Description
Technical Field
The utility model relates to a transmission shaft supports assembly part technical field, specifically is a transmission shaft intermediate strut assembly.
Background
The support assembly is a part of the transmission shaft assembly and is used for supporting the transmission shaft to rotate. Since elastic suspensions such as engine suspensions cause angular and linear displacements during driving, an intermediate support is required to be able to absorb the vibrations. The axial stiffness of the support assembly is linear with bearing life. The greater the stiffness, the lower the lifetime. The existing intermediate support has high axial rigidity, and in order to reduce the influence of the high axial rigidity on the service life of a bearing, the support assembly structure of the existing structure is that the bearing can axially slide in a bearing seat. The bearing and the bearing seat are in clearance fit, and the bearing can vibrate along with the high-speed rotation of the transmission shaft, so that the service life of the bearing is influenced. The bearing seat is made of iron casting through cutting, and is large in size and heavy in weight.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a transmission shaft intermediate strut assembly to solve the big, bearing life-span of the rigidity that proposes in the above-mentioned background art and need the cutting just can the shaping and the big problem of bulky weight. In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a transmission shaft intermediate strut assembly, includes the elastic rubber body, bearing frame and bearing, the stamping forming structure as an organic whole of bearing frame, the bearing frame is connected in the elastic rubber body inside through the mode of vulcanizing and pressure equipment, the bearing passes through pressure equipment mode and bearing frame interference fit, the lateral wall is opened before the elastic rubber body has the arc through-hole, arc through-hole annular distribution is on the elastic rubber body surface, the arc through-hole is established to 19, the dysmorphism groove has all been opened to lateral wall and back lateral wall bottom before the elastic rubber body.
Preferably, the arc-shaped through holes in the front side wall of the elastic rubber body are provided with two rings, the number of the inner rings is 10, and the number of the outer rings is 9.
Preferably, the number of the special-shaped grooves at the bottom of the elastic rubber body is 4, and the 4 special-shaped grooves are symmetrically distributed along the central axis of the elastic rubber body.
Compared with the prior art, the beneficial effects of the utility model are that: the transmission shaft middle support assembly is reasonable in structural design, simple to form, low in axial rigidity which is only 28% of that of the original support assembly, long in service life and more than 2 times that of the original support assembly; the bearing seat is formed in one step by stamping through a die without cutting; light weight, about 1/10 of the original bearing housing; small size and can be applied to narrower space.
Drawings
FIG. 1 is a schematic structural view of the present invention;
fig. 2 is a schematic diagram of the left side structure of the present invention.
In the figure: the bearing comprises an elastic rubber body-1, a bearing seat-2 and a bearing-3.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-2, the present invention provides the following technical solutions: the utility model provides a transmission shaft intermediate strut assembly, includes elastic rubber body 1, bearing frame 2 and bearing 3, bearing frame 2 stamping forming structure as an organic whole, bearing frame 2 is connected in elastic rubber body 1 inside through the mode of vulcanizing and pressure equipment, bearing 3 is through pressure equipment mode and 2 interference fit of bearing frame, the lateral wall is opened there is the arc through-hole before the elastic rubber body 1, arc through-hole ring distribution is on elastic rubber body 1 surface, the arc through-hole is established to 19, special-shaped groove has all been opened to lateral wall and back lateral wall bottom before the elastic rubber body 1.
Wherein, the arc through-hole of the lateral wall is established to two rings before the elastic rubber body 1, and the inner ring is equipped with 10, and the outer loop is equipped with 9. The dysmorphism groove of the 1 bottom of elastic rubber body is equipped with 4, and 4 dysmorphism grooves present symmetric distribution along 1 axis of elastic rubber body.
The working principle is as follows: a bearing seat 2 is manufactured by using a 1.5mm stamping part, the bearing seat 2 is installed in an elastic rubber body 1 through vulcanization and press fitting, and then a bearing 3 is connected with the bearing seat 2 into a whole in an interference fit mode, so that a transmission shaft support assembly is manufactured.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
