is reduced; as the internal spline and the gear are arranged to be integrated, the number of the parts is reduced, and the specification of the internal spline can be enlarged to be matched with a hydraulic pump with larger discharge capacity. Axial force generated by the bevel gear is borne by the angular contact bearing, the other bearing is the common deep groove ball bearing, and the two bearings are supported on the gear chamber and the gear chamber cover respectively, so that the performance of the diesel engine hydraulic oil pump driving device is further improved, and reliability is also improved.
Description
Technical field
The utility model belongs to diesel engine field, relates to a kind of diesel powered ejector, relates in particular to a kind of diesel engine hydraulic oil pump driving device.
Background technique
At present, in diesel engine of the prior art, the most of sliding bearing that adopts of gear in the power ejector of its driving hydraulic-pressure pump supports, and adopts limiting board limit its axial float and bear axial force.Drive internal spline and the gear of hydraulic-pressure pump not to be provided in a side of on same part, therefore need the structure of spline joint, required part is more, complex structure not only, and difficulty of processing is large, also the easy over worn problem of generation limiting board.If use roller bearings instead, internal spline and gear are made as to one, not only can reduce frictional loss, can also simplified structure, both reduced number of spare parts, can also strengthen internal spline specification, the oil hydraulic pump of supporting larger discharge capacity.The axial force that helical gear produces is born by angular contact bearing, and another bearing is common deep groove ball bearing, and two bearings are supported on respectively on gear chamber and gear chamber cover.This mentality of designing is further improved the performance of diesel engine hydraulic oil pump driving device, and reliability also further improves.
Model utility content
The utility model object is to provide a kind of reliable operation, rational in infrastructure, with low cost, easy maintenance, arranges easily the diesel engine hydraulic oil pump driving device of complete function.
The utility model achieves the above object by the following technical solutions: diesel engine hydraulic oil pump driving device, comprising: oil hydraulic pump transition contiguous block, gear chamber, deep groove ball bearing, hydraulic pump drive gear, gear chamber cover, angle contacting axle, oil hydraulic pump joining plate; On hydraulic pump drive gear, be provided with internal spline, one end is supported in gear chamber with deep groove ball bearing, and the other end is supported on gear chamber cover with angular contact bearing, and oil hydraulic pump transition contiguous block is arranged in gear chamber, and oil hydraulic pump joining plate is arranged on gear chamber cover.
The utility model adopts the good effect reaching after technique scheme to be: use roller bearings instead, reduced frictional loss; Internal spline and gear are made as one, have reduced number of spare parts, can also strengthen the specification of internal spline, oil hydraulic pump that can supporting larger discharge capacity.The axial force that helical gear produces is born by angular contact bearing, another bearing is common deep groove ball bearing, two bearings are supported on respectively on gear chamber and gear chamber cover, and the performance of diesel engine hydraulic oil pump driving device is further improved, and reliability also further improves.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model diesel engine hydraulic oil pump driving device.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.Diesel engine hydraulic oil pump driving device, comprising: oil hydraulic pump transition contiguous block 1, gear chamber 2, deep groove ball bearing 3, hydraulic pump drive gear 4, gear chamber cover 5, angle contacting axle 6, oil hydraulic pump joining plate 7, deep groove ball bearing 3 and angular contact bearing 8 are installed respectively in hydraulic pump drive gear 4 two ends, one end that deep groove ball bearing 3 is installed is supported in gear chamber 2, established angle contact bearing 6 one end are bearing on gear chamber cover 5, the axial position of oil hydraulic pump transition contiguous block 1 restriction bearing in gear chamber, the seam that connects hydraulic-pressure pump is provided simultaneously, between oil hydraulic pump transition contiguous block 1 and gear chamber 2, by seam, locate, guarantee that two parts are concentric, oil hydraulic pump joining plate 7 limits the axial position of angular contact bearing 6 on gear chamber cover 5, utilize bearing outer ring concentric with gear chamber cover 5, and provide the seam that connects hydraulic-pressure pump, hydraulic pump drive gear 4 two ends are equipped with inner splined hole, hydraulic-pressure pump in order to drive installation to rear and front end.The axial force that hydraulic pump drive gear produces is born by angular contact bearing 6, finally by oil hydraulic pump joining plate 7, is kept out, and it should be noted that angular contact bearing 6 has installation direction, must not be anti-loaded, if anti-loaded, the ability of bearing axial force will be declined greatly.
The utility model is rational in infrastructure, reliable operation, with low cost, easy maintenance.
