Abstract

The utility model discloses a composite coupling, comprising a main transmission component and a secondary transmission component. The main transmission component is connected with a power output shaft and the secondary transmission component is connected with a bearing axle; the main transmission component is an external gear sleeve and the internal gear ring with a connection disc, which match with each other; the secondary transmission component is a ladder-shaped connection hub and a connection spanner ring; the connection hub is homocentric with the external gear sleeve and the connection spanner ring is arranged on the step of the connection hub and is pressed on the connection hub by a connecting piece; a connection outer ring arranged outside the connection hub and the connection spanner ring is integrated with the connection disc of the internal gear ring by connection bolts which are arranged at circumference evenly; and a friction ring is embedded among the joint surface of the connection hub, the connection spanner ring and the connection outer ring. A large adjusting clearance exists between the external gear sleeve and the internal gear ring. The utility model does not have high requirement on concentricity and can be installed conveniently. Because the friction ring is embedded among the joint surface of the connection hub, the connection spanner ring and the connection outer ring, when locking and other faults happen at a load end, the friction ring slips, thus protecting the equipment.

Description

Compound coupling
Technical field
The utility model relates to coupling, especially relates to compound coupling special-purpose on a kind of large lifting equipment or the disintegrator.
Background technique
Coupling uses extensively at mechanical field, and its effect is the transmission that realizes moment of torsion between the diaxon by transmitting assemblies, and commonly used on coal mine machinery, Hoisting Machinery, crushing mechanism have cog-wheel coupling and a friction coupling.Cog-wheel coupling is that the interior external toothing (transmitting assemblies) by mutual coupling is connected with the transmission shaft interference fit by flat key respectively and reaches the purpose that moment of torsion transmits, because concentricity requirement not high (error can allow 2-3mm) to transmitting assemblies, so be convenient to install, but in the course of the work if during situation such as load is excessive or stuck, can cause the fracture of coupling component, damage equipment; Friction coupling is by the higher connection wheel hub of concentricity requirement and connects outer shroud is realized moment of torsion between the diaxon by the friction ring between the two transmission; excessive or when situation such as stuck occurring when load; the junction plane of friction ring can skid; to realize protection to equipment; but owing to, very inconvenience is installed to connecting wheel hub higher with the concentricity requirement that is connected outer shroud (10 μ m).
The model utility content
The purpose of this utility model is to provide a kind of compound coupling that promptly makes things convenient for installation can shield again.
For achieving the above object, the utility model can be taked following technical proposals:
Compound coupling described in the utility model comprises main transmission assembly that links to each other with pto and the auxiliary driving assembly that links to each other with bearing axle, and described main transmission assembly is external tooth cover that cooperatively interacts and the ring gear that has land; Described auxiliary driving assembly is for being connected wheel hub and being sleeved on the described connection that is connected on the wheel hub step and pulling ring with the concentric stepped shaft of described external tooth cover, described connection is pulled ring and is pressed together on the connection wheel hub by link, be sleeved on described connection wheel hub and pull the outer connection outer shroud of ring and be combined as a whole with the land of described ring gear, connecting wheel hub, connecting between the junction plane of pulling ring and connection outer shroud and be inlaid with friction ring by the uniform connecting bolt of periphery with being connected.
The junction plane that described connection wheel hub and connection are pulled between ring and the friction ring is a v-shaped structure.
Described link is the adjustment bolt that has belleville spring.
Offer the oil hole that is connected with the flank of tooth of external toothing on the described ring gear.
Offering an annular groove, be provided with supported spring in it with the outer circumferential face center that is connected the contacted friction ring of outer shroud.
Advantage of the present utility model is that the main transmission assembly is external tooth cover that cooperatively interacts and the ring gear that has land; Described auxiliary driving assembly is for being connected wheel hub and being sleeved on the described connection that is connected on the wheel hub step and pulling ring with the concentric stepped shaft of described external tooth cover, described connection is pulled ring and is pressed together on the connection wheel hub by link, being sleeved on described connection wheel hub pulls the outer connection outer shroud of ring and is combined as a whole by the uniform connecting bolt of periphery and the land of described ring gear with being connected, connecting wheel hub, connect between the junction plane of pulling ring and connecting outer shroud and be inlaid with friction ring, the utility model is combined as a whole gear coupling and friction coupling, form compound coupling, as between the external tooth cover of main transmission assembly and the ring gear owing to have bigger adjusting play, concentricity requirement to integral coupling is not high, and is more convenient during installation; During work as the connection wheel hub of auxiliary driving assembly, connect between the junction plane of pulling ring and connecting outer shroud and be inlaid with friction ring; three junction planes of friction ring can produce and skid when faults such as locking occurring at load end; play protection, be unlikely to damage equipment equipment.
The junction plane that connection wheel hub and connection are pulled between ring and the friction ring is a v-shaped structure, can increase its frictional force; Link is the adjustment bolt that has belleville spring, can adjust according to the load size to connect the pressure force of pulling ring; Offer the oil hole that is connected with the flank of tooth of external toothing on the described ring gear, can in time be lubricated it; Offering an annular groove with the outer circumferential face center that is connected the contacted friction ring of outer shroud, be provided with supported spring in it, can adjust the pressure of friction ring.
