The present invention aims to provide a coupling structure which facilitates work of coupling an end portion of a cable to an object to be coupled. The present invention relates to a coupling structure that couples one end of a first cable and another member. The coupling structure includes a coupling portion that couples the one end of the first cable and the other member, and a protection member that slidably houses the coupling portion. The protection member has a first opening portion which is provided at one end portion of the protection member and through which the first cable is inserted such that the first cable and the protection member are relatively movable, and a second opening portion provided at the other end portion of the protection member and from which the first cable is extendable. The coupling portion has an inclined surface that is inclined from the other member side toward the first cable side so as to abut on the second opening portion and guide the coupling portion inside the protection member in a state where the coupling portion is positioned on a radially outer side of the second opening portion when the coupling portion is relatively moved with respect to and housed into the protection member. Thus, the present invention has good coupling workability.

A linear guide bearing and an associated quick-connect system are provided. The linear guide bearing includes a carriage that moves linearly along a guide rail. The carriage includes an upper surface having a groove defined therein, and a depression formed in the groove. A tool is configured to connect to the carriage in a quick-connect fashion. To do so, the tool has a spring-loaded plunger biased downward toward the carriage. As the tool is slid along the groove of the carriage, the tip of the plunger is biased to depress into the depression in the groove. To release the tool from the carriage, a force can be applied sufficient to overcome the spring-bias force to allow the tool to lift off from the carriage.

The invention relates to a bearing cover (3) for a split bearing arrangement (1), which comprises a bearing block (2) in addition to the bearing cover (3), wherein the bearing cover (3) has a clamping surface (6), which in an assembled state of the bearing arrangement (1) fits against a counter clamping surface (5) of the bearing block (2), and wherein at least one projection (7) is formed on the clamping surface (6) and projects from the latter, which can be pushed into the counter clamping surface (5) of the bearing block (2), and which has a round or round-convex cross-sectional form in a plan view of the clamping surface (6).

A deep groove ball bearing with a split cage includes an outer ring, an inner ring, steel balls, an upper frame body, a bearing frame, and a lower frame body. Pocket grooves are formed in the bearing frame. The bearing frame is provided with a connecting piece. A first insertion groove and a second insertion groove are formed in both side walls of the connecting piece. A connecting groove is formed in a bottom surface of each of the pocket grooves. An oil storage cavity is formed in the upper frame body. The oil storage cavity is provided with a positioning flange at an opening. The positioning flange is in insertion fit with the connecting groove. The lower frame body is provided with arc-shaped grooves at positions corresponding to the pocket grooves. A connecting seat is formed on the lower frame body.

The present invention relates to a steel wire and transmission shaft connecting structure, a surgical robot, and a method. A base is included. Multiple transmission shafts penetrate through the base. A clamping block is arranged at one end of the transmission shaft. The transmission shaft is detachably clamped and fixed to a quick-connect shaft through the clamping block and a clamping slot structure arranged at one end of the quick-connect shaft. The other end of the quick-connect shaft penetrates through a butting seat and is then detachably fixed to a steel wire extending from a pipeline member. A shifting clamp is arranged between the butting seat and the pipeline member. The shifting clamp is provided with a through hole configured for the butting shaft to penetrate through. The through hole is composed of a first hole portion and a second hole portion.

A fibre-reinforced polymer composite shaft for transmitting loads along a central axis is provided. The composite shaft comprises a first interface surface extending along the central axis and comprising at least one helical groove and/or a plurality of circumferential grooves for engaging with at least one corresponding helical ridge and/or a plurality of corresponding circumferential ridges of a second interface surface of an end fitting. The at least one helical groove and/or the plurality of circumferential grooves comprises at least one flank with a flank angle of between 32? and 51?. In such an assembly, a preload structure is arranged to provide a radial biasing force to bias the first interference surface against the second interference surface.

Disclosed herein includes a solar panel angle adjustment system for actuation with a single hand. The solar panel adjustment system includes a tensioned variable ribbon configured to adjust the angular position of the mounting panel. The system includes a gear adapted to adjust the tensioned variable ribbon and configured to translate between a first position and a second position. Additionally, in some examples, the system includes a gear shaft mechanically coupled with the gear and configured to translate between the first and second position and actuate the gear, but the gear shaft is locked when disposed in the first position. The system may also include a spring adapted to bias the gear from the second position to the first position. Furthermore, the tensioned variable ribbon can adjust the angle of the mounting panel in response to the gear shaft actuating the gear in the second position.

A bearing structure comprises: two bearings arranged in an axis direction and having outer rings and inner rings; and a spacer interposed between the bearings. The spacer comprises: a ring-like outer ring spacer interposed between the outer rings of the two bearings arranged in the axis direction, and having an insertion hole penetrating the outer ring spacer in a radial direction RD and into which a jig is to be inserted; and a ring-like inner ring spacer interposed between the inner rings of the two bearings arranged in the axis direction, and having an engagement part to make engagement with the jig inserted into the insertion hole. The one bearing is capable of being pulled out together with the spacer from a rotary shaft supported by the inner rings by pulling the jig in the axis direction inserted into the insertion hole and engaged with the engagement part.

An unmanned aerial vehicle includes a propulsion system including a driving device having a main body, a driving shaft rotatable relative to the main body, and a locking member disposed on the main body. The locking member includes at least one snap-fitting member. The propulsion system also includes a propeller coupled with the driving device, the propeller including a blade base and a blade mounted on the blade base. The at least one snap-fitting member is configured to snap-fit with the propeller. The propulsion system also includes an elastic abutting member sleeve coupled with the driving shaft, a first installation foolproof member disposed on the blade base, and a second installation foolproof member disposed on the locking member.
