The model utility content
Problem to be solved in the utility model provides a kind of engine cooling water pump, its objective is that to make it simple in structure, compact, weight reduction.
To achieve these goals, the technological scheme that the utility model is taked is: this engine cooling water pump that is provided, be located in the accessory wheel system of motor, comprise water pump and water pump spindle, the belt wheel seat, water pump vane is installed on the water pump spindle, the drivign belt of accessory wheel system is on the belt wheel seat, the belt wheel seat is installed on the mounting bracket, described mounting bracket is fixed on the motor, described belt wheel seat forms wheel rim by sheet metal stretching, spoke and wheel hub, the axis part of its wheel hub stretches out the cylindrical protrusion of a segment distance to the direction of mounting bracket, and this cylindrical protrusion passes mounting bracket, forms described water pump spindle.
The technological scheme of the mounting structure of the belt wheel seat in the utility model is:
Described belt wheel seat and described mounting bracket Placement are: mounting bracket has a columnar projection to the one side that the belt wheel seat is installed, and between the internal circular surfaces of the wheel hub of the outer round surface of this columnar projection and belt wheel seat, connects by bearing.
Described bearing is the biserial rolling ball bearing.
The technological scheme that prevents that water pump from leaking of the present utility model is:
Establish the water pump seal assembly between described water pump and the mounting bracket.
On the water pump spindle described in the utility model water pump vane is installed, the technological scheme of annexation between the two is: the hole of water pump vane, with water pump spindle be interference fit.
Adopt technique scheme, make to the utlity model has following advantage: water pump simple in structure; The manufacturing tolerances of water pump reduces; The maintain and replace water pump is convenient; Save the bulk of motor.
Description of drawings
Below expressed content of each width of cloth accompanying drawing of this specification and the mark among the figure are made brief description:
Fig. 1 is a sectional structure schematic representation of the present utility model;
Fig. 2 is a Facad structure schematic representation of the present utility model.
Be labeled as among the figure: 1, dust-proof cover, 2, rubber cushion, 3, bearing, 4, the belt wheel seat, 5, mounting bracket, 6, water pump vane, 7, the water pump seal assembly, 8, water pump, 9, water pump spindle.
Embodiment
Contrast accompanying drawing below, by description to embodiment, to effect and working principle, the manufacturing process of the mutual alignment between the shape of embodiment of the present utility model such as related each member, structure, the each several part and annexation, each several part and manipulate method etc., be described in further detail, inventive concept of the present utility model, technological scheme had more complete, accurate and deep understanding to help those skilled in the art.
The of the present utility model structure expressed as Fig. 1, Fig. 2, the utility model is a kind of engine cooling water pump, be located in the accessory wheel system of motor, comprise water pump 8 and water pump spindle 9, belt wheel seat 4, water pump vane 6 is installed on the water pump spindle 9, the drivign belt of accessory wheel system utilizes the motion of engine crankshaft on belt wheel seat 4, drive the motion of generator, fan, oil pump and water pump.Belt wheel seat 4 is installed on the mounting bracket 5, and described mounting bracket 5 is fixed on the motor.The hub positions of belt wheel seat 4 is provided with dust-proof cover 1, also has been provided with the rubber cushion 2 of antihunt action between dust-proof cover 1 and belt wheel seat 4.But general water pump pulley is two parts with axle, adds union pieces such as key, must make its complex structure, and design weight increases.
In order to realize making the engine cooling water pump also purpose of weight reduction simple in structure, compact, the technological scheme that the utility model is taked is: as shown in Figure 1, this engine cooling water pump that is provided, described belt wheel seat 4 forms wheel rim, spoke and wheel hub by sheet metal stretching, the axis part of its wheel hub stretches out the cylindrical protrusion of a segment distance to the direction of mounting bracket 5, this cylindrical protrusion passes mounting bracket 5, forms described water pump spindle 9.This engine cooling water pump provided by the utility model, it has and above-mentioned water pump pulley seat 4 and water pump spindle 9 is created the characteristics of one, satisfies the bulk requirement that engine wheel system is arranged.
Belt wheel seat 4 manufactures one with water pump spindle 9, and the motion of belt wheel seat 4 is directly delivered on the water pump vane 6.Adopt technique scheme, make the simple in structure of water pump 8; The manufacturing tolerances of water pump 8 reduces; Maintain and replace water pump 8 convenience; Save the bulk of motor.
In the utility model, described belt wheel seat 4 with described mounting bracket 5 Placements is: mounting bracket 5 is to the one side that belt wheel seat 4 is installed, a columnar projection is arranged, between the internal circular surfaces of the wheel hub of the outer round surface of this columnar projection and belt wheel seat 4, connect by bearing 3.Adopt this scheme to make the installation of belt wheel seat 4 reliable, surface friction drag is little.
