Abstract
The utility model discloses a two bearing arrangement for truck fan, including fan axle and end cover, its characterized in that fan axle is fixed on the end cover through the deep groove ball bearing and the cylindrical roller bearing that set up side by side. The utility model discloses a conventional deep groove ball bearing combination of cylindrical roller bearing side by side, under the effect through external force -feed lubrication oil, the bearing capacity of improvement bearing to the rotational speed that makes the fan improves several times. The utility model discloses an unilateral couple of bearing design has overcome the restricted difficulty of rotational speed, makes the fan rotational speed higher, and the life -span is longer.
Description
Technical field
The utility model relates to the technical field of the bearing of the truck blower fan of High Rotation Speed, specifically a kind of dual bearing structure of the truck blower fan for High Rotation Speed.
Background technique
At present, the structure for truck blower fan all adopts monolateral single bearing structure, and blower fan is in running, due to the restriction of the service condition of bearing, so cause the running speed of pump restricted, as adopt too high rotating speed then bearing will soon lose efficacy, thus cause the inefficacy of truck blower fan.And in order to meet the requirement of rotating speed, guarantee blower fan long-term work, the volume of blower fan is then very huge.
Model utility content
The purpose of this utility model is to provide a kind of dual bearing structure for truck blower fan, improves the bearing capacity of bearing, thus makes the rotating speed of blower fan improve several times.
To achieve these goals, the technical solution of the utility model is as follows: a kind of dual bearing structure for truck blower fan, comprise fan shaft and end cap, it is characterized in that the deep groove ball bearing that fan shaft passes through to be arranged side by side and roller bearing are fixed on end cap, an axle sleeve is arranged with outside described fan shaft, roller bearing is arranged near the exterior edge face of axle sleeve, deep groove ball bearing is then near roller bearing arranged outside, the inner ring of deep groove ball bearing and roller bearing is fixed on fan shaft, the outer ring of deep groove ball bearing and roller bearing is then fixed on end cap inwall.
According to preferred embodiment of the present utility model, end cap is positioned at place inside roller bearing and is provided with oil inlet hole.
According to preferred embodiment of the present utility model, end cap arranges bearing mounting hole, deep groove ball bearing and roller bearing are arranged in this bearing mounting hole, and on this mounting hole, corresponding deep groove ball bearing position is milled with two grooves.
The utility model, by the combination of conventional deep groove ball bearing roller bearing side by side, under the effect by extraneous pressure lubrication oil, improves the bearing capacity of bearing, thus makes the rotating speed of blower fan improve several times.Guarantee the long-term work of truck blower fan.By current conventional rotating speed 2000RPM, can 6000RPM be increased to, like this for truck blower fan when equal rate of air sucked in required, adopt this structure that the volume of blower fan then can be made greatly to reduce.Due to the installation of the storage tank of current truck, cause the restriction of assembling position, after this structure of employing, truck blower fan can be suspended on the below of storage tank and save bodywork surface and amass, and makes the total length of truck reduce about one meter to the greatest extent like this.The utility model adopts monolateral duplex bearing to design, and overcome the restricted difficulty of rotating speed, make rotation speed of fan higher, the life-span is longer.
Accompanying drawing explanation
Fig. 1 holds project organization mounting point structural representation for this novel biaxial.
Embodiment
Below in conjunction with accompanying drawing 1 and embodiment, the utility model will be further described.
Figure comprises:
1-fan shaft,

For a dual bearing structure for truck blower fan, comprise fan shaft 1 and end cap 2, it is characterized in that fan shaft 1 is fixed on end cap 2 by the deep groove ball bearing 3 that is arranged side by side and roller bearing 4.As shown in the figure, be arranged with an axle sleeve 5 outside described fan shaft 1, axle sleeve 5 is outside equipped with sealing configuration, and described sealing mechanism comprises inner sleeve 6 and overcoat 7, and effect is used to the oil of seal lubrication bearing, prevents oil from leaking out.Roller bearing 4 is arranged near the exterior edge face of axle sleeve, deep groove ball bearing 3 is near roller bearing 4 arranged outside, the inner ring of deep groove ball bearing 3 and roller bearing 4 is fixed on fan shaft 1, the outer ring of deep groove ball bearing 3 and roller bearing 4 is then fixed on end cap 2 inwall, the head of fan shaft 1 stretches out outside deep groove ball bearing 3, and the head of fan shaft 1 is fastened with nut 8 and packing ring, the inner ring that described packing ring is close to deep groove ball bearing 3 is arranged, the inner ring of deep groove ball bearing 3 and roller bearing 4 is fixed on fan shaft 1, a fixed block 10 is then provided with outside the outer ring of deep groove ball bearing 3 and end cap, this fixed block 10 is connected with end cap by bolt, this fixed block is utilized to be fixed on end cap the outer ring of deep groove ball bearing 3.End cap 2 is positioned at place inside roller bearing 4 and is provided with oil inlet hole 9, lubricant oil enters into Bearing inner by oil inlet hole 9 and lubricates.In the utility model, deep groove ball bearing is arranged on outside, object is that roller bearing can bear larger radial force, and deep groove ball bearing can play accurate positioning action, and outside adopts deep groove ball bearing to also have an effect to be fixed cylinder roller bearing.End cap arranges bearing mounting hole, and deep groove ball bearing and roller bearing are arranged in this bearing mounting hole, this mounting hole is installed deep groove ball bearing position and is milled with two grooves, are used for running in bearings to prevent Bearing inner from feeling suffocated.
Fan shaft 4 is when High Rotation Speed, the inner ring of duplex bearing is driven to run up, the outer ring of duplex bearing is fixed on end cap 2, in the operation process of bearing, lubricant oil is needed to lubricate, lubricant oil enters into Bearing inner by oil inlet hole 9 and lubricates, and lubricant oil carries out pressure fuel feeding by oil pump, ensures the lubrication of duplex bearing under running up.
Above content is in conjunction with concrete preferred implementation further detailed description of the utility model, can not assert that the utility model is specifically implemented to be confined to these explanations above-mentioned.For the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, some simple deduction or replace can also be made, all should be considered as belonging to protection domain of the present utility model.
