Abstract
A kind of mounting structure of low-speed diesel engine bearing cap, include bearing support and bearing cap, wherein, the both sides of bearing support are provided with bearing block bolt hole, the both sides of bearing cap are provided with and the bolt of bearing cap hole of coaxial line corresponding to this bearing block bolt hole, bearing cap is arranged on bearing support by hydraulic bolt and nut, it is characterized in that: the described bolt of bearing cap hole of described both sides and the axis in bearing block bolt hole slope inwardly, described hydraulic bolt one end is spun solid on bearing block bolt hole through bolt of bearing cap hole, the other end spins nut, horizontal component is produced to bottom described bearing cap by straining this hydraulic bolt.The mounting type of the utility model tilt bolt formula contributes to producing horizontal component to bottom bearing cap after hydraulic bolt is strained, bearing cap and bearing support are locked more firmly, avoid vibration and the bearing cap that causes loosens and Horizontal displacement, effectively decrease the width of bearing support simultaneously, make diesel engine overall structure compacter.
Description
Technical field
The utility model relates to a kind of diesel engine assembly structure, is specifically related to a kind of mounting structure of low-speed diesel engine bearing cap, belongs to Diesel Engine Technique Field.
Background technique
Low-speed diesel engine has generally comprised bent axle, main axle bush, support, bearing support and bearing cap, refer to Fig. 1, bearing support 1 is installed in frame, and bearing cap 2 is arranged on bearing support 1 by hydraulic bolt 3 and nut 4, and hydraulic bolt 3 and tightening of nut 4 are completed by hydraulic elongator.
The conventional mounting structure that existing bearing cap 2 is fixed on bearing support 1 is, bearing support 1 is provided with axially vertical bearing block bolt hole 11, bearing cap 1 is provided with corresponding axially vertical bolt of bearing cap hole 21, position with it, hydraulic bolt 3 one end is spun solid on bearing block bolt hole 11 through bolt of bearing cap hole 21, the other end spins nut 4, is fixed on bearing support 1 by bearing cap 2 by hydraulic elongator.
The mounting structure of existing bearing cap 2 can after low-speed diesel engine operates certain hour, and the coupling mechanism force due to hydraulic elongator is not enough or vibrate and cause bearing cap 2 to loosen, and even occurred level displacement, serious meeting causes equipment accident.
Model utility content
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of mounting structure of novel low-speed diesel engine bearing cap is provided, this mounting structure adopts tilting bolt mounting type, bearing cap is produced to the component of level, impels bearing cap and bearing support rigid contact; Reduce the width of bearing support simultaneously.
The technical scheme in the invention for solving the technical problem is as follows:
A kind of mounting structure of low-speed diesel engine bearing cap, include bearing support and bearing cap, wherein, the both sides of bearing support are provided with bearing block bolt hole, the both sides of bearing cap are provided with and the bolt of bearing cap hole of coaxial line corresponding to this bearing block bolt hole, bearing cap is arranged on bearing support by hydraulic bolt and nut, it is characterized in that: the described bolt of bearing cap hole of described both sides and the axis in bearing block bolt hole slope inwardly, described hydraulic bolt one end is spun solid on bearing block bolt hole through bolt of bearing cap hole, the other end spins nut, horizontal component is produced to bottom described bearing cap by straining this hydraulic bolt.
Further, described bearing support is respectively provided with a boss inside two of described bearing cap, strains the boss close contact that described hydraulic bolt makes this bearing cap and bearing support.
Further, the bearing block bolt hole of described both sides, bolt of bearing cap hole and boss are all symmetrical.
Further, the head of described hydraulic bolt, away from described bearing support, produces the space of the described hydraulic elongator of more arrangements.
Compared with existing mounting structure, the utility model achieves following technique effect:
1) contribute to after hydraulic bolt tension by the bearing cap mounting structure of tilting bolt, to the component producing level bottom bearing cap, thus impel bearing cap and bearing support boss close contact, two boss produce the retention force to center to bearing cap symmetrically, bearing cap is locked on bearing support more firmly, avoids vibration and the bearing cap that causes loosens and Horizontal displacement.
2) hydraulic bolt of tilting is away from bearing support, creates more space to place hydraulic elongator, thus effectively reduces the width of bearing support, make diesel engine overall structure compacter.
Accompanying drawing explanation
Fig. 1 is structure diagram of the present utility model.
Embodiment
Be further elaborated below in conjunction with the mounting structure of the drawings and specific embodiments to low-speed diesel engine bearing cap described in the utility model, but protection domain of the present utility model should do not limited with this.
Refer to Fig. 1, the mounting structure illustrating a kind of low-speed diesel engine bearing cap includes bearing support 1 and bearing cap 2.The both sides of described bearing support 1 are provided with symmetrical bearing block bolt hole 11, the both sides of described bearing cap 2 are provided with symmetrical bolt of bearing cap hole 21, this bolt of bearing cap hole 21 and coaxial line corresponding to this bearing block bolt hole 11, the bolt of bearing cap hole 21 of both sides and the axis in bearing block bolt hole 11 slope inwardly.It is all symmetrical that described bearing support 1 is respectively provided with boss 22, two boss 22 inside two of described bearing cap 2.Described bearing cap 2 is arranged on bearing support 1 by hydraulic bolt 3 and nut 4, described hydraulic bolt 3 one end is spun solid on bearing block bolt hole 11 through bolt of bearing cap hole 21, the other end spins nut 4, by straining this hydraulic bolt 3, horizontal component is produced to the bottom of described bearing cap 2, make two boss 22 close contacts of this bearing cap 2 and bearing support 1, to make bearing cap 2 be locked in more firmly on bearing support 1, avoid vibration and the bearing cap 2 that causes loosens and Horizontal displacement.The bearing block bolt hole 11 of tilting and bolt of bearing cap hole 21 make the head of described hydraulic bolt 3 away from described bearing support 1, produce more space to settle described hydraulic elongator, effectively decrease the width of bearing support 1 simultaneously, make the more compact structure of diesel engine entirety.
Be more than a best embodiment of the present utility model, protection domain of the present utility model can not be limited with this.What protection domain of the present utility model also comprised other is apparent conversion for those skilled in the art and substitutes.
