Abstract
The utility model discloses a spindle assembly and taper lock structure. The spindle assembly and taper lock structure comprise a spindle, a bearing, a belt wheel and a taper lock sleeving the spindle, wherein a cavity is formed in the spindle and is internally provided with a pull rod, the bearing sleeves the spindle, the step-shaped taper lock with a fixing part is connected to the outer surface of the spindle in a sleeving way and is next to the left side of the bearing, an oil cylinder receiving disk is embedded in the left end of the spindle and is fixedly connected to the spindle by screwing a screw, the right end face of the oil cylinder receiving disk resists against the left end face of the taper lock, and the belt wheel sleeves the joint between the oil cylinder receiving disk and the taper lock, and is tightly and firmly connected with the taper lock by screwing a plurality of stress bolts into screw holes in the fixing part of the taper lock. According to the technical scheme, the structure design is reasonable, the use is convenient and safe, the mounting and dismounting are convenient, the connection is firm and reliable, and the balance quality is greatly improved.
Description
Technical field
The utility model relates to mechanical linking device, especially a kind of spindle part and expansion sleeve structure thereof.
Background technique
A kind of form conventional in mechanical transmission with transmission, it is applicable to the power transmission that centre distance is larger, have that stable drive, cost are low, the advantage such as minimizing and buffering vibration, be widely used with machinery in, at present, belt wheel adopts traditional key to be connected with the connection of axle mostly, and this bind mode exists some defects: in the time connecting belt wheel and axle, stability is inadequate, install loaded down with trivial detailsly, balance quality cannot reach desirable effect.
Model utility content
Be connected with axle employing key the problem that balance quality is not high that produces for solving parts in prior art, the purpose of this utility model is to provide a kind of reasonable in design, safety easy to use, easy installation and removal, connective stability and reliably, significantly promotes spindle part and the expansion sleeve structure thereof of balance quality.
For achieving the above object, the technical solution of the utility model is:
A kind of spindle part and expansion sleeve structure thereof, comprise main shaft, bearing, belt wheel and be socketed in the expansion sleeve on main shaft, described main shaft inside is cavity, pull bar is set in cavity, on described main shaft, be socketed bearing, be socketed on the outerface of spindle with the step-like expansion sleeve of fixing part and be close proximity to bearing left side side, the nested oil cylinder of main shaft left end head connects dish, oil cylinder connects dish and is fixed in main shaft by drivescrew, oil cylinder connects dish right side and withstands expansion sleeve left side, connect dish and expansion sleeve connecting part socket belt wheel at oil cylinder, belt wheel is screwed into screw and expansion sleeve in the fixing part of expansion sleeve by some stress bolts closely affixed.
As preferably, described oil cylinder connects dish end face, by some screws, angling cylinders is installed.
As preferably, between described expansion sleeve and belt wheel, clip synchronous pulley.
As preferably, described expansion sleeve is clipped in bearing and oil cylinder connects between dish.
As preferably, center, described angling cylinder right side is connected with the pull bar in spindle cavity.
Compared with prior art, the technical solution of the utility model is: reasonable in design, safety easy to use, easy installation and removal, connective stability reliably, significantly promote balance quality.
