Abstract
The utility model relates to a shaft coupled bearing of an automobile water pump, which is installed in a bearing bore of a water pump casing. An entire water sealing is installed on the middle lower part of the portion of the shaft coupled bearing and positioned in a water sealing bore of the water pump casing; a belt pulley is installed on the upper end of the shaft coupled bearing. The utility model is characterized in that a blade wheel of the water pump is positioned on the lower end surface of the water pump casing and installed on the lower end of the shaft coupled bearing; a circular bead is arranged in a bearing bore of the water pump casing; a water storing chamber is arranged outside the water pump casing; the lower end surface of the water pump casing is connected with an engine body by a positioning pin. The utility model has the advantage that the blade wheel is exposed outside and can directly connect the water pump casing with an engine, with the characteristics of simple structure, convenient connection and reliable sealing. In addition, a water pump assembly is added with the circular bead in the bearing bore of the water pump casing, therefore the axial positioning is ensured by the circular bead. At the same time, the water pump assembly is added with a water storing chamber outside the water pump casing so as to prevent the flowing trace outside the casing. The adoption of the toothed belt pulley can enhance the transmission efficiency, reduce the loading of the bearing, and ensure no losing rotation.
Description
Technical field
The utility model belongs to the pump technology field of auto manufacturing technology, particularly a kind of auto pump.
Background technique
At present, the cooling waterpump that automobile is used, especially the small pump of extensive use generally adopts shaft connecting bearing, integrated type water seal, pack alloy housing, steel plate punching press belt pulley, steel plate punching press impeller on light, car.And automobile-used cooling waterpump generally adopts whole stand alone type to arrange, connect with engine block by 2-4 place supporting surface, the major defect of this kind form be water pump structure complicated and with the inconvenience that connects of engine block, it is bad easily to produce the connection soundness, serious vibration when causing pump working, perhaps produced the location, sealing effect is bad.
Water pump shaft connecting bearings is the vital part that influences the water pump complement quality, and the reliability that connects between the operating conditions of shaft connecting bearing and shaft connecting bearing and the water pump cover also has material impact to the quality of water pump complement.The connecting mode that generally adopts is to realize by the interference fit between shaft connecting bearing outer ring and water pump cover bearing hole at present.Because water pump cover (material is a pack alloy) is different with the material of shaft connecting bearing outer ring (material is a steel), thermal expansion coefficient is also different, and the pump working temperature is through being everlasting in 80-100 ℃, at this moment the magnitude of interference between shaft connecting bearing outer ring and water pump cover bearing hole will be much smaller than the magnitude of interference under the normal temperature state, the friction of guaranteeing positive connection between shaft connecting bearing outer ring and water pump cover bearing hole also will significantly reduce, shaft connecting bearing is (impeller direction) play easily forward, will cause water seal to be leaked.If increase the magnitude of interference that cooperates between shaft connecting bearing outer ring and water pump cover bearing hole, will make the shaft connecting bearing radial internal clearance too small, can cause the bearing ablation again.
The indoor water of present water pump bearing zone volume is too small, easily produces the washmarking mark in outside, and the water pump that the user will be under the normal working thinks it is the pump that leaks by mistake.
In addition, the present stage power input of most water pumps is imported into by " V " shape belt pulley or expansion tightening wheel form, easily cause throwing switch or the shaft connecting bearing load excessive.
Summary of the invention
The purpose of this utility model is the defective of finding in actual applications at above-mentioned vehicle water pump structural type, has done corresponding improvement at aspects such as water pump cover structures, and a kind of auto pump of new structure is provided.
The technical solution of the utility model is achieved in that
The utility model auto pump is made up of belt pulley, shaft connecting bearing, integrated type water seal, water pump cover, water pump vane, shaft connecting bearing is installed in the bearing hole of water pump cover, the integrated type water seal is installed in the middle and lower part of shaft connecting bearing, be positioned at the water seal hole of water pump cover, belt pulley is installed in the upper end portion of shaft connecting bearing, it is characterized by:
Described water pump vane is positioned at the lower end surface of water pump cover, is installed in the underpart of shaft connecting bearing,
One shoulder is arranged in the bearing hole of described water pump cover, and water pump cover has a water storage chamber outward, and the lower end surface of water pump cover is connected with engine body by locating stud.
The utility model auto pump, it is characterized by described belt pulley is toothed belt wheel.
The utility model auto pump is characterized by between the lower end surface of described water pump cover and the engine block gasket seal is installed, and is connected with engine body by two locating studs.
Advantage of the present utility model is to have cancelled traditional volute casing, and impeller is exposed, and directly water pump cover is connected with engine block, so that simple in structure, it is convenient to connect, and sealing is reliable.Water pump complement has increased a shoulder in the water pump cover bearing hole in addition, like this magnitude of interference between shaft connecting bearing outer ring and water pump cover bearing hole need only guarantee shaft connecting bearing the radial internal clearance size to fit both can, and axially locating is guaranteed by shoulder.Water pump complement is set up water storage chamber outside water pump cover simultaneously, in case produced the washmarking mark in outside; Owing to adopt toothed belt wheel, can improve transmission efficiency, lower the load of bearing, and can guarantee not throw switch.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the utility model surface structure schematic representation.
Embodiment
Describe specific embodiments of the present utility model in detail below in conjunction with accompanying drawing.
The utility model is made up of belt pulley 1, shaft connecting bearing 2, integrated type water seal 3, water pump cover 4, water pump vane 5, shaft connecting bearing 2 is installed in the bearing chamber of water pump cover 4, integrated type water seal 3 is installed in the middle and lower part of shaft connecting bearing 2, be positioned at the water seal hole of water pump cover 4, it is characterized by: belt pulley 1 is installed in the upper end portion of shaft connecting bearing 2, water pump vane 5 is installed in the underpart of shaft connecting bearing 2, and the connection power between above-mentioned parts all derives from interference fit.
One shoulder is arranged in the bearing hole of water pump cover 4, during the water pump complement assembling, the outer ring of shaft connecting bearing 2 shoulder therewith is close to, magnitude of interference between the bearing hole of the outer ring of shaft connecting bearing 2 and water pump cover 4 need only guarantee that the radial internal clearance size to fit of shaft connecting bearing both can like this, and axially locating is guaranteed by shoulder, does not produce axial float between shaft connecting bearing and the water pump cover to guarantee water pump complement when the condition of high temperature is worked.Water pump cover has a water storage chamber 6 outward, in case produced the washmarking mark in outside.
The utility model is with the volute casing cancellation of existing water pump, impeller 5 is exposed, the lower end surface of water pump cover 4 (big plane) directly connects with engine block (plane), between two each planes gasket seal can be installed, determine the position of water pump complement on motor by two locating studs then, with bolt water pump complement is fixed on the motor at last.
