Abstract
The utility model discloses a kind of new work engine transition belt pulley, comprise belt wheel body, the middle part of described belt wheel body has a plate-like host cavity, the middle part of this plate-like host cavity is axially installed with six flange face bolts, the rolling bearing being placed on described tune gap cushion block is also provided with in described plate-like host cavity, be provided with outside described rolling bearing and install bearing bearing catch, bearing catch is pressed on described rolling bearing by multiple pressure point block that is circumferentially provided with at the Yan Kou place of described plate-like host cavity.The press-fit approach that the utility model solves belt pulley of the prior art and roller bearing shop employing installs the problem unreliable, mounting process is complicated, and practical, is worthy to be popularized.
Description
Technical field
The utility model relates to a kind of new work engine transition belt pulley.
Background technique
In existing technology, transition belt pulley is made up of 5 component: transition belt pulley, dust-proof cover, bearing, tune gap cushion cover and hexagon flange bolt.Transition belt pulley adopts the mode of interference fit or hot jacket bearing and belt wheel to be press-fited usually, and this assembling mode cost is higher, and reliability is not enough; In endurance test, the working life of plain bearing can not meet car load requirement in working life.In view of above reason, so existing transition belt pulley designed reliability is not enough, in use due to the actual effect of bearing, easily causes the generation of noise, cause client to complain.
Model utility content
The utility model, in order to solve the above-mentioned deficiency of prior art, proposes a kind of new work engine transition belt pulley.
In order to solve the problems of the technologies described above, the utility model is by the following technical solutions: a kind of new work engine transition belt pulley, comprise belt wheel body, the middle part of described belt wheel body has a plate-like host cavity, the middle part of this plate-like host cavity is axially installed with six flange face bolts, is provided with the tune gap cushion block be enclosed within six flange face bolts between this six flange face bolts and belt wheel body; The rolling bearing being placed on described tune gap cushion block is also provided with in described plate-like host cavity, be provided with outside described rolling bearing and bearing bearing catch is installed, this bearing baffle is installed on six flange face bolts, and bearing catch is pressed on described rolling bearing by multiple pressure point block that is circumferentially provided with at the Yan Kou place of described plate-like host cavity; Described six flange face bolts are also provided with the dust-proof cover be placed in outside rolling bearing.
Preferably, the front side of described tune gap cushion block is also provided with O type rubber seal.
Preferably, described belt wheel body adopts V-type transition belt pulley.
Compared with prior art, the inner chamber collecting rolling bearing of belt wheel body of the present utility model, and rolling bearing and belt wheel body adopt interference fit and adopt bottom bag pressure, the pressure point block arranged adopts face points to compress into being mounted with of row bearing and belt wheel, make bearing accurate positioning, axially there is no vibration, convenient and reliable, this assembling mode operation is simple, and efficiency is high.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the partial enlarged drawing at a-a place of the present utility model.
Embodiment
Below in conjunction with drawings and Examples, model utility is described in detail.
As shown in Figure 1, 2, the new work engine transition belt pulley that the utility model proposes, comprise belt wheel body 1, belt wheel body 1 is V-type transition belt pulley, the middle part of belt wheel body has a plate-like host cavity, the middle part of this plate-like host cavity is axially installed with six flange face bolts 2, is provided with the tune gap cushion block 3 being enclosed within six flange face bolts 2 between this six flange face bolts 2 and belt wheel body 1; The rolling bearing 4 being placed on described tune gap cushion block 3 is also provided with in plate-like host cavity, be provided with outside rolling bearing 4 and bearing bearing catch 5 is installed, this bearing baffle is installed on six flange face bolts 2, and bearing catch 5 is pressed on rolling bearing by multiple pressure point block 8 that is circumferentially provided with at the Yan Kou place of plate-like host cavity; Six flange face bolts 2 are also provided with the dust-proof cover 6 be placed in outside rolling bearing.The front side of gap cushion block 3 is adjusted also to be provided with O type rubber seal 7.
In the utility model, rolling bearing model is NSK 6303 2RS, and bearing element bearing 4 and belt wheel body 1 adopt interference fit and bag pressure bottom adopting, and face points compresses into being mounted with of row bearing and belt wheel; For preventing hexagon flange bolt from dropping, increase O type rubber seal fixing bolt in bottom, this assembling mode operation is simple, and efficiency is high.
Belt wheel body 1 adopts SPHE deep-draw level hot-strip material, is made with impact style, and stamping process is simple, and cost is low, and belt pulley lighter in weight.Belt pulley is the 6PK poly Vbelt belt grooved of standard, also adaptively can be used as poly Vbelt or the V-shape belt of other models.
The point compression technology of pressure point block is at belt pulley and rolling bearing jointing edge, and at its 360 ° circumferentially uniform 4 pressure points, each pressure point is of a size of 3 × 0.5mm.
Above-described embodiment only have expressed several mode of execution of the present utility model, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the utility model patent and protection domain should be as the criterion with appended claims.
