Abstract
The utility model discloses a belt tension device, which comprises an installation seat, a motor, a slide plate, a slide groove and an adjusting screw, wherein the motor is arranged on the slide plate and fixedly connected with the slide plate, the adjusting screw is fixedly connected with the side surface of the slide plate along the radial direction of the slide plate, the slide plate is embedded into the slide groove along the radial direction, and the slide groove is arranged on an installation seat. The belt tension device is convenient for adjusting tension of a belt of a transmission device, so that the installation precision of a belt tension mechanism is improved, the service life of a belt is prolonged, relative tolerance of two axes can be guaranteed, the transmission precision is improved, and the belt tension device is simple in structure, reasonable in design and convenient and reliable to install and use.
Description
Technical field
The utility model relates to a kind of tension device, and particularly a kind of belt stretcher is specially a kind of tension device of locomotive drive belt.
Background technique
Belt stretcher is the required device of belt drives mode, and the railway locomotive supplementary equipment also adopts this driving mode.In the locomotive equipment driving mode, the belt pulley transmission receives the restriction of locomotive installing space, weight of equipment etc., is guaranteed performance, and tension device adopts a kind of mode that changes distance between shafts.Tension device adopts the mode of Idle wheel tensioning according to differences such as driving arrangement, spaces more at present, yet, when linear velocity raising and transmitted power increase, will be very high to tensioner designs and installation requirement.
Existing through changing the regular tension device of distance between shafts; Owing to can't effectively locate; Equipment such as motor is in course of adjustment and adjust accomplish the back under the belt tension effect easily inclination misplace; Destroy the parastate of two belt wheel axis, thereby made the symmetry plane of corresponding race can't overlap the wearing and tearing that aggravate belt, caused transmission efficiency sharply to descend.
The model utility content
The purpose of the utility model is: the belt stretcher that provides a kind of installation precision that improves belt tension mechanism to require, prolong the working life of belt, thus can effectively solve the problem that exists in the above-mentioned existing technology.
The purpose of the utility model is to realize through following technical proposals: a kind of belt stretcher; Comprise fitting seat, motor, slide plate, chute and adjustment screw rod; Said motor is positioned on the slide plate and with slide plate and is connected; The adjustment screw rod is radially fixed with the slide plate side along slide plate, and said slide plate radially embeds in the chute, and chute is located on the fitting seat.
As a kind of optimal way, establish the restraining groove that matches with slide plate on the chute, slide plate is embedded in the restraining groove, and fixes through holding down bolt and chute.
As a kind of optimal way, the adjustment screw rod is provided with the adjustment nut.
Compared with prior art; The beneficial effect of the utility model: the utility model belt stretcher is adjusted the belt tightening of transmission device easily; Improve the installation precision requirement of belt tension mechanism, prolong the working life of belt, guarantee the relative tolerance of two axial lines; Improved transmission accuracy, it is simple in structure, reasonable in design, easy to install reliable.
Description of drawings
Fig. 1 is the structural representation that the utility model belt stretcher combines belt pulley.
Among the figure, the 1-belt pulley, 2-adjusts screw rod, and 3-adjusts nut, 4-slide plate, 5-holding down bolt, 6-chute, 7-fitting seat, 8-motor, 9-restraining groove.
Embodiment
Below in conjunction with specific embodiment and accompanying drawing the utility model is further described.
Disclosed all characteristics in this specification, or the step in disclosed all methods or the process are except the speciality of mutual repulsion and/or the step; All can make up by any way; Only if special narration all can be replaced by other equivalences or the alternative features with similar purpose, promptly; Only if special narration, an embodiment in a series of equivalences of each characteristic or the similar characteristics.
As shown in Figure 1; The utility model belt stretcher comprises fitting seat 7, motor 8, slide plate 4, chute 6 and adjustment screw rod 2; Said motor 8 is positioned on the slide plate 4 and with slide plate 4 and is connected, and adjustment screw rod 2 is radially fixed with slide plate 4 sides along slide plate 4, and adjustment screw rod 2 is provided with adjustment nut 3; Said slide plate 4 radially embeds in the chute 6, establishes the restraining groove 9 that matches with slide plate 4 on the chute 6, and slide plate 4 is embedded in the restraining groove 9, and fixing with chute 6 through holding down bolt 5; Chute 6 is located on the fitting seat 7.
In belt tension mechanism, pacify; After the interface installation dimension of the belt pulley 1 of dress seat 9 and transmission and relative position are set; Fitting seat 7 is fixed, through adjusting the relative tolerance requirement that chute 6 satisfies the size and two pulley groove of electrical axis position, through regulating adjustment screw rod 2 drive slide plates 4 and motor 8 radially mobile tension force and replacing belt to regulate belt in chute 6; After adjustment is accomplished, stationary positioned bolt 5 and the tight adjustment of back of the body nut 3.Move through the adjustment slide plate, belt is carried out tensioning, after the installation, safeguard and to change belt all very convenient in the future.
The working principle of the utility model: the tensioning method of this belt tension mechanism is on seat board, to offer guide groove; Make slide plate embed guide groove slip adjustment tensioning state, adjust the belt tightening of transmission device easily, guaranteed the relative tolerance of two axial lines; Improved transmission accuracy; Effectively solved and changed the problem that distance between shafts causes that the axis relative tolerance changes, highly versatile, simple and reliable, the inclination problem of misalignment that produces when can be good at solving through change distance between shafts tightening belt.
The above is merely the preferred embodiment of the utility model; Not in order to restriction the utility model; Any modification of being done within all spirit and principles at the utility model, be equal to replacement and improvement etc., all should be included within the protection domain of the utility model.
