Abstract
The utility model discloses an inclined-shaft back cover for a plunger hydraulic pump. The inclined-shaft back cover is fixed at the back end of a shell of the plunger hydraulic pump, and is positioned on the back side of a thrust plate in the shell; the back cover is contacted with the thrust plate of the hydraulic pump; the contact surface between the back cover and the thrust plate is a concave cambered surface; and the corresponding contact surface of the thrust plate is a matched convex cambered surface. Due to the adoption of a non-fixed structure, the thrust plate can move along the back cover to change the pouring angle, so that the adjustment of the displacement is realized, and the displacement is larger when a displacement angle is larger. Moreover, the contact surfaces are cambered surfaces, so that the adjusting range of the pouring angel can be expanded, and meanwhile, the movement of the thrust plate can be adjusted more smoothly.
Description
Technical field
The utility model belongs to hydraulic pump/motor, especially relates to a kind of inclined plunger hydraulic pump bonnet.
Background technique
Inclined plunger hydraulic pump/motor, be mainly used in the hydraulic driving of running mechanism, traditional inclined plunger hydraulic pump/motor mainly comprises housing, be fixed on end cap, the bonnet of housing front end, rear end, be installed on motor spindle, mandrel, plunger part, cylinder body and the thrust plate of enclosure interior; Wherein motor spindle one end stretches out end cap, and the other end is provided with the ball-and-socket dish, and mandrel, plunger part one end are located at respectively in the ball-and-socket dish, and the mandrel and the plunger part the other end are located in the cylinder body.Adopt the hydraulic pump/motor of said structure, have plunger part processing simply, reliable transmission, advantages such as can enhancing productivity and reduce the cost.But,, thereby make existing inclined plunger hydraulic pump/motor all can't realize its discharge capacity is carried out corresponding adjusting because its thrust plate is to adopt to fixedly connected with bonnet.
The model utility content
Technical problem to be solved in the utility model provides a kind of inclined plunger hydraulic pump bonnet, can realize its discharge capacity is regulated, and can also increase the regulation range of the measuring angle that inclines.
In order to solve the problems of the technologies described above, the utility model adopts following technological scheme:
A kind of inclined plunger hydraulic pump bonnet, be fixed on the rear end of the housing of this plunger hydraulic pump, and be positioned at the rear side of the thrust plate of being located at housing, described bonnet contacts with the thrust plate of this oil hydraulic pump, and the surface of contact of bonnet and thrust plate is a concave arc surface, and the corresponding contact face of thrust plate is the convex globoidal that is complementary.
Adopt inclined plunger hydraulic pump bonnet of the present utility model, have following advantage:
1, the on-fixed structure can make thrust plate move along bonnet, changing its measuring angle that inclines, thereby realizes adjusting to discharge capacity, and the angulation of promptly inclining is big more, and discharge capacity is big more.
2, surface of contact is a cambered surface, increases the regulation range of the measuring angle that inclines, and makes that also the mobile adjusting of thrust plate is more smooth and easy simultaneously.
Description of drawings
Be elaborated below in conjunction with the drawings and specific embodiments the utility model:
Fig. 1 is the sectional arrangement drawing of inclined plunger hydraulic pump bonnet of the present utility model.
Fig. 2 is the right elevation among Fig. 1.
Embodiment
The utility model is to be example with the inclined plunger hydraulic pump, as shown in Figure 1 and Figure 2, it is fixed on the rear end of the housing 1 of inclined plunger hydraulic pump, this bonnet 3 is not fixedly connected with the thrust plate 8 of oil hydraulic pump, but contact, and bonnet 3 has inner chamber, the driving mechanism that the bottom is connected with thrust plate 8 in addition in the inner chamber, and move along bonnet 3 surface of contact by drive mechanism thrust plate 8, this driving mechanism is a hydraulic drive mechanism.Thereby can change its measuring angle that inclines, to realize the adjusting to its discharge capacity, the angulation of promptly inclining is big more, and discharge capacity is big more.
Described bonnet 3 is a concave arc surface with the surface of contact of thrust plate 8, and the corresponding contact face of thrust plate 8 is the convex globoidal that is complementary.Adopt the surface of contact of cambered surface form, thrust plate 8 moves on concave arc surface, can make bigger that its angulation scope of inclining becomes, thereby effectively increase the incline regulation range of measuring angle of this plunger hydraulic pump, cambered surface contact simultaneously makes that also the mobile adjusting of thrust plate 8 is more smooth and easy.
But, those of ordinary skill in the art will be appreciated that, above embodiment is used for illustrating the utility model, and be not to be used as qualification of the present utility model, as long as in connotation scope of the present utility model, all will drop in claims scope of the present utility model the above embodiment's variation, modification.
Claims (2)
1. an inclined plunger hydraulic pump bonnet is fixed on the rear end of the housing of this plunger hydraulic pump, and is positioned at the rear side of the thrust plate of being located at housing, it is characterized in that:
Described bonnet contacts with the thrust plate of this oil hydraulic pump, and the surface of contact of bonnet and thrust plate is concave arc surface, and the corresponding contact face of thrust plate is the convex globoidal that is complementary.
2. according to the described inclined plunger hydraulic pump bonnet of claim 1, it is characterized in that: have inner chamber in the described bonnet, be provided with the hydraulic drive mechanism that is connected with thrust plate in the described inner chamber.
