Abstract
The invention relates to a cooling water pump transmission device for an engine. The cooling water pump transmission device comprises a water pump body (8) which is arranged on a transmission case of an engine, a water pump shaft (2), a gear cover (4) and a near impeller bearing (7) are arranged on the water pump body (8), a far impeller bearing (3) is arranged on the gear cover (4), a transmission gear (5) and a spacer sleeve (6) are arranged between the far impeller bearing (3) and the near impeller bearing (7), the far impeller bearing (3) is connected with the transmission gear (5) and the spacer sleeve (6) by a first screw nut, the near impeller bearing (7) is connected with the transmission gear (5) and the spacer sleeve (6) by a second screw nut (9), and the transmission gear (5) is arranged on the water pump shaft (2) and connected with the water pump shaft through a spline. The device has a compact structure, the occupied space of the water pump can be narrowed, the integral disassembly and assembly of the water pump can be realized, component acceptance and water pump maintenance are very convenient, and the service life of the bearings can be prolonged.
Description
Technical field
The invention belongs to parts of motor, be specifically related to a kind of engine cooling water pump transmission device.
Background technique
In engine-cooling system, cooling water is driven by water pump, flows through the heating part and the heat absorptions such as machine oil cooler, intercooler, body, cylinder cap of motor, and temperature raises; Inflow radiator discharges the heat that is absorbed again, and temperature drops to the level before the heat absorption, gets back to the water pump import then.So go round and begin again, form the water cycle of cooling system.Water pump is the vitals of this system, and cooling water can be circulated with certain pressure and flow.Water pump generally drives belt pulley or gear drive by motor.For gear transmission, general driving gear stretches in the transmission case outside water pump, makes the size of the outstanding motor of water pump bigger, and for the large and medium-sized motor that compactedness is had relatively high expectations, this problem is particularly outstanding.
Summary of the invention
Technical problem to be solved by this invention is to overcome above-mentioned deficiency, a kind of engine cooling water pump transmission device is provided, and this device has reduced the size that water pump stretches out transmission case, improves the complete machine compactedness, can realize the integral disassembly, assembly of water pump, make things convenient for parts to check and accept and the water pump maintenance.
Technological scheme of the present invention: a kind of engine cooling water pump transmission device, it comprises first nut, water pump spindle, impeller bearing far away, gear cover, driving gear, spacer sleeve, nearly impeller bearing, water pump body, second nut and transmission idle pulley, water pump body is arranged on the motor transmission case, water pump spindle, gear cover, nearly impeller bearing is arranged on the water pump body, impeller bearing far away is arranged on the gear cover, driving gear, spacer sleeve is arranged between impeller bearing far away and the nearly impeller bearing, impeller bearing far away is by first nut and driving gear, spacer sleeve connects, nearly impeller bearing is by second nut and driving gear, spacer sleeve connects, driving gear is arranged on the water pump spindle, connects by spline.Window and the transmission idle pulley engagement of driving gear by offering on the gear cover.
The present invention compared with prior art has following beneficial effect: utilize the space between two bearings of water pump in the conventional construction, driving gear is placed wherein, transmission window and the driving wheel engagement of gear by offering on the gear cover.Make the water pump spindle bearing outside transmission case partly put into transmission case, reduce the size that water pump stretches out transmission case greatly, improve the complete machine compactedness; Impeller bearing far away supports by gear cover, can realize the integral disassembly, assembly of water pump, makes things convenient for parts to check and accept and the water pump maintenance; Because gear between two bearings, is compared the conventional boom-mounted gear structure, has reduced the load of bearing greatly, has prolonged bearing life; Because the transmission case gear generally adopts splash lubrication, adopts the bearing lubrication condition of this structure to be greatly improved, and does not need to design special lubricating structure again.
