Abstract
The utility model provides a backstop coupler. A backstop device is arranged on the coupler; the backstop device comprises a backstop sleeve, a sliding sleeve and a rotating sleeve; the sliding sleeve positioned between the backstop sleeve and the rotating sleeve can move axially and also can rotate circumferentially; teeth are arranged on the end surface, facing to the sliding sleeve, of the backstop sleeve, and the backstop sleeve is fixedly connected with an external rack; teeth are arranged on the end surface, facing to the sliding sleeve, of the rotating sleeve, and the rotating sleeve is in transmission connection with the coupler; both end surfaces of the sliding sleeve are provided with teeth, and are respectively meshed with the teeth on the backstop sleeve and the teeth on the rotating sleeve; and inclined surfaces of tooth sockets on both end surfaces of the sliding sleeve are in opposite directions. A torque can be transferred, and simultaneously backstop can be realized, so that torque transfer and reverse backstop are integrated, and compact spatial position is saved in design, particularly the design of a dual-driving mechanism; and the backstop coupler becomes simple and practicable, related connecting pieces are greatly reduced, and the cost is reduced, so that the backstop coupler is simple in structure, convenient to install and maintain, safe and reliable to use.
Description
Technical field
The utility model belongs to mechanical transmission and brake field, relates to a kind of reverse-stop type coupling with joint transmission and reverse locking function.
Background technique
Existing coupling is to connect and the transferring power moment of torsion, can not play non-return effect during counter-rotating; Non-return device only plays reverse non-return effect, does not play the effect of connection and transferring power moment of torsion.Coupling and non-return device are two kinds of devices, and two kinds of parts when concrete the application, be chosen respectively, need in design to arrange two place's locational spaces, have more correlated parts to connect with it, and installation is complicated, and cost is high.Such as having in gradient Transport Machinery in industries such as Belt Conveyings, traditional list driving is generally at an end of driving drum, drive unit to be installed, and the other end is installed non-return device.Also have on reductor shaft and non-return device and speed reducer high speed axle head directly to be installed other break etc. is installed.The shortcoming that Transport Machinery is stopped work occurs for overcoming because of the drive system maintenance or breaking down, traditional list drives and is replaced by two drivings just gradually.And must consider to install a cover non-return device during every cover drives often in two drivings, and therefore need two place's locational spaces on structural design, make that structure is bad arranges, be almost to be difficult to realize.
Traditional non-return device all adopts radially check mode, so volume is large, thick and heavy, linear friction face is little, operational safety is poor; Can occur the excessive situation of bearing capacity on same axle head as being arranged on coupling, be not suitable for and the integrated manufacturing of coupling, and it is long to have the installation and repairing time, make and the shortcomings such as maintenance cost height.
Summary of the invention
The purpose of this utility model is to provide a kind of check coupling, both can transmitting torque, can also realize reverse stop simultaneously.
the technical solution of the utility model: check coupling, be provided with non-return device on coupling, described non-return device comprises the check cover, flip sleeve and rotating sleeve, flip sleeve both can move axially also and can circumferentially rotate between check cover and rotating sleeve, the check cover is provided with tooth and the check cover is connected and fixed with extraneous frame towards the end face of flip sleeve, rotating sleeve is provided with tooth and rotating sleeve is connected with shaft coupling transmission towards the end face of flip sleeve, two end faces of flip sleeve are equipped with tooth and the tooth that puts with check respectively and the engagement of the tooth on rotating sleeve, the teeth groove bevel direction of two end faces of flip sleeve is relative.
Described coupling adopts diaphragm coupling.
The arrangement of the tooth on described check cover, flip sleeve and rotating sleeve is shape ringwise all.
The length of the tooth of the Length Ratio of the tooth that puts towards check on flip sleeve on rotating sleeve is short.
The utility model compared with prior art both can transmitting torque, can also realize reverse stop simultaneously, therefore realized that transmitting torque and reverse check unite two into one, and have saved compact spatial position, especially in the design of double driving mechanism in design, become simple, greatly reduce related fittings, reduced cost, make not only simple in structure, and convenient for installation and maintenance, safe and reliable, driving torque on year-on-year basis, volume is little, and price is low; Selecting of coupling, flexible coupling is better than rigid coupling, and being used in conjunction with of flexible coupling and non-return device well incorporates transmitting torque function and reverse locking function together, and be flawless, makes using effect perform to the optimum state.

Embodiment
as depicted in figs. 1 and 2, the check coupling, be provided with non-return device on coupling 4, coupling 4 adopts diaphragm coupling, described non-return device comprises check cover 1, flip sleeve 2 and rotating sleeve 3, flip sleeve 2 both can move axially also and can circumferentially rotate between check cover 1 and rotating sleeve 3, check cover 1 end face towards flip sleeve 2 is provided with tooth and check cover 1 is connected and fixed with extraneous frame, rotating sleeve 3 is provided with tooth and rotating sleeve 3 is in transmission connection with coupling 4 towards the end face of flip sleeve 2, two end faces of flip sleeve 2 be equipped with tooth and respectively with check cover 1 on tooth and the engagement of the tooth on rotating sleeve 3, the teeth groove bevel direction of 2 two end faces of flip sleeve is relative.
, the arrangement of the tooth on described check cover 1, flip sleeve 2 and rotating sleeve 3 is shape ringwise all.
The length of the tooth of Length Ratio on rotating sleeve 3 of the tooth on flip sleeve 2 on check cover 1 is short.
As shown in Figure 3, when 4 forwards whens running of diaphragm coupling, diaphragm coupling 4 drives rotating sleeves 3 and rotates, the tooth of the long top flip sleeve 2 in one side of tooth and drive flip sleeve 2 and rotate on rotating sleeve 3; Meanwhile, the teeth groove slope driving flip sleeve 2 of check cover 1 moves to rotating sleeve 3, until the tooth of the full-depth tooth of flip sleeve 2 and rotating sleeve 3 meshes fully, this moment, flip sleeve 2 was axially thrown off with check cover 1, and flip sleeve 2 rotates with diaphragm coupling 4 together with rotating sleeve 3.
as shown in Figure 4, when diaphragm coupling 4 shuts down, slowly reversing is descending because the inclination angle makes on belt conveyer the weight that carries can cause belt and material, at this moment diaphragm coupling 4 can drive rotating sleeve 3 backward rotation, backward rotation along with rotating sleeve 3, teeth groove slope driving flip sleeve 2 on rotating sleeve 3 moves to check cover 1, until mesh fully towards the tooth of check cover 1 and the tooth of check cover 1 on flip sleeve 2, and still have half tooth engagement towards the tooth of rotating sleeve 3 and rotating sleeve 3 on flip sleeve 2, realized that like this check cover 1 withstands flip sleeve 2, flip sleeve 2 withstands rotating sleeve 3 again, finally make the diaphragm coupling 4 can not backward rotation.
