Abstract
The utility model relates to a coupling field, in particular a coupling with a taper sleeve, comprising a taper sleeve (1) and a locking nut (2), characterized in that the taper sleeve (1) is a socket with a taper-shaped appearance, the taper sleeve (1) is sleeved outside the motor shaft, a pulley or a gear is sleeved outside the taper sleeve (1), and is locked with the locking nut (2). The utility model is adaptive to occasion of long-time large-moment positive-reverse rotation.
Description
Technical field
The utility model relates to a connection area, is specially a kind of coupling with tapered sleeve.
Background technique
Motor rotates with the cooperate driven gear or the belt wheel of key or spline by axle, is the kind of drive of using always.For to motor bearings be convenient for changing the consideration of gear, belt wheel, little Spielpassung or transition fit are adopted in all cooperations, and belt wheel or gear use locking nut and pad to lock onto motor shaft.When this kind of drive time needs motor driven gear or belt wheel to do big moment clockwise and anticlockwise alternation rotation continually in work, there are the following problems: owing to adopt little Spielpassung or transition fit, in key or spline fitted, there is small sideshake, when the motor sense of rotation changes, belt wheel or gear can be because the existence of sideshake produce the rotation with respect to motor shaft, after long-time so work, can cause belt wheel or gear and shaft shoulder contact surface abrasion, thereby cause locking nut locking to lose efficacy.Finally cause product to be scrapped in advance.In order to address the above problem, have now being connected of belt wheel or gear and motor shaft cooperated by cylinder and change cone match into, when improving the transmission effect, produced new problem again: the small radial tolerance of circular cone will cause the very big axial displacement of belt wheel or gear during owing to cone match, the part installation precision is descended, and occur that often back belt wheel or gear face and motor front-end face are installed and be close to, cause situation about can't rotate.
Summary of the invention
In order to overcome the defective of prior art, a kind of transmission device that can be adapted to long-time big moment clockwise and anticlockwise occasion is provided, the utility model discloses a kind of coupling with tapered sleeve.
The utility model reaches goal of the invention by following technical solution:
A kind of motor coupler with tapered sleeve, comprise tapered sleeve and locking nut, its structure is: tapered sleeve is that an outer surface has and the belt wheel or the gear sleeve that be complementary, taper that will be installed on the motor shaft, and tapered sleeve is enclosed within on the motor shaft, and is locked by locking nut.
The motor coupler of described band tapered sleeve, its structure is: the gradient of the tapered sleeve conical surface is between 5 °～45 °.
The utility model relies on the shaft shoulder of motor shaft that belt wheel or gear are carried out axially locating, and when locking nut was locked, between tapered sleeve wedging belt wheel or gear and the axle, contact while tensioning pulley or gear and axle by the conical surface guaranteed good transmission of power.The utility model can well be applied to the occasion of big moment clockwise and anticlockwise.
Description of drawings
Structural representation when Fig. 1 is the utility model use.
Embodiment
Below further specify the utility model by specific embodiment.
A kind of motor coupler with tapered sleeve, comprise tapered sleeve 1 and locking nut 2, as shown in Figure 1, concrete structure is: tapered sleeve 1 is that an outer surface has and the belt wheel or the gear sleeve that be complementary, taper that will be installed on the motor shaft, the gradient of tapered sleeve 1 conical surface is between 5 °～45 °, present embodiment is got 15 °, and tapered sleeve 1 is enclosed within on the motor shaft, and is locked by locking nut 2.
Claims (2)
1. motor coupler with tapered sleeve, comprise tapered sleeve (1) and locking nut (2), it is characterized in that: tapered sleeve (1) is that an outer surface has and the belt wheel or the gear sleeve that be complementary, taper that will be installed on the motor shaft, tapered sleeve (1) is enclosed within on the motor shaft, and is locked by locking nut (2).
2. the motor coupler of band tapered sleeve as claimed in claim 1 is characterized in that: the gradient of tapered sleeve (1) conical surface is between 5 °～45 °.
