Abstract
The utility model relates to a water pump for motor vehicles, which is composed of a shaft jointing bearing assembly, a connecting flange, a water pump strap wheel, a water pump casing, a cover plate, a water pump impeller, and a waterseal. The utility model is characterized in that the shaft jointing bearing assembly is composed of a shaft, an outer ring, ball bearings, a ball retainer, a roller post, a post retainer, and a sealing ring; the assembly of the shaft jointing bearings adopts a structure with front rollers and rear balls; the ball end of the shaft and the outer ring adopts a peach-shaped rollaway nest four-point contact type structure. The utility model has the advantages of advanced structure, high load capability, and low failure rates.
Description
The utility model is a kind of auto pump.
At present, the used water pump of automobile is to adopt two common oiling radial ball bearings, the pommel contacts with 2 of circular raceways, load-carrying capacity is low, and end float misalignment is big, easily causes bearing failure and water seal to leak, be the standard transition fit between bearing and water pump spiral case, structure tolerance easily causes between bearing and the spiral case pine spacious or bearing end-play is too small under ultimate limit state, and bearing is easily ablated, the fault rate height.
The purpose of this utility model provides a kind of auto pump of new structure, and its load-carrying capacity is big, and fault rate drops to below the millesimal.
The utility model auto pump, it is by the shaft connecting bearing assembly, butt flange, water pump pulley, the water pump shell, cover plate, water pump vane, water seal is formed, spherical structure behind the roller before wherein shaft connecting bearing adopts, the assembling process of shaft connecting bearing is, with ball pack into the outer ring and the axle peach shape raceway in, put into the ball retainer, ball is located, roller is put into the post retainer, be installed in the styletable of outer ring and axle, then left and right sides seal ring pressed, finish the assembly of shaft connecting bearing and install, the shaft connecting bearing assembly is pressed into the water pump shell, water seal is cooperated with axial compression, and water pump vane cooperates with axial compression, and butt flange cooperates with axial compression then, cover plate is fixed by bolts on the water pump shell, water pump pulley is fixed by bolts on the butt flange.
The shaft connecting bearing assembly is made up of axle, outer ring, ball, ball retainer, roller, post retainer, seal ring, roller, back spherical structure before the assembly of its shaft connecting bearing adopts, adopt the structure of 4 contacts of peach shape raceway in the pommel of axle and outer ring, be that ball contacts with 4 of the peach shape raceways of outer ring at axle, the radius of adjacent two arcs of peach shape raceway in the pommel of axle becomes 15 °～30 ° angles with line of centers, the radius of adjacent two arcs of pommel peach shape raceway of inboard, outer ring becomes 15 °～30 ° angles with line of centers.
The utility model structure advanced person, load-carrying capacity is strong, and fault rate is low.
Below in conjunction with accompanying drawing the utility model is done detailed description.
Fig. 1 is a water pump complement.
Fig. 2 is the shaft connecting bearing assembly.
Fig. 3 is four spot contact bearing partial enlarged drawings.
The utility model auto pump, it is by shaft connecting bearing assembly 14, butt flange 13, water pump pulley 12, water pump shell 11, cover plate 10, water pump vane 9, water seal 8 is formed, outer ring 2 and axle 1 are sleeved on together, ball 3 is packed in the peach shape raceway in outer ring 2 and axle 1 pommel, put into ball retainer 4, with ball 3 location, roller 5 is put into post retainer 6, be installed in the styletable of outer ring 2 and axle 1, then left and right sides seal ring 7 is pressed, finish the assembly of shaft connecting bearing and install, shaft connecting bearing assembly 14 is non-standard interference fit with water pump shell 11, with water seal 8 and axle 1 force fit, water pump vane 9 and axle 1 force fit, with butt flange 13 and axle 1 force fit, cover plate 10 usefulness bolts 15 are fixed on the water pump shell 11, and water pump pulley 12 usefulness bolts 16 are fixed on the butt flange 13 then.
Shaft connecting bearing assembly 14 is made up of axle 1, outer ring 2, ball 3, ball retainer 4, roller 5, post retainer 6, seal ring 7, roller, back spherical structure before the assembly of its shaft connecting bearing adopts, adopt the structure of 4 contacts of peach shape raceway in the pommel of axle 1 and outer ring 2, be that ball 3 contacts with 4 of the peach shape raceways of outer ring 2 at axle 1, the radius of adjacent two arcs of peach shape raceway of axle 1 and line of centers form 25 ° of angles, and the radius of adjacent two arcs of outer ring 2 peach shape raceways and line of centers form 25 ° of angles.
